Can anybody tell me how to measure the raw performance of a new system I'm putting together? I'd like to know what it's capable of in terms of IOPS and raw throughput to the disks.
I've seen Richard's raidoptimiser program, but I've only seen results for random read iops performance, and I'm particularly interested in write performance. That's because the live server will be fitted with 512MB of nvram for the ZIL, and I'd like to see what effect that actually has. The disk system will be serving NFS to VMware to act as the datastore for a number of virtual machines. I plan to benchmark the individual machines to see what kind of load they put on the server, but I need the raw figures from the disk to get an idea of how many machines I can serve before I need to start thinking bigger. I'd also like to know if there's any easy way to see the current performance of the system once it's in use? I know VMware has performance monitoring built into the console, but I'd prefer to take figures directly off the storage server if possible. thanks, Ross This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
