I'm in the process of repurposing some hardware and building two identical machines for ZFS based storage and need some advice regarding SLOG/L2ARC disc choice and layout. Intended use is NFS based vSphere storage for medium load VM's.
vpshere Cluster consists of 15 dual cpu hosts connected via dual port intel x520-DA2 card to arista switches.
1st the hardware allready available :
As I have no experience with multiple drives for both SLOG and L2ARC, I'm looking for advice. For SLOG drives I was thinking about 2 to 4 Intel S3710 200GB drives, and for L2ARC I have a lot of 240 GB Samsung SM863 drives available.
What about layout? Can anyone advise? I have 14 drive slots spread over both controllers equally available to support SLOG and L2ARC drives. Before I go out and buy the wrong SSD's or the wrong amount for the wrong layout I could use some help.
