The SNDR portion of AVS does block-level sync and async replication. It is a dead project because such architectures worked well when disks were 9GB, but suck most heinously when disks are 4TB. I'll lump DRBD and HAST into that group too. What you will find is that they are easy to setup, easy to fail over to the remote site, and impractical to return to the original site. As Robert says, the only way to handle multi-site redundancy is to implement above (application) or below (ZFS). At Coraid, we have the technology to do the below: wide-area mirroring. Joyent's customers, and many cloud apps, tend to implement above. Being stuck in the middle is a bad place to be. -- richard ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
