DDS Technology Attributes
• No further development planned• Highest volume tape technology in service today
(12M drives)• Relatively low drive cost, very low media cost• Best used in:-
— low end servers—high capacity interchange— OS recovery device (using OBDR)
• 4 generations with backwards compatibility• Only rated at 12% duty cycle (3 hours per day)• Cost effective entry level automation• Successful because of standards HP, Sony Seagate

Ultrium Technology Attributes
• The new tape technology for the Enterprise from, HP, IBM & Seagate.• 4 generation roadmap until 2007 (800GB/160MB/sec native)• “Best of Breed” technology approach, GEN1 technically conservative.• 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

SDLT Technology Attributes
• Quantums new Enterprise technology• Revolutionary new servo system LGMR• Lower Performance (11MB/sec) than Ultrium• Has 2 sets of heads to be able to read older DLT tapes• Compromise leader design to load older DLT tapes• No DRM but large (32M) buffer• Uses PRML to get high capacity• Infra red diagnostics port• Single source• Future roadmap keeps changing

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).

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 .

You don’t need to do a full backup every night – use incremental or differential backups to reduce the time on
after a full backup.
