Always, always perform benchmark analysis of any new hardware,
software, or network units before committing their use to an
application such as TSM. This is an essential element in the
acceptance phase of new acquisitions, to assure that they meet
advertised performance levels. If the new stuff
My money is on the SATA disk pool. I ran into something similar with many
spindles of SATA disk and was expecting it to fly. nope.
We found out that not only was the disk I/O not as expected but that device
the disks were in only had 2 I/O ports that were supposed to be in failover
mode. But we

Indeed. Vendors often cite SATA and SAS technology throughput rates,
leading the customer to believe that
Good day everyone,
I'm looking for some workable suggestions for larger lun backups.
I'm talking 1.5tb and larger lun sizes. I have a number of remote sites that
have large quantities of hi-res image files and they need an offsite backup
solution. Usually we are notified before the disks go into

Sumthin' wrong with those numbers.
If you have a GigE pipe, you should be able to send 70-80 MB/sec. thats
400+ MB/min, 240+ GB per hour, 4+ TB in 24 hours.
So, either
- your clients are having performance issues with their own disks
- maybe you have compression or something else slowing down
