The Cost of Storage about 1K$/TB 12/1/1999 9/1/2000 9/1/2001 4/1/2002

Disk Evolution Capacity:100x in 10 years 1 TB 3.5” drive in TB? in 2012?! System on a chip High-speed SAN Disk replacing tape Disk is super computer ! Kilo Mega Giga Tera Peta Exa Zetta Yotta

Disks are becoming computers Smart drives Camera with micro-drive Replay / Tivo / Ultimate TV Phone with micro-drive MP3 players Tablet Xbox Many more… Disk Ctlr + 1Ghz cpu+ 1GB RAM Comm: Infiniband, Ethernet, radio… Applications Web, DBMS, Files OS

Intermediate Step: Shared Logic Brick with 8-12 disk drives 200 mips/arm (or more) 2xGbpsEthernet General purpose OS 10k$/TB to 100k$/TB Shared –Sheet metal –Power –Support/Config –Security –Network ports These bricks could run applications (e.g. SQL or Mail or..) Snap ~1TB 12x80GB NAS NetApp ~.5TB 8x70GB NAS Maxstor ~2TB 12x160GB NAS IBM TotalStorage ~360GB 10x36GB NAS

Hardware Homogenous machines leads to quick response through reallocation HP desktop machines, 320MB RAM, 3u high, 4 100GB IDE Drives $4k/TB (street), 2.5processors/TB, 1GB RAM/TB 3 weeks from ordering to operational Slide courtesy of Brewster Archive.org

Disk as Tape Tape is unreliable, specialized, slow, low density, not improving fast, and expensive Using removable hard drives to replace tape’s function has been successful When a “tape” is needed, the drive is put in a machine and it is online. No need to copy from tape before it is used. Portable, durable, fast, media cost = raw tapes, dense. Unknown longevity: suspected good. Slide courtesy of Brewster Archive.org

Disk As Tape: What format? Today I send NTFS/SQL disks. But that is not a good format for Linux. Solution: Ship NFS/CIFS/ODBC servers (not disks) Plug “disk” into LAN. –DHCP then file or DB server via standard interface. –Web Service in long term
