Just did an SVC upgrade including node swap to new hardware this weekend. Went from ----wait for it----- 4.3(!!!!!!) to 7.2. Overall it went very smoothly but I'd be lying if I didn't feel a little anxiety at times.

In other news, I just configured my first Flash 820 and presented to the SVC. Next I get to set up a Vdisk mirror and see how this sumbitch performs with Oracle.

I'm seriously considering consolidating our entire VMware environment (about 45TB) to a Pure FA-420. I can get 60TB usable (assuming 5:1 compression) for about 240k. Anyone have any first hand experience? It seems like a solid product and perfect for VMware.

NippleFloss posted:Why would you assume 5:1 compression? You're going to trust their marketing that your data will fit because compression is magic? At least make them demo it and prove it. Because if we don't get 5:1 they will give us more flash to make up the difference. It seems well suited to VMware due to the RTC, dedupe, and free replication. I'm not sold on it but I do like the upfront licensing model. I could get 3 shelves of 900GB V7K plus SVC licensing for around 200k or spend another 40K and get a sexy new flash array.

adorai posted:Trip report: We were going to purchase a new netapp 8020 with a few shelves and complete pack for roughly $150k, including five years of maintenance. Instead I purchased a pair of Nimble CS300 series arrays for slightly more, and the performance is astounding. Not being a unified device is a big draw back, but I have some zfs appliances that can step in for cifs. Seriously, if you are buying storage right now, Nimble is pretty drat awesome. Out of curiosity, do you have a FC infrastructure? bull3964 posted:We're demoing a Pure FA-420 right now. We just got our 10g networking up and running last week so we don't have a ton of stuff on it yet, but there's some mix of VMWare and just LUNs carved out to individual machines for various things. We're going to be speaking with some existing midsize health systems tomorrow about their Pure implementations. My problem is my storage needs are becoming increasingly difficult to manage. I have an aging DS8100 that now needs more space, volume mirrors from the DS to a flash820 that needs more space, a DS4800 I need to replace soon, a v7000 that's close to maxed out and not under SVC currently. I have a 30 host VMware environment with data stores from both the standalone v7000 and an SVC with v7000 backend connected to a totally different fabric. It's getting really loving hard to manage. Not to mention three separate n-series, two unified v7000's, DS4500, another DS4800 and SVC/v7000 at our DR site. All of this connected to a fabric of out of support 2005-b5k switches that aren't meshed properly so I have ISL issues constantly, etc etc etc Ok, I'm done bitching poo poo, I forgot about the 2 new v5000's ready to be configured for a new Tivoli implementation.

We will begin looking to replace our DS8100 soon-ish. We (probably) won't be going with IBM. What's infuriating is the worthless Client Executive in this area is still there. These guys make like $120k on average and in this area that's a lot of loving money. I know for a fact the CE guys get paid dick for the crazy hours they have to pull. The Client Executive provides the customer with no value and is mainly just a thorn in our side. Seriously, this guys main existence, as far as I can see, is sitting in the middle and taking a piece of the customer pie. Kaddish fucked around with this message at 21:32 on Jan 30, 2015 |

We're going through a switch upgrade. We currently have old IBM 2005-B5K's (rebranded Brocade) and we're going upgrade to Directors. Our hardware rep has scheduled a call with Brocade and Hitachi - evidently Hitachi also sells rebranded Brocades and we can save some money. Any use Hitachi Directors? How is support?

Zephirus posted:They're not even re-branded afaik. They're just brocades - at least that is the case for everything brocade i've bought through HDS. Support is OK, but with HDS YMMV depending on your area. APAC is not great, UK/EMEA is ok, US/CAN i've had good/bad experiences but not enough to judge. Awesome, I didn't realize they weren't even re-branded. I popped over to the brocade website and that does seem to be the case. So support will be my primary concern still. Thanks for the info.

