[00:00:52] <CodeWar> Q: <a> are there any licensing restrictions on programs built using oracle studio. <b> have we encountered the issue of building GPL programs with studio? any reason to believe the two dont play well

[00:32:48] <sjk> I need an operating system for creating a couple of VPSes. I am used to using FreeBSD (and I'm currently using ZFS), but FreeBSDs virtualization options do not seem optimal. Is OpenSolaris something for me?
[00:46:26] <Cyrus> sjk: http://openindiana.org/ may be.
[00:46:57] <Cyrus> I can tell you from experience that zones are better than Jails.
[00:48:03] <sjk> Cyrus, would I be able to run other operating systems using "zones"? Like, could I use FreeBSD as a guest OS?
[00:50:08] <Cyrus> sjk: Not really.
[00:50:15] <Cyrus> It's not like Xen.
[00:50:28] <sjk> Hrm, but Solaris does have Xen, doesn't it?
[00:50:56] <Cyrus> I would not know, I've never seen references to it nor have I ever used it.

[01:17:48] <macros73> Okay. For a large cp (~20GB), the first GB copies over smb at ~40MB/s. Then it drops to 16.5 or so. Copying from client to solaris/smb. Any thoughts?
[01:17:55] <macros73> ls
[01:20:09] <tsoome> first gb will go to the cache, then disks will get hit;)
[01:21:37] <macros73> Four disks, two mirrors in one pool...should sustain higher than 16MB/s, shouldn't they?
[01:22:13] <tsoome> no idea, monitor them with iostat -xnM 1
[01:23:16] <tsoome> well, sequential write yea, one would expect that should be, but it also depends how the free blocks are aligned etc...

[01:44:51] <macros73> huh.
[01:45:25] <macros73> Still testing, but dedup appears to slow write times from over 100 Mw/S to under 10.
[01:45:47] <tsoome> how much ram you have ?
[01:45:50] <macros73> 8G
[01:45:57] <tsoome> and storage?
[01:46:14] <macros73> 1.15T
[01:46:27] <tsoome> dedupe ratio?
[01:46:31] <macros73> 1.15
[01:46:39] <tsoome> forget it;)
[01:46:44] <tsoome> well, ok
[01:46:46] <macros73> wait, now it's 1.16
[01:46:52] <tsoome> lol
[01:47:12] <tsoome> you wanna see something like 8:1 or 10:1
[01:47:13] <macros73> So...if I really want to use dedup...more RAM, or l2arc cacje
[01:47:18] <macros73> yeah.
[01:47:27] <tsoome> ehat data is that?
[01:47:30] <tsoome> what<'
[01:47:38] <tsoome> bloody keyboard....
[01:47:41] <tsoome> :D
[01:47:41] <macros73> mixed bag. comic archives, music, videos, media, etc.
[01:47:44] *** Praematura has left #opensolaris
[01:47:51] <tsoome> normal fileserver?
[01:47:56] <macros73> home fileserver
[01:48:05] <tsoome> i mean, not backup server ?
[01:48:13] <macros73> Nah, not a backup server.
[01:48:31] <tsoome> ah, forget it, fileserver and dedupe wont play together
[01:48:47] <tsoome> for that money for rm, you will get loads of disk space
[01:48:48] <macros73> So, turn it off unless I start playing with vm. And if I play with vm, test turning it on a separate share for the vm images?
[01:48:50] <tsoome> ram*
[01:49:19] <tsoome> tbh.... i actually doubt its worth for vm images
[01:49:26] <macros73> huh.
[01:49:31] <macros73> so what good /is/ dedup?
[01:49:49] <tsoome> i mean, if we are talking about ratios like 10:1, it means you should have like 10 nearly identical images
[01:50:14] <tsoome> most obvious target is backup
[01:50:15] <macros73> Ah. And these days, vmware/etc have dedup built in anyway, with master images and such.
[01:50:24] <tsoome> yep
[01:50:46] <tsoome> thats why is was writing i doubt its useful:)
[01:51:07] <macros73> ok. I definitely see big improvements on local cp. Going to test network cp next, and if it is also a dramatic improvement, off with dedup
[01:51:11] <tsoome> there is also another consideration
[01:51:49] <macros73> ?
