When is SSD a MUST HAVE for server? thoughts? Discussion :D
-
@Lyndsie_xByte Thank you! That was very quick! I didn't even know you could cachecade on the front.

@Lyndsie_xByte said:
Thanks for the mention @scottalanmiller , @wrx7m - Just talked to the engineers. Short answer is yes. If you put the SSDs into the rear backplane, the system will automatically ask if you want them to be cachecade disks when you configure them. If you add then into other slots, you can change them into a cahcecade array when you are editing the controller settings. You press F2 to select the type on the settings.
I should be able to do a hot add, right? Then configure from iDRAC? I would like to do it without taking down the server, if possible.
-
Yes, should be able to. iDrac should work or a software utility.

We use Edge SSD that we got form Xbytes and very ahppy with it. Sure SSD cost more but man they are fast. And like Scott said you can do RAID 5 with SSD so you get more storage than RAID 10 but still blow the doors of any spinning drives.

I wish something like this existed for HP.

Same here. Blazing.
Which reminds me I should get back to that thread I created about the blazing drives.

I'm still looking around the site, but mainly I am looking for an Edge SSD type solution for HP (i.e. a fully supports non HP branded SSD drive that I can do blind hot swapping with.)
-
HP doesn't have any blind swapping limitations on third party drives. At least not as far as I've ever seen.

Ah, all I know about HP servers at the moment is that ServerMonkey offers used models like xByte does. Sounds like HP is just harder to find 2nd hand equipment that works properly, uck.

What was/is the issue with using off the shelf SSDs in HP servers then? Other than MLC/TLC have shorter lifespans than SLC (and I'm not sure that Enterprise class drives are even SLC)?

They don't have the trays or firmware to talk to the OS.

I thought a source was found for trays (maybe not). The firmware is the issue - (is it really the OS or the RAID card?). This comes back to the ability to blind hotswap drives - can you blind hotswap non OEM drives in a HP without potential for data loss?

Firmware has never been a factor in blind swapping. Can't, or else blind swapping would not be able to work.

I guess the question is, how do you know when you have a failure if the firmware on the SSD can't properly report it to the RAID controller?
-
Let me ask this another way.
Scott - would you be willing to run non OEM SSD in a HP server with an HP Server RAID card in a production environment? And if yes, what drives?
If no, why not?

Ah, now reporting, that's the issue. Failures are often not reported correctly. But the blind swapping works just fine.

No, because ...
-
I pay for that gear for the purpose of getting support. Bypassing that rarely makes sense. You should question your use of HP hardware if you are going to have these thoughts.
-
Non-OEM SSDs will not report to the RAID card to report to the hypervisor or the ILO to tell us when something is failing.
IF you want HP gear but don't car about support AND you are happy with software RAID, then this would be fine. But why not run SuperMicro then?
-
-
My emotions make me say - I want HP level support on the hardware (mobo/raid/ram, etc) but want pricing on the drives to be more inline consumer stuff.
I'd have to do a price break down, but it seems that the mobo/ram are moderately priced higher than prosumer stuff, yet we get the awesome support HP provides - but in drives, we get utterly bent over. The drives are 2-300% more expensive.
-
I understand that we want to care about our data - but it's hard overlooking the sever price increase for Enterprise OEM drives.
