The NetWorker 7.1.3 server I manage is a Sunfire V480 with Solaris 9.
Connected to this server is a Store Edge A1000 disk array which is devoted
to our entire /nsr disk volume and each physical disk in the array cabinet
is mirrored. This provides a reasonable level of data protection and it
works well. Not long after we put our new server into production, one of
the disks on that A1000 failed and so did a controller. We didn't lose a
single byte of data, nor did we lose any production time. The hardware was
fixed during idle hours and the data on the failed disk drive was not lost
because it was available on its alternate drive.