[01:52:10] <tsoome> if you have vm images deduped, and images/data amount is so big they wont fit to read cache, then the dedupe will mean you will have read hotspot on disk
[01:52:36] <macros73> ...which I guess is bad?
[01:52:56] <tsoome> indeed, since disks can only do so much reads
[01:53:16] <tsoome> without dedupe, those images are spread
[01:53:33] <macros73> okay. first gb went fast last time, then write speed tanked, which implies cache. Will see what the sustained copy speed iover network s now on a test share with dedup off.
[01:54:40] <macros73> We're past the first GB now and we're sustaining ~50MB/s
[01:55:21] <macros73> should still be faster, but the bottleneck now is the single disk in the client which is sending data to the server
[01:55:24] <macros73> or so I assume
[01:55:25] <tsoome> dedupe by itself, can be very useful on backups, especially on VM backups, because people are forced often to do full image (raw) backups
[01:56:22] <macros73> so if I do use dedupe on a backup share, zfs is smart enough only to store a dedupe table for that data, yes? Not all the other pools?
[01:56:29] <tsoome> 50MB/s is quite reasonable for single disk
[01:56:57] <tsoome> yea, DDT is only for daduped dataset(s)
[01:57:12] <tsoome> de'*
[01:57:18] <tsoome> :D
[01:57:29] <macros73> cool. Thanks for clarifying as always. I am seeing write spikes of 362M/s on the pool now.
[01:57:51] <macros73> It waits until it gets full from the client then spits the data out into the pool in a burst.
[01:58:18] <macros73> but from the client's perspective, it can keep sending as fast as its able, which is all I wanted in the first place.
[01:59:10] <tsoome> yep, default write cache will write stuff down at max 30 sec intervals unless its sync mode write
[03:00:46] <tsoome> with just one client, you will likely see those 30 secc bursts
[03:01:06] <CIA-49> SFE tom68: experimental/SFEvlc-1.1.4.1.spec: release to experimental, needs SFEqt47-gpp in new path layout and more work to find QT
[03:02:39] <tsoome> but yea, for normal filesystem, the dedupe is almost useless, the few blocks you are able to save is really not worth the expenses
[03:02:47] <macros73> yup. lesson learned.
[03:03:05] <macros73> well, this test was form cli. Curious to see if OSX finder gets worse performance. It seems to do dumb things.
[03:03:54] <tsoome> for OSX, if your clients are doing searches a lot, you may wanna consider netatalk instead of cifs
[03:04:00] <tsoome> or nfs
[03:04:28] <tsoome> the latest netatalk beta versions have support for data indexing via dbd interface
[03:04:56] <tsoome> but then again, its still in beta only:)
[03:06:05] <tsoome> few tests i did with it were quite nice, once the first search was done and the database was filled
[03:10:15] <tsoome> http://netatalk.sourceforge.net/2.2/ReleaseNotes2.2beta3.html - Support for fast AFP searches (CNID backend "dbd" only)
[03:11:44] <tsoome> oh crap, there was an time warp from 2:59 to 4:00 ... :(
[03:14:00] <Hedonista> european daylight savings time tonight?
[03:14:27] <macros73> ive had HORRID experiences with OSX NFS and this server, but that may also have been dedup related
[03:14:47] <tsoome> yea
[03:14:51] <macros73> will retest with dedup off
[03:14:59] <macros73> and will take a look at neta, thanks for the link
[03:15:44] <macros73> Did you see a commercial version of ZFS is being brought to OSX sometime this summer?
[03:15:48] <tsoome> nfs doesnt cope too well with mobile stuff like laptops, static workstations are better i would suppose
[03:16:23] <tsoome> but cifs/afp will survive network disconnects way better for desktops
[03:16:44] <macros73> My main home computer is a 27" iMac, I don't carry it around much. :D
[03:16:56] <macros73> but do have a few laptops, iPad, etc
[03:17:02] <tsoome> for user its easier to manage, no need to remember to disconnect shares before closing lid etc;)
[03:17:28] <macros73> I've also found smb to be a little easier to setup as there is no need to worry about UID
[03:17:43] <macros73> it just kinda automatically maps the logon user to the native Solaris user
[03:17:49] <tsoome> that too
[03:18:02] <macros73> where nfs defaults to matching on UID
[03:18:11] <tsoome> with search boost in netatalk 2.2, its really looking nice
[03:18:24] <macros73> search boost?
