So... This arrived on Friday


Anyone interested in any test?
I have a test rig setup and can run different tests. Just let me know which ones and with what parameters.

lp, Matej

They will be used in a project as a ZIL. I will build my pools next week, I hope for some good performance[emoji3]

Did you pay less than my sale thread? Wondering why those haven't seen any nibbles!!!

What configuration are you going for BTW?

I am planning to use 2 for my setup. Probably backed by 10kRPM drives, I'm not sure if I'm going to split them up or run two for one pool, etc..

I can't say how much I paid, but they weren't cheap:) On the other hand, I'm from EU, so prices here are way higher that in US?

As for configuration, I'm not sure, we have a few up out sleeves(1 pool with RAID10 ZIL, 2 pools with RAID1 ZIL,...). I have to do some testing this week.

I did some tests with FIO tool and here is a little spreadsheet with the results:



All this was running on the following hardware:
* Server: IBM xServer 3550 M4
2x Xeon E5-2640
265GB Memory
LSI 9207-8e HBA card with P19 firmware

* JBOD: Supermicro SC837E26-RJBOD1 with SAS2 backplane (connected with single or dual path)

* OS: OmniOS v11 r151014
For ZeusRAM multipath to function, you need to edit /kernel/drv/scsi_vhci.conf and add:
scsi-vhci-failover-override =
"3PARdataVV", "f_sym",
"COMPELNTCompellent Vol", "f_sym",
"OCZ TALOS", "f_sym",
"STEC ZeusRAM", "f_sym",
"TOSHIBA MK1001TRKB", "f_sym";

Care to share the setup you're using to test?
Backplane? Chassis? CPU(s)? RAM DISK? ZuesRAM <-> ZuesRAM ? OS/Version? Etc.. :)

OMG, I was writing as a total noob:)

I updated my post with all the necessary data. If I forgot something, please let me know.

I will talk to my boss if I can start a new thread about the HA setup I'm building.
