Dear Friends,
I am using Veritas DMP with Solaris 2.6 (VxVM 3.2). The storage is XP512, an
oem of Hitach Lightning 9660 in direct attach mode.
So far, I used Jaycor FCE-1063 adapters (1GB/sec). However, I plan to add
more HBA's and I'm thinking at FCE-1473, 2 GB/sec, also to be used direct
attached.
Most likely the final setul will have 4 HBA's of 1GB/sec and 2HBA's of
2GB/sec
The questions are the following:
1. How will VxVM 3.2 handle DMP over controllers of different bandwidth ?
Will send disk blocks over each interface in a round robin fashion,
therefore wasting extra bandwidth of FCE-1473, or will adapt itself to use
more bandwidth of FCE-1473 ?
2. Did anyone used such setup without problems, are data corruption risks
associated with it ?
3. The FCE-1473 interface salesman (which is from HP) insist only Solaris 7
and 8 are supported, in which case my setup won't work because I'm stuck for
the moment with Solaris 2.6, but on FCE-1473 datasheet from Jaycor website,
Solaris 2.6 is supported along with Solaris 8 and Solaris 7. What is your
experience with this card ?
