Tech Field Day 8 Presenter Lineup

September 13, 2011 By Stephen 1 Comment

The Bridge: Veritas Thin (Provisioning) API

January 6, 2011 By Stephen 1 Comment

Thin provisioning needs communication to function, and zero page reclaim is only the array side of the story. WRITE_SAME helps reduce I/O load, but the server needs to use it. Wouldn't it be nice if the operating system, file system, or volume manager would use these commands to help recover capacity? We need a bridge. We need to cross the gulf between the storage array … [Read more...] about The Bridge: Veritas Thin (Provisioning) API

Multipath: Active/Passive, Dual Active, and Active/Active

Symantec’s Thin API Is A Step In The Right Direction

October 16, 2008 By Stephen 21 Comments

Symantec announced that their widely-used Veritas Storage Foundation software (more commonly known as Veritas Volume Manager and filesystem) will now include thin provisioning, migration, and a new API which allows it to directly communicate with thin-capable storage arrays. This is a smart step, certainly, and ought to be useful, but storage managers should still try to manage … [Read more...] about Symantec’s Thin API Is A Step In The Right Direction
