Hi! I bought x4270 servers for (write heavy) mail server. And waiting for delivery. That have two Intel SSD X25-E(for ZIL) and HDDs. x4270 servers have hardware RAID card based on Adaptec's RAID 5805 adapter, which has 256MB BBWC.
SSD has write cache and RAID card also has BBWC. When set write-back on BBWC and enable SSD's write cache on RAID card, ZFS can flash the BBWC and SSD's write cache too? When the answer is no, should I set disable SSD's write cache? I think disabled write cache reduce the usable lifetime of SSD. Because wear-leveling on SSD is not applied. And one more question. Which RAID function should I use hardware and ZFS? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
