Hi,
We are looking to implement a large scale SPARC Solaris system which has two
main priorities.
1. Disk latency - ie fastest possible return of any calls to disk IO
2. Failover to remove site
I am investigating using a Veritas to manage a SAN mirror of Fibre Channel
disk arrays. The application writes relatively little data.
Does anyone know how attaching a FC mirror several kilometres away will
affect the disk i/o latency?
How does the i/o latency of an internal disk compare to that of a tuned FC
disk array?
I will summarise, thanks in advance,
Conor