[03:18:35] <tsoome> yep
[03:19:08] <tsoome> as they need to store osx data in database, they did add support for spotlight indexing
[03:19:12] <macros73> okay, so you have to setup the dbd backend then
[03:19:19] <macros73> That is pretty cool.
[03:19:19] <tsoome> yep
[03:20:32] <tsoome> the first serarch will still burn disks pretty nicely, but after it had chance to warm up dbd, then next searches are really smooth
[03:20:53] <macros73> will have to try that. smb should be "good enough" for now, but I likey spotlight indexing.
[03:21:00] <macros73> ooh, and timemachine volume support
[03:21:26] <tsoome> that has been for a while, we are using it quite some time
[03:22:20] <tsoome> were using iscsi before, but it has the same issue as nfs - you need to remember ro disconnect disk before disconnecting the net
[03:22:28] <tsoome> s/ro/to/
[03:22:43] <macros73> will give it a whirl once i get settled in with turning off dedup
[03:22:44] <tsoome> if you dont, you need reboot to fix it...
[03:23:02] <macros73> also poking at getting webdav support on some of the shares
[03:23:16] <macros73> but Goodreader on the iPad also supports ftp, so may just do that for now
[03:23:28] <tsoome> mod_dav with apache?
[03:23:48] <macros73> yeah
[03:24:02] <macros73> just haven't made time to play with it yet. Have some running at work, so familar with the basics
[03:24:14] <macros73> though that's on linux, need to see where Solaris hides the conf files
[03:24:59] <tsoome> havent checked that, havent had any need for my ipod, but as ill get my pad soonish, it may be on list soon:D
[03:25:16] <tsoome> its in apache conf as usual
[03:25:42] <tsoome> mod_dav just will add new option, like "dav = on" there
[03:25:58] <tsoome> in directory block.
[03:26:00] <macros73> lol. two apps you want right away: goodreader (best PDF reader there) and reeder (Google Reader client, far better than using Google Reader)
[03:27:28] <tsoome> will see. my pad is at friends just now, just need to wait next weekend to fisit the friend and pick it:D
[03:27:32] <macros73> and kindle, naturally
[03:27:36] <tsoome> visit*
[03:27:55] <macros73> How long will it take to wipe your friend's fingerprints off? :D
[03:28:02] <tsoome> i have kindle app, but i did decide to go with ibooks, at least for the time being
[03:28:28] <tsoome> because the first test i did with amazon was fail
[03:28:29] <macros73> really? I wanted to make sure I could still access the files on a PC or Kindle DX, so went with Kindle.
[03:28:32] <macros73> lol
[03:28:36] <macros73> what failed?
[03:28:42] <tsoome> well, they did
[03:28:56] <tsoome> i was thinking like, well, lets buy my first ebook.
[03:29:12] <tsoome> so, did pidk asimov's foundation
[03:29:16] <tsoome> pick*
[03:29:27] <tsoome> and the told, i cant get it
[03:29:34] <tsoome> so i told, fuck you.
[03:29:42] <macros73> oh crap. I turned off dedup...do I have to copy all my files to another pool and then back again?
[03:30:04] <tsoome> yes, the famous BP rewriter issue
[03:30:31] <macros73> Argh.
[03:30:44] <macros73> i will have performance issues if I don't?
[03:30:49] <tsoome> in short, on my first ebook shopping, they were telling, "the copiright prevents to buy this book"
[03:31:00] <macros73> Wow, that does suck
[03:31:03] <tsoome> copyright*
[03:31:11] <macros73> I haven't had that issue, but all I've bought are reference books
[03:31:54] <tsoome> well, i do have that book on paperback; both in english and translated version in estonian.
[03:33:11] <tsoome> so, i did grab the first torrtnt and i have over 6k ebooks now. some crap (as usual), some i really like, and would buy, but if they dont wanna get my money, its not my problem.
[03:33:39] <macros73> yup. I have a mix of Kindle & PDF files.
[03:33:52] <macros73> my archives have gone from mostly video to mostly PDF. :D
[03:34:14] <tsoome> i kinda liked the kindle idea - buy the book and you get it synced to all your kindle devices
[03:35:44] <tsoome> but well. cant help if they are still living in previous century and have no clue how to get customers.

