HP is the ONLY vendor to have a half-height Ultrium product (Ultrium 215). HP Unique “data rate matching” to ensure streaming on lower performance hosts. Designed for automation – ultra-reliable load/unload, Cartridge Memory (future), surrogate scsi High data integrity – data can be recovered even if 32mm of tape is completely unreadbale. OBDR support LOW RISK

Introduction to tape technologies HP Restricted May 23rd, 2001 Page 16 Where to connect the tape drive/Library Direct Attach (DA) – Tape is attached directly to the server it is backing up. Used generally in small/medium businesses where there is no centralised backup policy. This market is still a very high revenue earner for HP – everytime you sell a server – sell a backup solution. Over the Network (OTN) – Tape drive or more likely an autoloader/library is connected to a “dedicated backup server” which backs up remote servers over a dedicated backup LAN. Allows centralised backup and easier manageabilty.Network bandwidth on 100 baseT can be an issue, ( MAX 25GB Hr) but Gigabit Etherenet (1000BaseT) is allowing higher performance tape drives to be used in this environment (MAX 234 GB/Hr).

Introduction to tape technologies HP Restricted May 23rd, 2001 Page 17 Where to connect the tape drive/Library Storage Area Networks (SAN). – In this implementation Libraries are shared by multiple servers via Fibre channel allowing maximum backup/restore flexibility. The data can always be made accessible even if a particular server is down. However the cost of a shared FC Library in a SAN environment can be high. SANs are not yet fully plug and play – check with your storage specialist to see what confgurations are supported by HP. Extra Server Sales! – remember that as well as selling Application based servers, somewhere in the corporations infrastructure will be a requirement for dedicated backup servers with Tape drives/Libraries attached and potential sales for HP OmniBack software.
