Hi I've bee doing several test on quadstor vtl, and had nice perf (close to 100MB/s sometimes) decided to switch to disk backup using quadstor storage, and perf are very low on same hardware (only a couple of MB/s)
using HP servers DL380 g6 / smart array p410 DL380 g8 / smart P420 or P822 sata drives (12x 4TB 5900rpm or 22x 1TB 7200rpm) raid 5 or 6 all accesses or done through 4Gb/s FC once switches to quadstor storage, i can see on the quadstor system in iostat that disk at 100% almost all the time, with between 500KB and sometime up to 7-8MB transfer (but more rare) could it be something related with block size the storage is writing, compared to VTL to make the RAID controler saturating or something likt that? -- You received this message because you are subscribed to the Google Groups "QUADStor Storage Virtualization" group.