[03:40:12] *** CodeWar has joined #opensolaris
[03:40:46] <tsoome> btw if you wanna use %u for timemachine share names, and still wanna get it broadcasted with bonjour, you need to create directory for nobody (or whatever your anonymous user is)
[03:41:01] <macros73> lol, always a catch :D
[03:42:00] <tsoome> ye, if that path doesnt exist, it wont broadcast the service:)
[03:43:35] <macros73> i better make a note of that
[03:44:38] *** CodeWar has quit IRC
[03:44:53] <macros73> Does your testing show better transfer speeds for netatalk v. smb?
[03:45:03] <macros73> for a solaris server -> mac client?
[03:45:19] <tsoome> without bonjour you need to first connect to the share, then you can select it for TM target
[03:46:11] <tsoome> not really - i would suppose cift would win, because its kernel service, but then again, i dont know what is protocol overhead
[03:46:42] <tsoome> and here we are using afp only for TM really

[08:23:14] <CodeWar> trying to wire up static ip address is the following correct or is it more involved than that ==> ifconfig e1000g1 plumb ; ifconfig e1000g1 inet 192.168.0.109 netmask 255.255.255.0 broadcast 192.168.0.0 ; ifconfig e1000g1 up
[08:23:31] <CodeWar> my router has reserved 192.168.0.109 for that particular mac address
[08:24:03] <bdha> If it's serving it via DHCP, why not just say 'ifconfig e1000g1 dhcp' after bringing up the iface?
[08:24:12] <bdha> And setting /etc/dhcp.e1000g1 or whatever the arg is.
[08:24:17] *** p3n has joined #opensolaris
[08:24:22] * bdha doesn't use dhcp client on Solaris much.
[08:24:42] *** bobbyz_ has quit IRC
[08:24:44] <CodeWar> bdha, this is step 1 in getting AI to work ... so no I cant use dhcp or so I m told
[08:25:17] <bdha> What?
[08:25:21] <bdha> For the AI server?
[08:25:27] <bdha> Or AI to serve DHCP?
[08:25:45] <bdha> http://mexico.purplecow.org/static/ai1.pdf # Read that if you haven't.
[08:25:52] <CodeWar> bdha, AI server ... my understanding is that installadm will start dhcp server with the -i command
[08:25:57] <CodeWar> oh noooooooo that one didnt help one bit :)
[08:26:04] <bdha> Huh.
[08:26:12] <bdha> uhm, ok.
[08:26:15] <bdha> Well, good luck.
[08:26:31] <CodeWar> let me explain ... i followed htose steps to the "T" and mid way result execution didnt match the tutorial .. so I gave up :)
[08:27:32] <CodeWar> anyways I m trying to cover this in steps: Step 1: learn how to setup static IP address for Solaris Step 2: setup a DHCP server on Solaris box Step 3: make sure another machine on subnet can come up with this dhcp server
[08:27:39] <CodeWar> Step 4: do the real AI thing ...
[08:29:48] <CodeWar> what .. nobody knows how to setup a static IP address on Solaris?
[08:32:51] <_Tenchi_> ipnodes, netmask, and hostname files on solaris10 ?
[08:33:31] <CodeWar> _Tenchi_, ok so this is what caused my doom using the link bdha just mentioned... it assumes the guy knoww how to do this .. well too bad I dont
[08:33:35] <CodeWar> so any link / tutorial?
[08:33:58] <_Tenchi_> you're on solaris 10 ?
[08:34:07] <CodeWar> Solaris 11 express ..
[08:34:21] <_Tenchi_> ah solaris11 express is totally different
[08:34:35] <CodeWar> no wonder half the tutorials didnt work for me :)
[08:34:42] <_Tenchi_> hah yeah
[08:34:56] <CodeWar> so waht gives .. how is this done on Soalris 11
[08:35:04] <_Tenchi_> on solaris 11 express i've only used nwam
[08:35:54] <CodeWar> thats fine .. is there a file I can change from dhcp to static ip and restart nwam?
[08:36:01] <_Tenchi_> i read the network guide in the solaris 11 express docset
[08:36:30] <_Tenchi_> i think The Right Way is not to change files, but ti use nwamcfg to change the files for you
[08:38:00] <CodeWar> now that I would really like... waht doc is this again
[08:38:26] <CodeWar> changing 5 files has been making me mutter curses at Solaris engineers for so long ... seriously ? these guys are so dumb they cant write a script that automates this :))
[08:38:47] *** bobbyz_ has joined #opensolaris
[08:39:44] <_Tenchi_> do you know where the official solaris 11 express documentation is located?
