Xyratex Storage Array RS-4835 - FC Attached SATA RAID Storage Array 48 Bays - Refurbished

Xyratex Storage Array RS-4835

Fueled by radical advances in digital video production, medical screening, CCTV surveillance,

disk-to-disk backup and new requirements for securities compliance, the explosion in digital

content creation continues unabated. The sheer volume and wide range of digital information

present a unique challenge for the storage manager, requiring solutions that deliver low cost

and power efficient, high-performance storage across the enterprise.

Realize Value from Storage 24/7 - Xyratex RAID Solutions

OEMs and solution integrators now require ever more sophisticated systems and

solutions capable of managing and maintaining this vast amount of business critical

data. They are also under considerable pressure to address four key challenges: shorten

time to market; reduce test, integration, warranty and service costs; increase reliability;

and bolster customer satisfaction.

Xyratex RAID solutions reduce development costs, feature enterprise-class RAID

functionality including RAID-6 and Snapshot, support high availability, dual controller

configuration support and are highly reliable.

Redefining Flexibility and Availability – Xyratex F5404E

The Xyratex F5404E was engineered to address these demands, combining 4Gb Fibre

Channel (FC) RAID connectivity with Serial ATA II (SATA) disk drives, and Serial Attached

SCSI (SAS) expansion technology, offering affordable RAID data storage and high

performance capabilities.

The Xyratex F5404E sets a new standard in the design of mass storage enclosures to

provide OEMs with unsurpassed disk storage capacity in a single enclosure. Housing 48

SATA drives in 4U of rack space, the F5404E can store 48TB of data in a single unit. With

a combination of high performance controllers and high-density packaging, the fully HA

design of the F5404E increases the flexibility of storage deployment to the end user.

The Xyratex F5404E provides the bandwidth needs for disk-to-disk backup, archive and

other storage intensive applications, while leveraging SAS full duplex, point-to-point

architecture with dedicated connections for maximum data throughput. There is also

no single point of failure, with two RAID controllers per chassis and host-based dynamic

multi-pathing to maintain continuous access to application data. Meanwhile, the F5404E

has the lowest power consumption (50 percent more TB/KW), and highest density (33

percent more TB/ft2) of any nearline storage RAID system on the market.

Fully populated with 48 500GB 7.2K SATA Hard Drives. (24TB Total)
