In that case it's possible our customer pasted us the wrong bit of the log - they're saying that discs are actually dropping out of arrays. On these, they set them up as individual RAID 0 per disc because the 9260 doesn't support JBOD exporting by default. They then use these in linux softraid.

SCSI resets aren't in themselves very useful for troubleshooting. They can mean bad things are happening like errors on the bus or a specific device, but they are also used in some instances where there are no errors. I'd call your hardware vendor and engage their support if you're seeing issues.

How does a PS4100E-High Capacity-24TB compare to a NetApp 2240 or a Nimble CS220? Do they have good management software and how is their snapshot ability compared to NetApp and Nimble? I noticed that the quick ship price for the PS4100E is $25k, while Nimble and NetApp are still hovering around $34k. I'm starting to be more forceful with NetApp, since so far they haven't budged on their price and included the complete software bundle. I like what I saw from their equipment, but so far I haven't seen much effort from them to accomodate us.

Do you mean an Equallogic PS4100E? If so, I have experience with their arrays and management software, but not with NetApp or Nimble. I will say that the E means it is using SATA (or 7.2k SAS, whatever you want to call it). Just make sure you are getting enough IOPS. On the management side, I love their software. It really could not be any easier to use. Their arrays are entirely "virtual storage." You basically say, I want X amount of disks in RAID50 and Y amount in RAID10, or I want all disks in RAID10, and it does the rest. When you make a LUN it is basically like making a partition. The array does all the work and will automatically balance it all in the best way it can. SANHQ is software that comes with, just like everything else Equallogic, and allows for a very easy and granular look at what is going on. I don't know about NetApp or Nimble, but it completely blows EMC's Unisphere Analyzer out of the water. Snapshots and replication are extremely easy to set up. MPIO is also very easy. I absolutely loved my Equallogic array. The only issue was you had to buy the unit completely filled, and if you wanted to add more IOPS or Storage you had to add a whole new array. In my company that is difficult because they would just put it off over and over again. With my VNX I can say "this new project requires X space and Y IOPs, we need to add Z disks." You cannot get that granular with Equallogic. If you do not have a dedicated storage admin or time to mess around with your SAN all day, I cannot recommend Equallogic enough.

As far as how their snap shots work, are you able to browse them and recover individual files or do you need to mount the snapshot in order to retrieve the file? With NetApp standing pat on pricing at the moment, I need to start seriously considering some other options. I'd like NetApp to work out, but they need to start making some concessions on their end to make it a more fair deal. I hate getting stuck doing negotiations, but with a small IT department, I guess that's the reality of the situation.

Yeah, I was in the same situation when we researched SANs the past 2 rounds of replacements. It was months of researching and getting quotes and I had tons of other stuff to do. The first time we stuck with Equallogic and bought 2 new units, this last time we went with EMC and I regret it quite a bit. Unless something changed very recently, you need to mount the snapshot on a server and recover the file. I think this is the same with anything serving up iSCSI. I'm not sure, but I think you only see that when you are doing NAS functions from the SAN. Equallogic does have a NAS box that goes on top of their block stuff, but I have no experience with that. When we were negotiating with Equallogic, NetApp, and LeftHand 3 years ago or so, NetApp was the highest by far and they wouldn't budge at all.

It had to be mounted to a host that understands the filesystem on the lun snapshot. To the array its just a bunch of bloks in a container. NetApp can expose files from a snapshot directly when it's an nfs or CIFS share because those are WAFL files.

It looks like NetApp and CDW are starting to provide some solutions on price. It looks like they included a $5,000 installation fee, which I'll see if they can waive or heavily discount, otherwise I don't see why we couldn't set it up ourselves. They also mentioned including some training vouchers, so I assume that we could use those or their general support for any questions during the setup. That would bring us down from $34k to $29k and if we hold off on some virtualization specific software, which we probably aren't going to need right away, then that would bring it down to $26k. That being said, I would like to just get all of the software included, but I need to wait and see how much they budge.

All inclusive pricing doesn't make sense when your product range is that broad as you end up heavily penalizing customers who don't use half of what they end up paying for. Equallogic is relatively niche, by comparison, which means they can price things differently.

It's cool that you're happy with your storage and equallogic is pretty cool from everything I've heard but there's nothing wrong with licensing certain features or bundles of features, at extra cost as long as the cost is reasonable. That revenue pays the teams who develop and maintain those features. It also allows NetApp, for instance, to be cost competitive with vendors who don't match their full feature set.

I found the docs are pretty clear and easy to follow if you want to do everything through CLI like a boss.

There is a pretty big difference in what NetApp and EMC can offer and what Equallogic can offer. But, if you only need the smaller feature set, to me the choice with Equallogic is clear.

They've got a good product from everything I've seen, but they're also competing in small market. The last numbers I saw had iSCSI as around 15% of the total networked storage market. iSCSI doesn't yet have nearly the penetration that FC or NFS do, especially in the high end. It wasn't even worth charting the iSCSI market 10 years ago. It's growing quickly, but still small, and less competitive. szlevi posted:management-monitoring-pricing If this was really at the top of most customer's lists then EMC wouldn't have more market share than the next 3 storage companies combined, and they wouldn't be growing it quarter after quarter. Equallogic is a good fit for a certain type of business but it's really lacking for many others. Which is why Dell bought Compellant (which uses a traditional licensing model where you pay for the features you want).

