Anybody familiar with Scale Computing? They caught our eye because they were originally in the financial market, which is what we do (even though they failed at it). Their system starts with 3 1U units, either 1TB, 2TB, or 4TB per unit, and then you can expand 1U at a time, mixing and matching pur-U capacities.

Perhaps it would be more useful for me to explain my needs  We're a small company (20 users) and we currently have about 2.5TB of data spread across an EMC AX-100 and local storage. We'd like to replace the AX-100 with something that starts at around 6TB and is greatly and cheaply expandable (there's a very good change that our storage needs will jump to 50TB in a year or two). We don't like the EMC because EMC was quick to end-of-life it and we're bitter that we can just put 1TB drives in it and call it a day. Scale Computing/Isilon was attractive because it's so expandable and doesn't require too much management, but Scale Computing is very small and that's scary, and Isilon was too expensive (the sweet spot to start at was 18TB, and that was 40 grand from Isilon). I'll try to get an idea of cost from LeftHand, but is there anything else that may work for us better?

What do folks use for backup to disk storage? Currently we have a Buffalo Terastation at each site. Other than not supporting SNMP monitoring (seriously Buffalo?) they've met our needs. Is this a bad idea or acceptable? I will need to increase our B2D capacity and will probably just get a second NAS, unless that's a bad idea for some reason.

I have a new EMC AX4 iSCSI array in place and it seems quite a bit slower than I think it should be. Is there a reliable way to benchmark its performance and any statistics for similar devices that I can compare it to? I've tried googling around but I can't find any "here is what speed you should expect with this iSCSI array" information.

oblomov posted:You really need to provide some more info. What's slow exactly (i.e. whats the throughput you are getting)? Which disks do you have in there? How is it connected (how many ports, port speeds, what switch, switch config, jumbo frames, etc...)? What is it connected to (what is the server hardware, OS, application)? Sorry, I didn't provide information because I wanted to run a benchmarking test to see if the speeds are really slower than they should be before I ask for more help. I was getting 20-30MB/s read and write when copying files in either direction. I found CrystalDiskMark and here's what I get: Sequential throughput: about 30MB/s write and read. Random 512k blocks: 0.8 - 1MB/s read, 28-30MB/s write. Random 4k blocks: 7MB/s read, 2MB/s write It's an iSCSI AX4. The array I'm dealing with is a 7-disk RAID 5 with 1TB SATA drives (12 total disks, 4 SAS drives for the Flare software, 7 disks in RAID, one hot spare). The AX4 has dual controllers, so it has a total of 4 gigabit iSCSI ports. iSCSI is on its own switch, a ProCurve 1810-24g, gigabit managed switch. Jumbo frames is currently off. I tested from two servers, one 2008 R2, one 2003 R2. Both use the Microsoft initiator over one regular gigabit ethernet adapter (not an HBA). EMC PowerPath is installed on both servers. I realize there are a few things keeping me from optimal speed: SATA drives, no jumbo frames, and no HBAs. I still feel like the speeds are lower than they should be, even considering those factors. Maybe my expectations are too high?

The application that the server is for has been installed, and it's hanging whenever you do anything that involves reading files from the SAN.

Syano posted:Is there any particular reason jumbo frames are off? We pulled a cx3-10 array off a Cisco and put it on a Dell and the performance was absolutely abysmal until we turned jumbo frames on. I didnt realize how much of a difference the two switches would make until I saw it with my own two eyes. Not sure if the procurve is your culprit but its worth a shot if you can turn jumbo frames on. The contractor who set up the SAN didn't enable them, and I haven't been able to schedule downtime to enable them (I'm under the impression that the AX4 will reset connections when changing MTU size). It's certainly something that should be done, but I don't know if it's the entire cause of the poor performance. I'll see what EMC says.

Anybody have experience with Promise VessRAID units? I know it's super low-end, but it's just going to be our backup-to-disk target/old files archive. My concern with the unit is that it's been synchronizing the 6TB array for almost 23 hours now, and it's at 79%. If I add another array down the road and it takes a day to synchronize, the existing array better be usable.

Wompa164 posted:I'm not sure if this is the appropriate place to post this, but heregoes. Yeah, this is a little weird. But, probably the easiest thing to do would be to buy one on eBay, then when you're done with it, sell it on eBay. It's not like it'll depreciate that fast, so if you're patient, you can probably turn a small profit. Or just buy 12TB of hard drives or something.

Every time I have to use that shitfest and get one of those "Survey's on behalf of EMC" emails I fill it out so god damned hard  I'm not normally one for surveys, but somehow rating everything about Powerlink as absolutely atrocious helps me get through my day.

Syano posted:I have a customer that ordered a expansion shelf in for an AX4 and asked me to put it in. I have zero experience with emc much less the clariion line and it looks like I need some sort of login to even get to the documentation. Is adding an expansion shelf a pretty easy prospect? Is it hot add? Or am I going to have to spin down the array? It's pretty simple, just pay attention to the direction of the arrows on the interconnect ports. You can do it hot, but maybe after hours just in case. It's funny, they'll let you rack and connect a new tray, and don't provide any documentation to do it, but they insist on sending someone out to do a firmware upgrade.

ehzorg posted:Hey good storage peoples, advise me please. You know you can say gently caress and poo poo around here, right? Your budget is a bit tight, but there's no harm in calling up the vendors and seeing what they'll do. If they know your budget and needs, and feel like they can meet them, they'll come visit and give you a demo. Have a higher-up sit in on some demos so the vendors can tell them what an absolute god-damned nightmare shitpile you're sitting on right now. I feel like Dell and EMC might be able to offer you something at that price (but they'll push for a little more).

demonachizer posted:Could someone give me some quick advice on how to proceed with converting a file server to a VM? Currently we are consolidating about 4-5 different file servers into a single VM. When deploying it, I am thinking of keeping the disk space of the VM small and presenting the storage to the server rather than provisioning a huge VMDK. There's no good reason not to move the file store to a VMDK, other than the work it entails (unless it's hundreds of terabytes or something). Once it's moved, though, you'll be in a more flexible position to move it, tier it, snapshot it, etc. You should keep the OS on a separate VMDK regardless. If that backup scheme works for you, you might as well keep it going.
