Striped Data with Distributed Double Parity — RAID 6

RAID 6: Two sets of parity data, P + Q, are striped

across disks. RAID 6 safeguards against data loss

during rebuild mode by allowing up to two consecu-

tive drive failures for maximum fault tolerance.

AMCC' s 3ware 9690SA SAS/SATA hardware RAID controllers deliver industry-leading RAID 6 and RAID 5

performance, expanded scalability, robust fault tolerance, and multi-terabyte capacities. A PCI Express host

interface, StorSwitch™ architecture and sophisticated SAS and SATA II features drive this unrivaled performance.

It's Time for SAS

AMCC builds on established 3ware SATA RAID

leadership to introduce the 3ware 9690SA SAS

controller, the new standard in Serial Attached

SCSI RAID. The 9690SA seizes the moment to

enter the market just as SAS hard drives and back-

planes are more widely available and as enter-

prise infrastructures align to realize the potential

of Serial Attached SCSI. As SATA and SAS tech-

nologies converge, users look to 3ware SATA for

price and performance and to SAS for SAS/SATA

connectivity with expansion up to 128 devices.

The 3ware 9690SA delivers accelerated SAS

performance and the flexibility of internal and

external connectivity.

Connect, Expand, Protect with SAS

End users will enjoy configuration flexibility with

three low profile PCI Express controller options:

eight internal ports, eight external ports, or four

internal/four external ports. Compatibility with

industry standard SAS expanders will maximize

scalability. Each 9690SA SAS controller scales to

support 128 SAS and/or SATA devices.

Advanced 3ware RAID architecture and SAS,

SATA, and SATA II performance features, including

3Gb/s and NCQ, help rocket the 9690SA to RAID

5 and RAID 6 performance heights. An optional

The RAID 6 Difference

RAID 6 eliminates the risk of data loss if a second

hard disk drive fails while the RAID array is

rebuilding. Uniquely, in the 3ware RAID 6 imple-

mentation, two sets of parity are simultaneously

calculated, written, and rotated across all the

drives. This second parity calculation enables the

array to survive up to two drive failures without

losing data, significantly improving fault tolerance.

The 3ware RAID 6 double parity algorithm

maximizes RAID 6 throughput, so that the 9690SA

controllers deliver unequaled RAID 6 write

performance.

Enterprise-class RAID Storage

The 9690SA's advanced RAID features, SAS con-

nectivity, and powerful 3ware performance archi-

tecture make it the ideal controller for applications

that require expanded scalability and the highest

levels of sustained write and read performance.

The 3ware 9690SA is designed for NAS storage,

web servers, cluster servers, supercomputing,

near-line backup and archival, security systems,

and pro audio and video applications.
