Can any of you tell me if it's possible to migrate a filesystem from one server to another (or from one LUN to another on the same server) and retain Volume Shadow Copies? I hit this little snag on accident when prepping for this change, and my initial research says you can't do this, but that seems completely insane so I'm hoping someone here has a better answer for me.

Can you go over Ethernet to the "NAS" appliance? If you have a gig connection you should be pulling upto 120MB/s

Does anyone have any recommendations for basic entry-level SANs or NASs that are dual controller, dual power supply, etc? Features like snapshots and data tiering don't matter so much, these would be used in very small environments. I have seen the Dell MD3200i thrown around as a suggestion. Any cheaper than that which are still recommendable?

If those are your options, pick rolling your own whitebox with ZFS (if you're good on *nix) or Lefthand if you're not.

I tried doing it across Ethernet with a drive connected to my desktop, but it seemed to cause some network troubles, not sure why, but then again I am not entirely even sure of the topology here in general. evil_bunnY posted:You're breaking your head over something that "management" can fix with a $50/mo broadband connection. Particulars of our location mean our options for internet are very, very limited. Currently we're paying ~$1000 for a wireless 30mb link. Also we'd have to upgrade the link at the remote site, unless the backup the data to a third location. I think I am just going to go the usb3 route for a few months, it's cheap and gets me where I need to be for now. I am just really wary of solutions like this after my last job where things half-done and half-working constantly bit us in the rear end. Thanks, I'll probably need SAN advice next year...

V3700 is a great little product, but be aware that it doesn't support any block-level remote mirroring like the V7000 does. Still, the use of 6 Gb SAS or 1 Gb Ethernet instead of 8 Gb FC or 10 Gb Ethernet does mean some reasonable (if not gigantic) cost savings over the V7000. If you decide to trick it out with FC cards and dual controllers, the price isn't vastly different from V7000, as one might expect.

Any cheaper than that which are still recommendable? What kind of IOPS and space requirements are you looking for? My old environment (that I still do consulting for) currently has two MD32220i each with a MD1220i added on. They have been rock solid and provide the performance as expected (for the number of spindles). Going with a cheaper solution (prosumer) like Synology or QNAP will drop out the redundancy features (single point of failure being the motherboard). That old environment also has 3x QNAP 1679 running. While they are cheap and perform well (filled with SSDs), they are going to fail one day, and when they do, they will fail hard. For some reason I cannot get that through their heads. Edit: If you are really scraping to get something cheap that isn't prosumer. You can get used Dell MD3220i units with disks on eBay with a Dell warranty. Then you can contact Dell and extend the warranty for your HW lifecycle. http://www.ebay.com/itm/Dell-MD3220...=item232ebbf5fd Moey fucked around with this message at 16:45 on Aug 28, 2013 |

Yeah, thanks for the further suggestions. There is no specific IOPs requirement and we don't need fancy features because this would be going into small environments where shared storage isn't currently being used, or the only way of getting it sold would be something pro-sumer like a QNAP or Synology. I am trying to avoid having anyone run their environment off one of those NASes with no redundancy features. We have ways of restoring from backup, but when you're talking about 2-5 TB and 4-5 VMs, I'd like to reduce the amount of times we are having to restore from backup in these environments.

Wicaeed posted:Small/Mid-Size storage time: So, quick follow-up to this: Following two meetings with EMC, it is clear that their storage product lineup goes faaaaaaarrr beyond anything Equallogic offers. Seriously, the Equallogic setup we are planning for right now comes off as a simple DAS array compared to the offerings EMC has. Storage tiering with multiple disk types on a single shelf is extremely attractive to us, so much so that we actually have a budget in the 50,000 range now for EMC  The fact that our Dept VP and Manager are both on board with this speaks greatly. Looks like we might have EMC coming our way soon!

Also helps to be near the end of the quarter or year. Triply helps if the sales guy is having trouble meeting his numbers and needs the sale... Plus if you trade in your equallogic you can get some credit for that. Potentially even more credit if the sales guy thinks he's getting a big win in pulling out other vendors gear.

A question to those guys who have ZFS based systems in production, what are you using for your ZIL and L2ARC SSD acceleration? Obviously nothing with the words O, C or Z in the product description.

The premier drive for ZIL is the STEC ZeusRAM. It's an 8 GB RAM Disk that uses a supercap to back up to an integrated SSD in case of power failure. It's very, very fast and quite expensive -- $2k+ edit: RAM is really cheap. Buy lots for ARC and skip the L2ARC. KS fucked around with this message at 21:53 on Aug 30, 2013 |

It's very, very fast and quite expensive -- $2k+ Thanks for that - I also found the DDRdrive X1 (https://www.ddrdrive.com) as a PCI-E alternative to the ZeusRAM. Will have a look at both for the ZIL! From what I've read it doesn't seem to be a good idea to put it on NAND based devices, but go DRAM all the way.

This isn't exactly enterprise storage but today I got a new Netgear ReadyNAS 316. I've used ReadyNAS devices in the past and found them to be annoyingly finicky if not completely broken. However Netgear have really gotten their act together and the 316 is fantastic (Especially the GUI, really slick). I could definitely see myself recommending it for SOHO/SMB.

Waiting for a VNX2 can work if you don't mind adding to the timelines - the quotes will have to be redone (may go up or down in price, who knows) and there may be a delay getting it to you due to the usual rush.

If you already planned on buying a 5300, why not buy one at a fire sale price? If you need something bigger, I was told that EMC is currently taking STEEP cuts on the new 5400 since the 5200 won't be done available for two or three months. I wish MCx would come to the existing VNX line. We see a drop of maybe 1-2 pings when a LUN is trespassed and I'm hoping the new architecture would fix that. Totally kills me that it's a forklift upgrade. I'm not even sure they'll let us keep our existing shelves right now, which I think is a Q4 / Q1 next year approval. I got a Pure Storage briefing a month ago, and man, it's like seeing the future compared to what EMC is doing. Non-disruptive storage controller upgrades. (Yeah, you lose a path but better than a total outage.) Too bad they've got zero features right now. No FCoE, no array based replication, no iSCSI, etc. VSPEX looks to me like EMC is preparing for the imminent collapse of VCE.

I just had EMC re-quote me a VNX2 5400 instead of the 5300 because as El_Matarife says, EMC is offering pretty steep discounts on the 5400 in low end configurations until the end of the quarter to avoid bleeding customers until the 5200 comes out. Without any discounts I was told the price on the 5400 was ~15% higher than the 5300.

Given that the 5400 is the equivalent of a 5500, that's a good deal. Twice the iSCSI / FC ports, twice the drives. If you're worried about expansion on the 5300, you just solved that problem.