So, I've had about a week to play with a Pure FA-420. I'm using it for VMware. It took me a bit to wrap my head around the relationship between thin provisioning to the hosts and the de-dupe/compression on the backend. Let me just say this thing is pure magic awesome. VMware think it has 24TB in 6 datastores. Of that 24TB it says its actively using about 10TB. On the backend it's actually using 3TB on disk. Two thumbs up from me!

Anyone have a chance to play with an IBM Flash 900 yet? I'm replacing a DS8100 later this year and have been weighing some options. With pretty much any system these days reliability is pretty great. I'm not seeing the point in something like DS8870 considering the cost. Right now I have our main EMR Oracle DB mirrored between a Flash 820 and DS8100 via SVC.

If you're using block level de-dupe and compression at the storage level, it doesn't matter if your vmdk is thin provisioned or thick. A block is a block and it's either being used on the array or it isn't. At least this is true on Pure, which is the only de-dupe/ compression/thin provisioning I use. As mentioned above, make sure you utilize SCSI UNMAP periodically, especially if you have aggressive DRS. This doesn't run automatically. You will need to run it against a datastore from any host in the cluster. Kaddish fucked around with this message at 15:46 on Aug 17, 2015 |

If you really want to see actual storage usage from one interface Nimble probably has a plugin for Vcenter. Pure does.

I worked on a quote last year for a complete pie in the sky scenario to replace all of our IBM v7000's with new storage last year. I went with IBM again because I love SVC. (not that I needed to, I guess, but I do like Storwize) My FlashSystem 5100 for prod and 5030 for DR were delivered, out of the blue, a couple of weeks ago. I'm going all DRAID bitches!

lol internet. posted:Hmm, I seem too of started to lose a LUN on a cluster that's been up for like a year. Did you resolve this? It sounds like a fabric/hardware layer issue. If this is FC, and I assume it is, you might want to look at C3 discards on your target/initiator ports. A slow drain device could cause this, which is also the bane of my existence.

Pikehead posted:More News: Um. Why do you have 40+ Pure LUNS is the pertinent question? I can't fathom a reason for this. Like, you're trying to fix something that seems to be fundamentally broken, and fixing the fundamentals will help with whatever you're trying to do going forward. Edit - I see, it's the LUN naming convention that is the problem, which gives me a headache even thinking about. Pure LUNS are just a storage bucket, and unless you need specific compression/dedupe statistics per Pure LUN, they don't mean anything. And even if you need those stats, just create a 'test' LUN for compression/dedupe potential. Or, there's always vvols (lol) Kaddish fucked around with this message at 01:59 on Mar 4, 2021 |

Edit - The new Storwize code has the option of setting up a storage array, including pools, mdisks, etc for SVC best practices, I tempted to try it. I'll need to recable/rezone my DR SVC cluster first to get NPIV working, though. Kaddish fucked around with this message at 14:39 on Mar 4, 2021 |

ihafarm posted:After 10+ years running a couple generations of EMC storage(Celerra/VNXg1) I opted to go with Nimble for my most recent refresh. Still migrating over, but have been converting some non-user facing systems to vvol, what gotchas should I be worried about? I already knew that veeam doesn’t support direct backup from vvol data stores(at least w Nimble), but that’s not a concern in my environment. Seems like any enterprise I actually haven't used vvols yet because it seemed to me the limitations and implementation was ....severely lacking. Vvol support wasn't even added to Storwize until later in the 7.x code stream and converting over seemed like a pain. Maybe the APIs/implementation/etc has gotten better over the years but it seemed like they attempted to solve a problem I didn't need solving.

This is definitely true with regards to investing time reaching a resolution but at the end of the day, in the corporate world, placing the responsibility on the vendor to provide a positive outcome is key to long-term job stability. I've identified several issues over the years, the biggest one off the top of my head was a serious SVC metromirror issue that led to data corruption. IBM released a version revision and I had a feather in my cap in the eyes of management.
