Hi all, The more readings i do about ZFS, and experiments the more i like this stack of technologies. Since we all like to see real figures in real environments , i might as well share some of my numbers .. The replication has been achieved with the zfs send / zfs receive but piped with mbuffer (http://www.maier-komor.de/mbuffer.html), during business hours , so it's a live environment and *not *a controlled test environment.
storageA opensolaris snv_133 2 quad-core amd 28 gb ram Seagate Barracuda SATA drives 1.5TB 7.200 rpm (ST31500341AS) - *non-enterprise class disks* 1 RAIDZ2 pool with 6 vdevs with 3 disks each connected to a lsi non-raid controller storageB opensolaris snv_134 2 Intel Xeon 2.0ghz 8 gb ram Seagate Barracuda SATA drives 1TB 7.200 rpm (ST31000640SS) - *enterprise class disks* 1 RAIDZ2 pool with 4 vdevs with 5 disks each connected to a Adaptec RAID controller(52445, 512 mb cache) with read and write cache enabled. The adaptec hba has 20 volumes , where one volume = one drive..something similar to a jbod Both systems are connected to a gigabit switch without vlans (switch is a 3com), and jumbo-frames are disabled. And now the results : Dataset : around 26.5 gb in files bigger than 256 KB and smaller than 1MB summary: 26.6 GByte in 6 min 20.6 sec - average of *71.7 MB/s* Dataset : around 160gb of data with files small (less than 20 kb) and large (bigger than 10MB) summary: 164 GByte in 34 min 41.9 sec - average of *80.6 MB/s* I don't know what about you...but for me it does seems very , very , very good performance :), specially if i consider that in overall these two systems cost less than 12.000EUR . Does anyone else has numbers to share? Bruno