We're most likely going to be getting Compellent for our main server room on campus, but I'm thinking an Equallogic would be pretty good for another department we support, I guess you'd call it a branch office. Unless Compellent offers something redundant in the 15-20 TB range for same amount of money as Equallogic.

Compellent is absolutely terrible. We were given a unit due to the amount of business we do with Dell, and it's a pile of junk. Controller crashes that they can't explain, blaming issues on firmware being out of date even when the array says there are no updates (you, literally, have to call to find out if there are updates and to get them to release them to you, but in the meantime if you do "Check for Updates" your array will tell you it is all up to date), Copilot support rebooting the wrong controller when 1 is down and bringing your entire storage down, Copilot support blaming performance issues on using thin-provisioned VMDKs, Copilot support saying a massive performance issue is due to number of disks (we're talking each disk getting like 10 iops, yes 10 not 100). Do never buy.

I'm hoping someone can help me out with a problem we're having here at work. I'm not a Windows server admin, nor am I a server hardware expert. We have a VTrak e610f enclosure hooked up to a Windows 2008 server by Fibre Channel (LSI7204EP). fcinfo sees the fibre channel card, LSI's fibre channel utility can see and query the enclosure. What's confounding us, however, is VDS. The service is installed, but the MMC/diskraid.exe report that it cannot communicate with it and mentions a hardware provider. I've been searching for a while now and see plenty of mention of iSCSI, but nothing specific about FC. I tried to follow Promises' instructions and installed their PerfectPath software, but it hasn't solved the problem. The drive shows up as one solid block of storage in Disk Management, but we were hoping to be able to divvy up the storage somewhat. Can anybody point me in the right direction? Should I have said VDS Hardware Provider?

We have a 2050 that we plan to retire, but want to reuse it's disk shelves. Before we can retire the 2050, we need to put our 3140 in it's place. We have a 3240 that will take the place of the existing 3140. When we replace the 2050 with the 3140 we will take all of the 3140's shelves with us. The problem is that we want to use the existing 2050 disk shelves with our 3240 before we replace the 2050. What we did was purchase two shelves on ebay that we will temporarily use with the 2050. I have put the two shelves into play, and have 28 disks sitting empty. What is the best way to move my data to these shelves? Is it to create two new aggregates and snapmirror the data from the old shelves to the new ones? Or is it to use the disk replace command to move the aggregate one disk at a time? We plan to sell these shelves on ebay after we are done, which is why we have to play musical data.

three posted:Compellent is absolutely terrible. We were given a unit due to the amount of business we do with Dell, and it's a pile of junk. That's quite odd... What series controller(s)? What version of Storage Center are you running? I've had nothing but extremely good experiences with Copilot, and never had a problem getting the help I need. Yes, it's a little annoying that you have to call and open a case to update the firmware/Storage Center software. But it's nice that when you do, they remote login and do a health check before releasing the software. If you set up an alert in Knowledge Center, you'll get an email notifying you whenever there's a new version, and then you can call in and start the case. I've had mine about a year (SC40 controllers, on 5.5.6 OS right now) running VMware and Oracle Database backends. I have plenty of thin-provisioned VMDKs that were storage-vmotioned over from an old array, but I don't see problems with that. I've never had my controllers lock up, and never had Copilot reboot either of my controllers. I routinely hit 300-600MB/sec and 11K IOPS during busy times, with latency staying below 4ms. Don't you get a survey link every time you open a case? If you're really having that many issues, I'd give a negative survey response and wait for the calls to come in. I rated something negatively the first time a Dell contractor came out to replace a part, and had never worked on any of the Compellent gear. He wasted over an hour reading manuals for a cache card replacement. I got a call from a manager asking for more details a few hours after I submitted the survey. The next time I had someone out (their lab had identified a problem in some limited cases with Emulex 8Gb FC cards, so they proactively replaced them with Qlogic 8Gb FC cards) the same guy came out. He said that he got a call asking him to schedule some Compellent training at Dell's expense after the last time he was out, and was a lot more comfortable working on them now. I've been nothing but pleased so far.

Previous arrays were HP EVAs, just retired my EVA 4000, still have an EVA 4400 in production. My job doesn't have enough people to have a dedicated SAN Admin, and I wouldn't say that I've got a particularly high-end deployment, but it's not really low end either. The fact that SAN is just one of many things I do (VMware, AIX, Linux, Network) is what pushed me toward the Compellent. It's easy enough to configure and use without having to dedicate exclusively to that. As for VAAI, Storage Center 6.0 supports Full Copy Offload and Hardware Assisted Locking too. Meh, I'm sorry you've had bad luck with it. Since you got it for free and hate it, if you wanna send it my way, I'm sure I could figure out something to do with it.
