Hello experts, I was hoping some of you have 1 or more of the following items in house and can answer a couple questions for me. I am looking for folks that actually use these SANS on a daily basis, and not someone that has done their own research and assumes they know the answers.(not to be rude at all, as I have done extensive research and still do not have a clear answer/understanding).
For Nimble Storage, Do any of you have the CS300 in house and if so, how much usable disk space do you have available as soon as you plug it in versus what you thought you were getting when you signed the PO(or initiated a POC).
We are looking at a Nimble CS300 with what they claim is roughly 23TB "base raw disk capacity". I know they are saying 23TB raw, but that number appears to be done before the overhead, hotspare, etc... So I am wondering exactly how much disk space I would see if I took this unit, made 1 giant LUN, how much capacity would I see before any compression is done at all.
The same question applies for the Pure Storage FA-405 and FA-420. I am nervous as to the wording when we look at these specs, The 405 claims it gives "up to 40TB", but the spec sheet states "2.75 - 11TB raw capacity".
The FA-420 states it gives "up to 125TB" but the spec sheet states "11 - 35TB raw capacity". I can not seem to get a straight answer.
I want to see 20 or more TB available when I fire up the unit. I do not want to rely on compression/deduplication to achieve my desired capacity and I want that capacity to be 20TB or more AFTER all the overhead/hotspares/etc...are factored in.
Do any of you have any real life experience with either of these units and can you tell me what your actual usable capacity is/was when you first plugged it in, and also how they are performing.
In the case of Nimble, As they do not do dedupe, I am curious as to how well it does in compression in a fairly sized exchange environment.(3-4TB).