[08:40:07] <_Tenchi_> http://www.oracle.com/technetwork/server-storage/solaris/documentation/index.html
[08:40:41] <_Tenchi_> http://www.oracle.com/technetwork/server-storage/solaris11/documentation/index.html
[08:40:50] <_Tenchi_> the first link is sol10, 2nd is sol11
[08:40:59] *** markl__ has quit IRC
[08:41:26] <CodeWar> got that but this is needle in haystack .. what exactly am I searching for
[08:42:46] <CodeWar> Jesus reading the man ... this is another red herring .. I ll probably spend 3 hours on nwamcfg only to know this doesnt work
[08:42:54] <CodeWar> please only say if you ve done this successfully ..
[08:42:59] <CodeWar> I m too frustrated to try out new things
[08:43:21] <_Tenchi_> hehe, yes i've done it successfully many times
[08:43:27] <_Tenchi_> otherwise i would say anything
[08:44:06] <CodeWar> sorry man .. but just checking .. so using nwamcfg (whatever this is .. I ll find out but ) I can setup static ip address on Solaris 11?
[08:44:18] <_Tenchi_> network automatic configuration
[08:44:31] <_Tenchi_> automagic actually
[08:44:43] <CodeWar> ok good enough .. I ll give it a try
[08:44:48] <CodeWar> thanks _Tenchi_
[08:45:02] <CodeWar> I might have to kill you if it doesnt work but then who knows
[08:45:06] <_Tenchi_> but yeah you setup a control profile, control unit, and location with nwamcfg
[08:47:47] <_Tenchi_> http://download.oracle.com/docs/cd/E19963-01/pdf/821-1458.pdf
[08:49:13] *** markl__ has joined #opensolaris
[08:50:15] <CodeWar> _Tenchi_, you ve done this right.... let me know what exactly should I be looking in taht doc ... enough to wire up static ip address and not read 200 pages :)
[08:53:09] <_Tenchi_> the essentials are knowing what an ncp, ncu, and location are
[08:53:46] <_Tenchi_> ncp is a profile, so you create that, and then in the ncp you create two "ncu" which maps the physical interface to the ip
[08:54:15] <_Tenchi_> then you create a location and config the location with name resolution info... dns servers, etc
[08:54:16] <CodeWar> In OSOL System->administration ->network is this the same thing that comes up?
[08:54:36] <_Tenchi_> er, you talking about the GUI?
[08:54:40] <CodeWar> you bet
[08:55:20] <_Tenchi_> yeah i've done the same thing with the GUI on some laptops, but i dont remember the specifics, it was actually pretty intuitive and i got them up and running with a static ip pretty quickly
[08:55:56] <_Tenchi_> does the GUI show NCPs and Locations ?

[09:08:58] <CodeWar> _Tenchi_, it doesnt but its intuitive enough ip/iface/static vs dhcp ... anyawys I tried that but it doesnt work (meaning the iface is not active) and on a reboot system hangs
[09:09:38] <CodeWar> one of gazillion things could have gone wrong but phase shift 180 deg... does anybody happen to know if I pulled a disk out from my T1000 and replaced it with a SATA cdrom if I can boot out of that

[09:16:28] <CodeWar> http://sparcv9.blogspot.com/2010/11/quick-solaris-11-express-walkthrough.html this seems to come the closest let me try it out
[09:24:59] *** bobbyz_ has joined #opensolaris
[09:25:28] <_Tenchi_> looks too easy :)
[09:26:59] <CodeWar> yep and it doesnt work either
[09:27:32] <CodeWar> "ipadm: could not create address: Persistent operation on temporary object"
[09:28:13] <_Tenchi_> oh yeah that error sounds familiar
[09:28:38] *** hsp has joined #opensolaris
[09:31:49] <_Tenchi_> wait
[09:32:05] <_Tenchi_> i think you have to switch networking setups if you want to use ipadm
[09:32:20] <CodeWar> what does that mean
[09:32:37] <_Tenchi_> svcs physical
[09:32:41] <CodeWar> ahh
[09:32:56] <CodeWar> you mean default and not nwam?
