I guess as long as I don't provide proprietary info, I can touch on the storage we're using. It's not like it's top secret, but I like to protect my IRL identity as much as possible. If someone works with me and sees this, they'll know who I am though
NetApp 8040: Not technically AFF, but our first all-flash array. Used for SMB/NFS. All VMware stuff was NFS. We still have some stuff on this but we've mostly moved it to new arrays as we've had the 8040 for about seven years now or longer. I'd have to look back at when I bought it.
EMC VNX (several models): Used these for block storage, primarily for dev/test Oracle servers. These were retired just recently.
EMC XtremIO (1 and 2): We've been using these for a while as our primary block storage for Oracle and now all production workloads. Easily my favorite array for block storage, probably because it wasn't technically made by EMC. Tons of RAM/Compute and four active controllers in a dual-brick setup. Unfortunately, EMC is no longer doing anything with this and letting it die.
EMC Unity: We have a few of these. Least favorite EMC array. Poor performance all-around and full of bugs. EMC has quickly made PowerStore which is clearly based off Unity but not nearly as bad a product. Sucks for file workloads, block is OK. This is supposed to be the next iteration of VNX but instead of improving on VNX, they removed functionality and somehow improved nothing on file workloads.
EMC PowerStore: The primary tray of storage (with the controllers) is NVMe where as any expansion storage isn't. This is what the Unity should have been. Still sucks for file workloads, OK for block. Not sure if we want to buy more of these as they seemed to also learn nothing from the Unity failures and are doubling down on "simplifying" the storage to the point where it's a pain in the ass to use outside of extremely basic use cases.
I'm looking at Pure Storage next. Always been a fan of what they're doing and wanted to use them sooner, but we had some challenges (we were sold two times in the past few years) that screwed up all our plans. We'll probably go back to NetApp in the future for our file workloads. Nobody can touch them on that.
