I have a dell 2950 w/ 6) 2TB drives. Any thoughts or suggestions?[03:31:37] *** myers has quit IRC[03:31:47] <Teknix> banditti: what do you ultimately want to do with it?[03:32:07] <banditti> I want a big NAS box to use with my vm environment[03:32:16] <banditti> NFS, sorry[03:32:25] <Andys^> use RAID10[03:32:33] <Teknix> are you using NCP or NexentaStor?[03:32:44] <banditti> I am not using anything yet.[03:32:55] <banditti> I have used openfiler before and don't really like it.[03:33:16] <Teknix> do you want a commercially supported product?[03:33:26] <banditti> Andys^, I don't want to kill 6TB of space with RAID10[03:33:35] <banditti> I don't really want to pay, no[03:33:45] <Teknix> web interface or cli person?[03:34:36] <banditti> I would prefer GUI, but can do CLI if there is functionality I don't get[03:34:47] <Teknix> http://www.nexentastor.org/projects/site/wiki/CommunityEdition[03:35:23] <banditti> don't I need a small drive or two for the OS?[03:35:53] <Teknix> ideally you want two small drives to mirror for the OS[03:36:21] <banditti> does it use the whole drive or can it be partitions on drives?[03:36:47] <Andys^> whole drive[03:37:12] <banditti> thumb drives?[03:37:13] <Teknix> you might be able to hack it to use partitions, but it would be non-trivial[03:37:19] <Teknix> you could install on mirrored thumb drives[03:37:26] <Teknix> there are downsides to that however[03:37:55] <banditti> The servers only have (6) drive bays and I have (6) 2TB drives. I hate to lose the space[03:38:07] <banditti> what are the downsides?[03:38:07] <Teknix> sure, that's always a problem[03:38:19] <Andys^> downsides are: thumb drives can be bumped out, so a bit unreliable[03:38:34] <banditti> it is in a colo, so I am not too worried.[03:38:36] <Andys^> and RAID10 gives you higher random IO performance which VM storage really needs[03:38:41] <Teknix> in my experience, the boot time is very slow, and you'd need to minimize writes to the filesystem. That means putting swap, logs, etc. somewhere else[03:38:46] <Andys^> hahah :) never had a power cable bumped out in colo?[03:39:05] <Teknix> does the 2950 have an internal usb port?[03:39:09] <Teknix> or two?[03:39:09] <banditti> I was thinking of a PCIe ssd[03:39:14] <banditti> no internal usb[03:39:36] <Teknix> if you go the usb route, find two of the micro/short usb keys so they don't stick out[03:39:50] <banditti> If I did mirrored USB for OS, pcie SSD for logs, swap, etc and (6) 2tb drives for data[03:39:58] <Teknix> you'll want at least 16gb though[03:40:08] <Teknix> which pcie were you thinking of?[03:40:12] <banditti> 16gb usb or ssd?[03:40:24] <banditti> I don't know, recommendations?[03:40:40] <Teknix> 16gb usb, so you have room for apt-clone (multiple boot environments that you can rollback to in the event of failed upgrades, etc.)[03:40:59] <Teknix> is the 2950 half height or can it support full height cards?[03:41:07] <Teknix> and what is your budget[03:42:12] <banditti> full height[03:42:49] <banditti> I really don't want to spend too much. what are you thinking?[03:43:03] <banditti> How big do they need to be? Will it be worth it?[03:43:21] *** JagWaugh has joined ##nexenta[03:43:25] <Teknix> well, the ddrdrive X1 is highly rated, but may be overkill for what you want. You only need a device that is half the size of your available memory[03:43:31] <banditti> the 2950's have perc6i cards, I probably need to rip those out and use SAS JBOD right?