[09:33:01] <_Tenchi_> there should be "default" and an "nwam"
[09:33:19] <CodeWar> yep its nwam right now
[09:33:25] <_Tenchi_> yeah you might have to switch from nwan to default to use ipadm directly
[09:35:36] <CodeWar> _Tenchi_, you re good!
[09:35:50] <_Tenchi_> did it work ?
[09:35:52] <CodeWar> yep
[09:35:55] <_Tenchi_> nice
[09:36:28] <CodeWar> its on a vbox the route -p and ipadm show-addr show decent output and the commands didnt show any error I ll try it on the real box next
[09:37:09] <CodeWar> btw thanks a lot dude!!
[09:37:29] <_Tenchi_> not a problem
[09:37:45] <_Tenchi_> such a shame that there are so many bloggers that can't blog a good, accurate tutorial
[09:38:02] <CodeWar> they assume the reader is not networking dumb ass like me :)
[09:38:13] <CodeWar> probably their target audience is sysadmins who know most of this
[09:38:24] <_Tenchi_> then they should state that
[09:38:39] <CodeWar> yep
[09:38:39] <_Tenchi_> otherwise google grabs their blog and serves it out to people that dont know any better
[09:38:47] <CodeWar> oh yes ... ask me about it :)
[09:38:52] <jelmd> newbies should read the manual!
[09:38:55] <CodeWar> so many smarty pants blogs have I read
[09:39:02] <_Tenchi_> yeah, that manual is pretty thick though
[09:39:05] <CodeWar> jelmd, oh dear. .. I have tried
[09:39:10] <_Tenchi_> i'm big on reading the docs and i havent even done that myself yet
[09:39:54] <jelmd> yeah - anybody who is able to read, has a clear advantage ;-)
[09:40:00] <_Tenchi_> haha
[09:40:41] <CodeWar> let me explain first hand what the problem with reading manuals is .. they re not sequential
[09:41:02] <CodeWar> they ll assume that area is the only thing you need to know and they ll explain it in details .. for e.g., the AI manual will explain AI in details
[09:41:17] <CodeWar> but if you re not familiar with DHCP / static ip address setup then you re toast ... which is where blogs come in
[09:43:20] <jelmd> no - you go to http://www.oracle.com/technetwork/documentation/solaris-11-192991.html an pickup the relevant manual
[09:44:03] <_Tenchi_> you do have to kind of skim each book to see what the general scope of it is
[09:44:49] <CodeWar> theres a difference between a tutorial and a reference but heck I should read both so who knows
[09:44:49] <_Tenchi_> but in a lot of cases the books say something like "before reading this, make sure you're familiar with the concepts in this other book"
[09:45:06] <CodeWar> yes prerequisites are very important
[09:45:22] <_Tenchi_> ie, you have no business fucking with network virtualization if you dont know network fundamentals :)
[09:45:54] <CodeWar> yep :)
[09:46:17] <CodeWar> in my case touching AI when I didnt know what dhcp/ static ip address setup looked like
[09:46:22] <_Tenchi_> solaris 11 is such a huge change from solaris10 and prior versions it feels like i have to learn everything all over again
[09:46:36] <jelmd> http://download.oracle.com/docs/cd/E19963-01/html/821-1453/ipplan-1.html pp. explains, what you need

[21:52:05] *** ingenthr has joined #opensolaris
[21:52:13] <CodeWar> and HP didnt accuse them of being anti customer either :)
[21:56:01] <tsoome> well, the ms/redhat wont count for hp, but the cut off from oracle DB hurts them a lot, no point to buy those servers any more.
[21:57:49] <monsted> have they actually sold any itanics the last many years?
[21:58:37] <tsoome> i know at least one.
[21:58:46] <tsoome> one customer, i mean
[21:59:20] <tsoome> we lost deal to hp in some local bank - wasnt fair fight tho, because they had hp before and were preferring it.
[21:59:21] <CodeWar> I suppose theres money involved with service contracts
[21:59:40] <tsoome> and yes indeed, the service is the key
[21:59:48] <tsoome> same with sun gear
[22:00:22] <CodeWar> so the Oracle move was a neat sucker punch
[22:02:22] <tsoome> well, why not - the itanium is dead ended line for quite some years, and oracle got sparc, so they can be sure they can get all the big ones
[22:04:11] <CodeWar> by all means ..
