I'm having a serious gently caress EMC day. I just ran across a stupid bug in their sans. If you have a vmware host with an IQN that contains uppercase character(s) and you enable chap with the VNXe3300, the VNX will replace the uppercase characters with lowercase and the login from the ESX host will fail. Example of the failure case: ESX IQN: iqn.1998-01.com.vmware:NORTHSTAR-05ec8187 VNX IQN: iqn.1998-01.com.vmware:northstar-05ec8187 (never mind that I pasted the ESX IQN directly in to the VNX, the VNX still did the replacement.) Example of a working case: ESX IQN: iqn.1998-01.com.vmware:northstar-05ec8187 (had to enter this manually into the ESX SWISCSI adapter.) VNX IQN: iqn.1998-01.com.vmware:northstar-05ec8187 I think this is likely a bug in the UI of the VNXe but I'm not sure.

The offending version appears to be 2.2.0.17142 and the bug was fixed in the subsequent version 2.2.0.17384. The ways to fix it in place are: 1) Change all of your IQN names to only include lowercase letters. 2) If you don't want to do that, you would need to have Engineering log into the box to perform some back end magic (seemingly to hand edit the IQN names in the configuration) to allow for the uppercase IQN's. They would potentially need to log back in at a later time again if the names got changed back to lower case in the config.

ZombieReagan posted:Ok, that's some helpful information - thanks. The storage virtualization itself is nice for a way to help simplify some of the more mundane storage work, but replication is that part that I'll have to use in order to convince upper management to let me spend money on it. I don't know that we NEED the kind of features VPLEX has, but it certainly wouldn't be a bad thing. It'll all come down to cost, but this sort of summary helps me keep an open mind about those products. Thanks again. In many ways it's important to remember that storage virtualization doesn't really make anything more simple. Marketing says it is simple. In practice it is adding another layer in between your storage and users at significant cost too. VPLEX. SVC, incipient and such are not cheap. Arrays these days are getting easier and easier to manage at scale. Arrays such as the XIV are a prime example. Additional features in arrays have made things easier (VMware plugins, pools of storage, etc.) Data migration is the exception, it's a *lot* easier to retire an old array if you're using something like SVC. migrations are one of the few times when all departments have to work together and it's hated. Storage virtualization can make this process a lot less of a chore. A lot of EMC customers used Powerpath migration enabler, which basically allows for the data to be moved without down time but also without any virtualization layer. I'd ignore any 'simple' reasoning and just focus on what it will give your business. Migrations without downtime is desirable and valuable to the business. Making your life easier is probably about 40 items down the list

adorai posted:That still doesn't help with a LUN. When we pulled the trigger on replacing our netapp 3140 with a 3240 (so we could use the 3140 at our DR site) me and one of the guys on my team worked about 65 hours each that week. Not terrible, but still a lot more than normal. Our end users were mostly unaffected, though we did have a lun go offline on our mail server the next week because autogrowth was disabled. Datamotion for vFiler is intended to help solve this problem. You can non-disruptively move vFilers between arrays. This is also one of the big selling points of cluster mode since you can move anything anywhere to phase in or phase out new equipment easily. If your volume manager supports it, and most modern OSes do, you can also create a mirrored raid group with the new storage as one half of the mirror, then break it off after it has silvered. That's how I've done most of the ZFS and Veritas migrations I've done. YOLOsubmarine fucked around with this message at 03:16 on Sep 26, 2012 |

Is it cool to ask about SMB storage here? We're looking to move into NAS here - small environment but we need something more robust than the "prosumer" units. My initial goal is ~1TB for file storage and potentially up to 5 iSCSI targets (VM dev environment, additional dedicated storage on individual servers). I want an 8-bay unit to accommodate potential growth. Budget is ~$5000 (including disks), which pretty much keeps me out of even the entry-level netapp stuff. Right now it looks like my best option is a QNAP TS-879U. Is there any serious competitors in that price range? Also, SAS disks - any recommendations for brands/models? Looking at the 300GB range.

My personal opinion is that unless you need HA, ZFS on BSD will be better than most SMB-oriented NAS units, especially with big old SATA drives. This also means you can build stupid fast pools with relatively cheap SSDs. It's fun to saturate 10GBE links with <$1k worth of flash.

Does anyone have any experience with Partners Data? http://www.partnersdata.com/cgi-bin/productinfo?division=systems&id=761 Another department here has been using them for a while now, and they say they're pretty happy with them. They're pricier than the cheap QNAP stuff I was looking at, but still cheaper than Dell.

Every single thing you ask is a really bad idea, and you must be a glutton for punishment, because you don't listen to a single thing from people who do this poo poo for a living and actually know what they're talking about, and you keep coming back here to ask ridiculous questions about Xserve RAIDs and off-brand SANs. I have no problem with people thinking my questions are ridiculous. I'm trying to learn and gather information. From previous replies in this thread I went and tested some iSCSI setups. Also, after speaking with other people that "do this poo poo for a living", they recommend Partners Data due to the reliability of hardware and level of support they received. If it's a bad idea, I would like to know why.

Xenomorph posted:I have no problem with people thinking my questions are ridiculous. I'm trying to learn and gather information. Partners Data is just a reseller, not a vendor. So who actually makes the SAN you linked? What software is running on it to provide storage services? What is their largest deployment? Can they provide a few references to customers who have used the product for some time? Can you find any independent reviews of the product? Are there any independent benchmarks like SPC or SPEC to validate the performance claims? Is there an active community around the product that can provide insight into the day to day challenges? Can you find a single post anywhere on the internet from an actual user of the product discussing their experiences? I mean, if you google "Surfraid Triton" you get pages and pages of links back to the product info page and one guy asking if anyone has ever used it for PostGres on a forum, a question to which no one responds. That is bad. If there is no useful information on a product anywhere online then you should probably elect not to put business critical data on it. There are a ton of established storage vendors to choose from and some even have fairly cheap offerings like Dell with the PowerVault line. Talk to one of them. At least you'll know what you're getting.

If you're really that tight and your company doesn't care about good support, you should build a disk array yourself or hire someone to build it to get the best price. If you want to someone else to be responsible for the risk of having a SAN fail for your company, then you buy from one of the vendors that people in this thread talk about. If some guy recommends Partners Data, find out how many times they've had to fix it. "Works great right now" from some guy is not enough to define storage strategy.

We have good experiences with our Compellents and the support organization, but we also have a crackerjack reseller who helps the relationship. I'd be a little concerned about working for Dell, just because they're now so huge and still integrating Compellent, EqualLogic and Force10. There are also some weird decisions lately, for example their NAS head, the FS8600, is only just being released and will only support Fibre Channel, and not ISCSI. But overall I like their storage roadmap and I think they're going in the right direction. If you want to learn about data progression, replays and so forth, I'd just poke around their site, e.g. here. "Dell Compellent Best Practices" may turn up some good documents, if you don't have access to Copilot there may be I guess I'd prefer to go work for the EqualLogic team. There's also always Partners Data, who's really coming up in the world.
