BE 12.5 Backups are slow upon new SAN implementation
Posted on 2010-08-29
I need some advice about BE12.5 and slow data transfer and LTO4 drives going offline
We had backups running on two tape drives (one HP Storageworks 960 LTO3 via SCSI Cable) and one Storageworks 1840 LTO4 drive (SAS connection) Both Storageworks drives are directly connected to a DL380 G4 server running Windows 2008 server.
Data - We have an Iomega® StorCenter™ ix12-300r which is connected by ISCSI to our FP server. Currently, we have only one ethernet connection (cat6) to SAN, which in turn is connected to the SAS vis ISCSI.
The LTO3 SCSI - drive is backing up our Exchange server (ok and is working, but is slow 250-350 Mbs)
The LTO4 SAS drive - is backing up from our FP server /The FP Data is located in the SAN
the LTO 4 (SAS) drive drop connection intermittently in BE12.5 (12.5 Rev 2213), which cases us to restart services, if the drive spans, we loose the second tape data because the drive goes offline.
Problem2 - We are seeing speeds between 250-250MBS which cause our backups to run near 24 hours.
How can we speed up the process and address the drive offiine problem?