[22:04:31] *** bobbyz_ has quit IRC
[22:04:53] <tsoome> altho many people do think the sparc will be the next one
[22:04:56] <CodeWar> though the Itanium is an interesting architecture .. that inspired a few more would love to hear from someboy thats used it as to why it failed
[22:05:30] <CodeWar> meaning drop oracle on SPARC?
[22:05:42] <tsoome> i think, at the end of the day, the reason is the same as it was for rock
[22:06:05] <CodeWar> dumb question but Rock != T3?
[22:06:09] <Stric> correct
[22:06:18] <Stric> afaik, itanic has real good oompf.. if you manage to get the Perfect Compiler..
[22:06:19] <tsoome> they failed to switch from x86 to itanium, x86 grew big and there is simple no point for itanium
[22:06:45] <Stric> and everything has to be compiled for the cpu you have, not just "generic itanic"
[22:06:49] <tsoome> and yea, the compiler is a lot to get perfomance from it.
[22:07:28] <CodeWar> meaning the idea of compiler doing processor front ends job is a dream that <a> never comes true or <b> comes true if you get the right version
[22:08:28] <Stric> intel has dropped support for itanium in their own compiler.
[22:08:32] <CodeWar> anyways fab technologies are advanced now 32nm is common? offloading OOO to compiler to save space doesnt make sense IMO
[22:10:37] <Stric> it's 3.1 billion transistors in the latest one, so "saving" isn't the word I'd use
[22:11:28] <monsted> itanium was extremely complicated in design, wasn't it?
[22:11:53] <Stric> less complicated, the compiler should do all the work
[22:12:02] <CodeWar> yep
[22:12:14] <Stric> (as a comparison, a quad core i7 has 0.7 billion transistors)
[22:12:59] <CodeWar> interesting .. 3.1 for a single socket dual core itanium?
[22:13:12] *** greendatacentre has joined #opensolaris
[22:13:44] <Stric> um. dual? why would anyone do a high performance dual core cpu now?
[22:14:03] <CodeWar> I m guessing most Itaniums would be from 4/5 years back
[22:14:13] <greendatacentre> anyone out there setup Solaris 11 Express as a ZFS NAS?
[22:15:14] <CodeWar> I think the transistor count would be fair comparing to Nehalem Ex / SPARC /POWER (6/7) .. i7 is a desktop cpu
[22:16:53] <Stric> anyhoo.. now time for simpsons.
[22:17:48] <greendatacentre> I'm trying to put together a ZFS pool of SSD drives and wondered if anyone out there have tried to setup Solaris 11 Express as a NAS file server

[22:19:34] <tsoome> greendatacentre: how should that differ from opensolris, or OI, or nexenta or .... :P

[22:20:31] <CodeWar> L3
[22:21:20] *** darrenb has joined #opensolaris
[22:21:37] <greendatacentre> Do you recommend using nextenta for Solaris 11 Express NAS?
[22:22:10] <tsoome> no, just was pointing out they are all based on zfs.
[22:22:46] <greendatacentre> I know they are all ZFS, but I guess I was looking for an appliance (hands off) image of Solaris 11 Express, and looks like Nexenta is the only option right?

[23:33:10] <tsoome> i havent seen it in ipkg, it is separate install and sysv packages
[23:33:46] <greendatacentre> i read somewhere that Oracle is going to start charging for Sun Grid Engine so I'm just wondering if there was a opensolaris community version for clustering
[23:34:37] <hunter_> There's also torque/maui - but I hate it when *I* ask a question and people say "Do this other thing instead!" to I hesitate to post that.
[23:34:50] <tsoome> just to make sure, you need computing cluster?
[23:35:16] <greendatacentre> Yes just like Sun Grid Engine, 1 master and others are compute nodes
[23:35:17] <hunter_> greendatacentre: oracle going full commercial on sge is my understanding as well
[23:35:51] <tsoome> afaik there should be several grid options around
[23:36:02] <tsoome> opensource ones, i mean
[23:36:05] <greendatacentre> @hunter_ thats what I thought too, glad they aren't just abandoning it.
[23:36:33] <hunter_> greendatacentre: giving everything else going on with oracle, I predict thats next.
[23:36:47] <tsoome> too bad they havent managed to create more from grid engine tho...
