The Question is:
I feel like someone should ask this every so often...
The DS10 and DS20 AlphaServers provide very good value for "scale out" and/or
I/O intensive computing, and even in light of the migration away from Alpha to
IA64, Digital, Compaq, and the proposed merged company have a good track
record for supporting har
dware after it's final sale date. Given these servers currently outperform the
first-draft Itanium servers, they're well worth their price.
However, while Tru64 has an Ultra-2 RAID controller for these systems, OpenVMS
does not. This is especially embarassing since similarly priced Proliant
servers have an Ultra160 4-channel RAID controller supported under Linux and
Windows. The DS-series o
f AlphaServers are somewhat behind the times, storage-wise.
External RAID controllers are priced very high compared with the cost of these
systems. Fiberchannel even more so.
Can the Wizard provide guidance on attaching redundant storage to these
systems? Can his (her ?) crystal ball provide any guidance on future hardware
support for these models?
The Answer is :
Because OpenVMS handles multi-path operations and supports fully shared
disk access, the use of off-bus RAID controllers (eg: HSG, HSZ, etc) and
host-based RAID (host-based volume shadowing) are the most common and
most expected approaches.
