Intel® RAID SSD Cache Controller RCS25ZB Family

PCIe* Gen3 RAID with Embedded High-performance Flash*

Key features

  • LSI SAS 2208* RAID-on-chip (ROC) controller providing SAS 2.0 compliance, including 6 Gb/s data transfer
  • Up to 1 TB of enterprise multi-level cell (eMLC) NAND flash to significantly enhance the read and write performance of many server applications
  • Embedded 1-GB 1333-MHz cache ECC DDR3 memory for further performance enhancement
  • One SFF-8087 SAS/SATA connector for up to four internal ports and up to 128 hard disk drives (HDD) via expanders
  • Speaker to deliver audible alerts
  • Eight PCI Express* Gen 3 interfaces for fast communication with the server board
  • Optional: Intel® RAID maintenance-free backup to protect data in the embedded DDR3 in the event of power loss or system failure
  • Optional: Cable kit AXXCBL650MSMS includes 2 x 650 mm cables with mini-SAS (8087) to mini-SAS (8087) connectors (AXXCBL740MS7P with mini-SAS to 7-pin connectors also available)

Target applications

The Intel® RAID SSD Cache Controller RCS25ZB family uses intelligent caching algorithms to help identify frequently accessed data—or “hot spots”—and to promote them to the fast onboard flash memory. Solid-state drive (SSD) caching RAID acceleration can be more cost effective than direct-attach SSD-only arrays or short-stroked hard disk drive (HDD) environments.

Key Advantages

System design flexibility 1U-capable system board connects to the I/O expansion slot on Intel’s rack-optimized server boards. This module can be used in Intel and third party chassis without the need for a riser card or low-profile chassis cutout.
Exceptional data protection 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).
Excellent performance LSI SAS 2208* RAID-on-chip (ROC) technology, PCI Express* x4 host interface, and 667-MHz cache enhance the performance of mainstream applications.
Outstanding availability Delivers proactive drive monitoring and automatic error correction. An optional battery backup maintains data without the need for an uninterruptible power supply.
Increased IT productivity Includes a suite of tools that are common across all Intel's SAS/SATA RAID solutions, for easy installation and advanced management.