[23:36:59] <hunter_> sun didn't know what to do with it either.
[23:37:48] <tsoome> apple is using their Xgrid with stuff like podcast service etc, to convert multimedia files
[23:37:58] <hunter_> working with torque/maui now I appreciate sge more
[23:38:22] <greendatacentre> i used it many moons ago for a semiconductor company, it was great. Beowulf is gone, now penguin computing is running with it, but there isn't really any good commercial grid computing products.
[23:38:28] <tsoome> my howme university is using sge as well, they seem to be pretty happy
[23:38:30] <hunter_> people make a ton of fun of apple, but they mostly know what they are doing. Sadly, the rest of our industry doesn't
[23:39:00] <hunter_> mostly might have been generous
[23:39:35] <tsoome> I have to admit I was quite amused when i did see about that podcast stuff they have done
[23:41:50] *** mavhc has quit IRC
[23:42:19] <hunter_> I wish I could hook lightroom up to an SGE setup. I'd buy a bunch of mac mini's for photo processing.
[23:43:38] <tsoome> well, as long as you have the processing software installed in every worker, and its scriptable, it shouldnt be too big issue
[23:44:00] <hunter_> lightroom is many things, but not really scriptable.
[23:44:07] <tsoome> :)
[23:44:24] *** deet has joined #opensolaris
[23:44:34] <hunter_> actaully, forget that - I just wish lightroom would use all 8 cores in my mac pro to full usage.
[23:45:05] <hunter_> They wrote it to NOT dominate the machine, but as a photog I often just want it to go as fast as possible. Fuck everything else on the box.
[23:46:11] *** hunter_ has quit IRC
[23:46:28] * deet gets confused which window is #opensolaris and which is #macintosh
[23:46:35] * Hedonista nods
[23:46:41] <deet> not that i mind!
[23:46:53] <Hedonista> cant they use something like cflags
[23:47:20] <deet> adobe has to roll everything their own
[23:47:42] <deet> so it can Suck The Same™ on every platform
[23:47:52] <Hedonista> oh thats funny
[23:48:29] *** mavhc has joined #opensolaris
[23:49:16] <Hedonista> right on time wife has dinner ready , bbl
[23:49:20] <hjf> i love lightroom
[23:49:27] <hjf> it maxes out my core2 duo
[23:49:35] <hjf> the computer shuts down - thermal protection
[23:49:48] <deet> ugh
[23:49:49] <tsoome> lol
[23:50:03] <hjf> last time i was processing some raws from my camera, the cpu hit 100C
[23:50:25] <deet> although maybe you should hit it with some canned air… i would think a computer should almost never go into thermal protection
[23:50:34] <tsoome> what computer?
[23:50:40] <hjf> hp dv2000
[23:50:58] <deet> oh crap, i just set up three of those for a client :/
[23:51:14] <tsoome> something to avoid:D
[23:51:16] <hjf> i took it apart, re applied grease (arctic silver 5) and lowered 20C
[23:51:27] <hjf> yes, hp dv2000 - kill it with fire
[23:51:32] <deet> bah
[23:51:46] <hjf> http://www.collegehumor.com/video:1943659
[23:52:17] <hjf> thats a vid that shows you how to clean the dv2000's fan
[23:52:34] <hjf> it took me 1h 30mins to do it. and it wasn't my first time
[23:55:04] *** hunter_ has joined #opensolaris
[23:55:10] <deet> haha hilarious
[23:56:57] <hjf> yeah,it was the only thing that kept me sane while i was working on that computer
[23:57:05] <hjf> in fact i bought it because it had an HDMI port
[23:57:31] <hjf> and after 1 year the system board broke (nvidia 8400M needed reballing)
[23:58:01] *** dijenerate has quit IRC
[23:58:19] <hjf> had it reballed - didn't work. i had to replace the system board. it wasn't in stock anymore, so they sent me one with intel graphics. nice, cooler... but no HDMI port. as a consolation I got an extra USB port tho
[23:58:43] <tsoome> eh...
[23:59:01] <hjf> umm this wasn't hp warranty
[23:59:24] <tsoome> well, im happy with my pick:)
[23:59:24] <hjf> the machine died 1 week before wty expired
[23:59:32] <hjf> the machine was bought in USA
[23:59:42] <hjf> but i dont live there, so ... no luck
