2004/5 -------------------------------------------------------------------------------- HP (only one that has ) LTO has adaptive tape speeds HP recommends either SDLT or LTO, LTO for new customers main competitor - Stek ESL high end (librarires) ESL 9322 ESL 9595 - 16 drive, 595 slots, cacasdes to 64 drives, 2278 slots (4 units) host pluggable (hot swappable and new additions online) power and cooling - 2n (8ps, loose 4 before you degrade) enterprise backup solution: HP SAN qualified components: TAN&SAN compat bridge on library to do FC - up to 2 drives per FC port LTO run at max 65MB compressed -------------------------------------------------------------------------------- STK grew from larger to smaller LTO and 9x40 LTO2 is midrange in their view most companies moving away from DLT stk is open to new/better tape tech into libraries LTO2 - high competition for media, lowest cost every 9 months get upgrade in tech can mix media type within frame, also partition 9840 - fast access (11s) for archive/HSM, lower capacity worm 9940B - slower access, higher capacity, 1 failure in 100K loads 30mb sec, 200 native Imation is manufactor lower than LTO2 per gigabyte - 300 tapes is crossover between worm: Volsafe - can append, but not overwrite 2GB fiber: mcdata or brocade one to one for port and tape drive 9310 3.6PB (1.2PB w/o compression) COD L5500 - LT0 and 9940 & 9310 and only 9940 up to 132000 slots, 960 drives 5500 slots 80 drives 4s to mount tape need to use ACSLS no PM L700e 1340 slots and 40 drives (2 frames) mixed drive type can have internal computers inside web monitoring hot swappable fibre channel 20 drives (LTO), 12 9x40, 384 slots, 678 slots no PM bladestore B150 DR, DW, backup 5 RAID0 ATA disks attached via fibre 12.5 TB in rack supports other RAID levels 250TB in 3 racks parallel ATA versus serial 64 host partitions 95K for 6TB 304 for 36TB -------------------------------------------------------------------------------- spectralogic Gator 64K AIT strong 60M financial, 250 emp AIT-3 now, AIT-4 spring 04 32 dr 645 slots COD for slots (start at 100) scsi, fibre, GbE 16 logical partitions HSM w/ AIT can be OK (the cataloging of data) maint: normal next day for h/w can get 4 hour response (Gruman, Kodak, ???) can get self-maint spare parts kit can get tools kit -------------------------------------------------------------------------------- HP use bridge instead of FC ports scale 4 scaled units, pass thru, 4*qty SDLT & LTO most components are hot swappable suggest using many of these units in a DC redeployment flexible LTO HP drives have (variable) adaptive tape speed for transfer IBM drives have only 3 speeds use 2-3bay HPs at HQ one mail slot between cabinets who manages mailslot queue, can buffer up in queue, does HP or BU s/w manage this queuing? may have 5 cabinets in the future (can do now, but being qualified) SNMP monitoring s/w: tapetools optical 50GB with new tape strategy is strong LTO investment quantum w/ SDLT SATA investment hostpluggable/hotswappable, number of drives per controller 15 drives 5 shelves (90 drives) HSM - second Tier (disk first) data protector - product WHY HP??? HP does large qualification with their storage, OSs, and ISV LTO technology - right and newest drivers modular - flexible, upgrades, investment protection, redeployment, redundancy enterprise backup solution - integrated controllers (bridge) less ports and deals w/ conflicts integration w/ XP (EDM like) proven and works partitions - yes multiple tape (lto and dlt) -------------------------------------------------------------------------------- ATL/Quantum P7000: LTO2 80 d, 2394 s, 479.0 TB ADIC 10K: LTO2 324 d, 9582 s, 1916.4 TB STK L5500: LTO2 80 d, 5500 s, 1100.0 TB Spectra Python: LTO2 120 d, 6250 s, 1250.0 TB HP ESL9000: LTO2 64 d, 2278 s, 455.6 TB --------------------------------------------------------------------------------
