"The system we have produced for Citi TV includes a PlayBox Technology DataBox Neo server with a 32 terabyte network-attached storage archive including RAID5
The fiber channel disk array is organized in RAID5
using ten disks (Seagate ST3300657SS, SAS, 300GB).
The research found that 79% of RAID0 arrays are recovered within an hour while 93% of RAID5
arrays require 48 hours to complete.
In addition to SGI DMF tiered storage virtualisation, other key components of the solution include a pair of SGI InfiniteStorage 4600 RAID disk arrays with a combination of 8Gbit FC and 10Gbit iSCSI host ports, FC RAID5
(tier1-50TiB) and SATA RAID6 (tier2-400TiB) drives, a group of front-end, control and infrastructure servers based on SGI Rackable C3108-TY11 standard-depth rack-mount servers, an enterprise class SpectraLogic T-finity tape library using LTO5 technology with installed 11 LTO-5 drives, close to 3700 tape slots and initially loaded with 2200 LTO5 tapes, SAN 8Gbit, Ethernet 10Gbit and 1Gbit redundant network infrastructure, SGI CXFS clustered parallel file system and SGI Management Centre software.

Even so, the analytical model of arrays are still under study like in (7) where the performance of a multi-level array architecture is described, or in (8) where model is used for an analyses of disk-oriented rebuild processing in RAID5
Slightly older data, say 9- to 18-months old or 12- to 24-months old, might be pushed to a slower SAN configuration on LUNs configured as RAID5
with just a few spindles.
Other packages include a professional offering - the Quad Core XXL Server - with AMD Opteron 2352 processors, 1,500GB of storage on three hard drives configured as RAID5
and 16GB RAM for GBP119.99 (Windows GBP249.99) for the first six months and GBP119.99 (Windows GBP129.99) thereafter.
For instance, RAID5
, RAID1, and RAID6 can all provide disk redundancy, and the RAID can still process the I/O even when a disk fails.
While the solution ships in RAID5
, providing the best balance between security and available storage space, it also supports RAID 0, 1, 10 and JBOD modes.
Products in the stunning Teatro portfolio include the 'Actor' series, with up to 1Tb storage capability, the 'Director' series, with up to 5Tb of multi-HD streaming storage capability and the ultimate 'Producer' series, which incorporates near silent operation, an extremely powerful quad-core processing engine and 9Tb of RAID5
multi-HD streaming storage.
It also features two Western Digital Raptor drives set in RAID0 configuration for blazing fast speed as well as a RAID5
array of 1.5TB for the userCOs dataC[yen].