[03:43:48] <Teknix> if they support JBOD mode then you could use them[03:44:07] <Teknix> the LSI cards work best[03:44:25] <Teknix> the only pci-e cards I know of that work well are going to run you around $1K[03:44:28] <banditti> I think perc is rebranded lsi[03:44:48] <banditti> not in the budget![03:46:06] <Teknix> actually, the ocz revodrive x2 appears to be around half that, but I have no personal experience with it[03:46:28] <Teknix> but for write cache you want SLC based stuff[03:46:37] <Teknix> or NVRAM with battery backup[03:47:00] <Teknix> another option is to give up one drive bay and put in an SSD[03:47:29] *** JagWaugh has quit IRC[03:50:34] <Teknix> that is MLC based[03:50:43] <Teknix> which means when using it for write cache, it will wear out quickly[03:51:27] <Teknix> you are facing the good, fast, cheap rule. Pick any two[03:54:30] <Teknix> recommendations for the perc6i are to present the OS with raid0 luns[03:54:51] <Teknix> or set it to a JBOD mode if the BIOS gives you that option[03:57:14] <banditti> hmmm, well thank you for the insight, it has been very helpful[03:57:29] <banditti> how much difference will the ssd make?[03:57:43] <Teknix> that really depends on the type of load your VMs will present to the system[03:57:54] <Teknix> if they are very lightly used you may notice little improvement[03:58:25] <Teknix> if they do heavy I/O, which over NFS they will since it will be all O_SYNC (assuming VMware here), then you will see a significant benefit[03:59:02] <Teknix> there is a very evil way around this, but you would really need to understand the consequences and I'm not about to suggest it[03:59:42] <banditti> which is?[04:00:18] <Teknix> if you can't come up with a suitable write cache device and the performance is poor, you can come back and ask me ;)[04:00:58] <Teknix> my suggestion is to try it first[04:01:20] <Teknix> if you're trying to run a business off this, you want a suitable write cache device[04:01:39] <banditti> slc's are 5K[04:01:46] <Teknix> if this is for hobby/friends/nothing terribly important, then you might be able to get away with something else[04:04:25] <Teknix> the intel x25-e is a reasonably priced SSD.. 32GB would be more than sufficient[04:04:37] *** myers has joined ##nexenta[04:05:33] <banditti> If i wanted to lose a slot[04:05:40] <banditti> I mean 2tb[04:05:52] <Teknix> everything has tradeoffs[04:05:59] <banditti> ZFS is a RAID what?[04:06:14] <kdavy> it's a RAID anything you want[04:07:02] <kdavy> you could put all six drives in a single mirror if you wanted, or run them all as raid0 without redundancy[04:07:14] <kdavy> or anything inbetween - raid5, raid6, raid7[04:07:51] <banditti> Raidz2 would be raid6 right?[04:07:58] <kdavy> correct[04:08:15] <banditti> essentually, I would get 5.5TB usable out of (5) 2TB drives[04:08:49] <kdavy> 6Tb usable - well, 5.5 considering drive manufacturers lie about drive size[04:08:51] <Teknix> a 2TB drive will format to around 1.8TB of usable space, and in a raidz2 vdev you'd lose two drives worth of space[04:09:12] <banditti> do i have to do anything special on the install for the ssd part?[04:09:22] <kdavy> no[04:09:41] <kdavy> you can even add ssd after you make the raid volume[04:10:25] <Teknix> banditti: good luck, I'm away for awhile[04:10:38] <banditti> Thanks again[04:10:43] <kdavy> Teknix: i'll take over :-P[04:11:12] <Teknix> kdavy: yes, thanks :)[04:14:08] <banditti> something like that?[04:15:44] <kdavy> banditti: yeah, i use these. good for write cache[04:16:31] <kdavy> wtf... this must be a pricing mistake - http://www.compuvest.com/Search.jsp?Search=SSDSA2SH064G101&advsite=froogle&sku=602000665-02&dp=2:ITX:41975:0:0:[04:16:48] <kdavy> 64Gb for 10% more than the cost of a 32Gb[04:17:42] <banditti> Sweet![04:17:54] <banditti> what about this for mirrored OS?