SANs in the Enterprise?
-
Why do they have a FreeNAS server instead of a more normal NAS, like a Synology or ReadyNAS?
What you need for storage normally has less to do with the number of users you have, and more to do with the workload that storage will be under.
If you're looking for some suggestions, you might consider laying out the entire current environment (how many physical servers, how many VM servers, how many VMs, what those are all running, what applications are running in your environment, etc)
Using that information we can start to make recommendations for you.

A SAN that I'd actually put in place would be along the lines of VNX/VNXe, 3PAR, or EMC VMAX. No, I've never actually deployed any of them. The biggest project along that sort of line I was involved with was back in the late 90s, and that was a NetApp, which was more than a bit of a flubbed project all around.

We use and are relatively happy with Nimble here.
-
The big thing that the OP should be considering is - do I need a SAN? Is my current SAN and IPOD (inverted pyramid of doom)? How much more expensive is my IT setup because I have a SAN and do I really gain anything from it?

We're in the process of deploying a Dell MD3820i SAN with self-encrypting drives. It will give us 18 TB usable once fully configured if memory serves and has 4 SSDs for caching. This is for a PEO headquartered in Dallas. We have around 60 employees and will end up having about 15 or so VMs in our cluster of two ESXi hosts (maybe slightly more VMs). This is only site # 1. I believe we will have this setup mirrored in our datacenter later this year and will eventually begin to host different things for clients.
The SAN and other gear had been purchased already when I started here in early December.

A MD even, at least it's not the MD2000 series, not that that is saying much.

I'm doing research for comparisons to an environment that I'm working in now with FreeNAS as the primary san in the enterprise.
Ewe, yuck.
Yes, I'm trying to convince them to move away from that "investment" and it's so heavily ingrained, that I'm having trouble pulling the kool-aid out of their fridge even as it's killing them.

Yes, there's an MD2000 here with 2x FreeNAS augmenting them. 500 users. 126 VMs. See above about the kool-aid.

Wow, I think you might need some heavyweight backup with this @grey!

A pair of Dell EqualLogics. 4 TB 15k SAS on one and 8 TB 7.2K SATA on the other. I call it manual disk tiering
Housing Hyper-V CSV's for about 100 VM's. Most of the data is in Windows file servers for roughly 500 users.Luckily these are aging out soon - as will this architecture.

Are you gonna dance a jig on the corpses when they go away?

@travisdh1 you can count on that!

OK, well, that's a sizable number of VMs, you might have a good reason to have a SAN. How many VM hosts do you have? How much VM storage do you have/need?

My buddy takes the IT team to the farm, and they literally blast the old equipment to dust! Great way to bring a team together after a heavy project

My (3) Dell Equallogics are now one big backup target. I'm running a HP MSA with tiered storage now. When I put it in we were running VMware Horizon (View). That environment is gone and so is my need for crazy IOPS.
Next time around, it should be easy to convert to direct attached or a Scale system.

The corporate team has a few LeftHands but they are switching to NetApp. For our stuff, VMs are local and we use Isilon for our storage.
-
@Dashrender said in SANs in the Enterprise?:
Zero - all data is local inside my VM servers.
Ditto + several NAS
-
ZFS NAS appliance + 3 hosts in front. Next version will be mirrored local storage.

I would recommend looking at what StarWind Virtual SAN can do for you. This is a Windows native software that can be installed directly to the host and does not need to be an appliance, but still can be inside a VM if needed. Also with our software you can build a 2 node HyperConverged cluster (Windows/VMware/Xen) with highly available storage pull that supports SMB-direct and iSER. You can also take a look at HP VSA.

We use PURE storage for 90% of our VMs and Dell Compellent for cheap and deep and the rest. I believe we are on the SC9000, but I would actually have to look. Needless to say, it's got lots of storage, and we got lots of them.
Currently sitting on ~6000VMs throughout all our datacenters. Not counting the 200+ we have internal to us.
