Exceptional ROC performance augmented with
high speed Flash.
In addition to the dual core LSI SAS2208 ROC, up to 1TB of Flash significantly enhances the performance of many mainstream applications.
Advanced capabilities that don’t require you to be
an expert.
Built-in caching algorithms manage data transfer to and from the Flash pool without the need for special code, intimate application data structure knowledge or time spent understanding configuration complexities.
Outstanding data protection and availability.
Supports data redundancy using SAS or SATA hard disk drives through mirroring, parity, and double parity (RAID levels 1, 5, and 6) plus striping capability for spans (RAID levels 10, 50, and 60).
Optimized Flash use for both Reads & Writes.
Many competing Flash caching technologies are limited to Read use and do not allow for Write capability. Writes can be mirrored to help protect against data loss prior to the date being written to the designated RAID array.
Faster rebuild during degraded states.
In adegraded array scenario, the time to optimal performance can be reduced by as much as 75%.
Features
- LSI SAS2208 ROC controller providing SAS 2.0 compliance including 6Gb/s data transfer
- Up to 1TB of eMLC NAND Flash to significantly enhance the read and write performance of many server applications
- Embedded 1GB 1333MHz cache (ECC DDR3 memory) for further performance enhancement
- One SFF8087 SAS/SATA connector for up to four internal ports and up to 128 hard disk drives via expanders
- Speaker to deliver audible alerts
- x8 PCI Express* Generation 3 interface for fast communication with the server board
- Optional Intel® RAID Maintenance Free Backup Unit to protect data in the embedded DDR3 in the event of power loss or system failure
- Optional Intel Cable Kit AXXCBL650MSMS includes 2 x 650mm cables with mini-SAS (8087) to mini-SAS (8087) connectors (AXXCBL740MS7P with mini-SAS to 7-pin connectors also available.)
