[OpenIndiana-discuss] [informational] HyperX Predator PCIe SSD usable as ZFS cache device

[the outsider]

Just to inform everyone, i tested the HyperX Predator PCIe SSD 240GB in a HP
ML350G6 server yesterday and it was detected by the OS as a new drive. 

I must say I that the OS was SmartOS, but I am almost certain that the
device will work on OI also. 

 

I have attached it as a cache device  to my ZFS mirror and it worked very
well. 

Unfortunality HP made a crapy bios for the ML350G6 which detects the PCIe
device and adjusts the ventilatorspeeds to 70% without any need. 

Since I use the ML as a home/office server the increased acoustics of the
vents made me crazy and I removed the Predator. 

 

When I have time I will install it in a server in the datacentre where we
have a 16x 300GB ZFS storage and I can run different benchmarks.  

Format detected the device without any troubles as c1t0d0 and I could
partition it. 

It would be nice to create some partitions for cache and ZIL on the device,
but I don't know if ZFS needs a whole drive or just a partition?