[04:18:10] <kdavy> banditti: you pasted the same link[04:19:01] <kdavy> for a mirrored OS, any two small 7200rpm hdd's will do[04:19:24] <kdavy> (i use laptop drives in production for one of my units, 160Gb WD's)[04:20:15] *** myers has quit IRC[04:28:42] *** myers has joined ##nexenta[04:29:43] *** laserbled has quit IRC[04:31:43] *** myers has quit IRC[04:49:37] *** POloser has joined ##nexenta[05:01:28] *** alhazred has joined ##nexenta[05:03:44] *** alhazred has quit IRC[05:04:41] <banditti> sorry, had to put the kids down[05:05:09] <kdavy> banditti: sure, those will work. just don't pull both of them out at once[05:05:25] <banditti> Nope![05:05:42] <kdavy> and i'd advise 32Gb - 16 might run out of space after several upgrades[05:05:57] <Andys^> i run a nexenta box on 8gb[05:06:15] <banditti> I wish there was a decent alternative to losing one of my drive bays to SSD[05:06:39] <Andys^> SSDs are small[05:06:49] <Andys^> just shove it somewhere in the chassis with some cable ties ;)[05:07:23] <banditti> possibly[05:07:55] <Andys^> Filesystem size used avail capacity Mounted on[05:07:59] <Andys^> syspool/rootfs-nmu-001 7.3G 929M 4.7G 17% /[05:08:42] <Andys^> well, there's about 5GB free.not really enough room for a kernel dump though. but i'm not too worried.[05:08:50] <Andys^> btw you can enable compression and dedupe on root volumes.[05:08:56] <banditti> what about this for ssd?[05:11:31] <Andys^> banditti: btw, you *can* partition the root drives, but not with the nexenta installer.[05:12:05] <Andys^> i did it by installing nexenta onto one disk, then creating a new bootable partitioned disk on another drive, zfs send/receive the whole pool over to it[05:12:32] <Andys^> do the same partitioning to a 3rd drive, and zfs mirror the two new partitioned drives[05:12:47] <Andys^> took a long time to find the right commands to get that done :)[05:21:20] <banditti> more work than I want to do![05:22:33] <Andys^> i reckon if you're running off a decent SSD You probably only need one[05:22:41] <Andys^> Intel SSDs are very reliable[05:23:27] <kdavy> banditti: Transcend will be way too slow[05:23:42] <kdavy> (as a ZIL that is)[05:28:02] <banditti> I am with you[05:28:38] <banditti> would you do something like this?[05:29:00] <kdavy> fuck no[05:29:19] <banditti> or this with warranty[05:29:40] <banditti> I didn't think so either. hmmmm, have to spend money I guess[05:30:06] <kdavy> still no. not unless i see the SMART dump from the actual drive showing the amount of data written to it over its lifetime[05:30:25] <banditti> I am with you![05:30:25] *** kart_ has joined ##nexenta[05:30:52] <kdavy> also it's a G1. you want G2 at the very least[05:31:24] <kdavy> G1 has issues even firmware can't fix[05:31:37] <banditti> how do you tell g1 from g2?[05:31:55] <kdavy> part number[05:32:01] <kdavy> SSDSA2SH032_G1_GN[05:32:51] <Andys^> the G1's not that bad :)[05:32:56] <Andys^> i'm using a bunch for L2ARC[05:33:39] <banditti> got it[05:33:41] <kdavy> Andys^: still, buying a used G1 now isn't good advice[05:34:12] <kdavy> a small Sandforce drive, even MLC, will probably be better, faster and cheaper[05:34:18] <kdavy> and just as reliable[05:35:44] <Andys^> yeah i wouldn't buy Used[05:36:03] <Andys^> Intel now make a 20GB SLC drive which is good value. fast for write IOPS and just enough space to boot off[05:36:06] <Andys^> its about the $100 mark[05:36:17] <banditti> So, use the PERC 6i for raid6 or let ZFS2 do it?[05:36:30] <kdavy> let zfs[05:36:31] <Andys^> ZFS[05:36:54] <banditti> I can't seem to verify if my PERC 6/i will do JBOD or I have to swap it out[05:39:32] <banditti> maybe the sas 6i/r is the way to go[05:42:58] <kdavy> nfc[05:44:11] <banditti> I will check tomorrow.[05:50:35] <banditti> I think I can stick a 2.5" ssd in my CDROM slot and use an external cd[05:56:15] *** ikarius has joined ##nexenta[05:56:41] <kdavy> banditti: that's what she said[06:05:56] <banditti> recommendations on a internal pcie sas controller[06:06:33] <kdavy> lsi 9200-8i or -16i or -24i[06:08:26] <Andys^> +1
