    Product Specifications:

The Intel  RAID Controller SRCSASLS4I supports both enterprise-class serial ATA (SATA) and serial-attached SCSI (SAS) disk drives. Supporting dual architectures allows solutions to be customized for performance, reliability, system expansion flexibility, and hard drive capacity.

The RAID Controller SRCSASLS4I provides flexibility and helps lower the total cost of ownership with a standardized server and storage infrastructure.

This RAID controller has four internal SAS/SATA ports and uses a x8 or wider PCI Express* server board slot.

1.2 Operating System Support
  •  Supports SAS/SATA devices at speeds up to 300 MB/second per port
  •  Supports the SATA II protocol over SAS transport
  •  Contains four internal SAS/SATA ports
  •  Supports up to 8 SAS/SATA II devices via expanders
  •  Supports up to 64 virtual disks
  •  Supports up to 8 arrays
  •  Supports RAID levels 0, 1, 5, 6, 10, 50, and 60
  •  Hardware exclusive OR (XOR) assistance
  •  Online capacity expansion
  •  Online RAID level migration
  •  Physical drive roaming
  •  RAID controller migration
  •  Fast virtual drive initialization
  •  Hot-spare drive configuration, both private and global
  •  SATA drive hot-plug
  •  Staggered spin-up
  •  Native command queuing
  •  Support for SMART*
  •  Auto rebuild
  •  Variable data stripe size configured per virtual drive
  •  128 MB of ECC DDR2 667 MHz SDRAM integrated on the controller
  •  Read and write cache policy
  •  SES2 intelligent enclosure support
  •  PCI hot-plug support
  •  Background media test (patrol read)
  •  Background data integrity test
  •  The Self Monitoring Analysis and Reporting Technology (SMART) detects up to 70 percent of
  • all predictable disk drive failures. In addition, SMART monitors the internal performance of all
  • motors, heads, and drive electronics.

 

  •  PCI-Express* interface (x8), 2.5 Gbps
  •  Local 72-bit DDR-II SDRAM interface with ECC checking.
  •  Dual independent internal DMA controllers maximize parallel data movement operations between system memory and any peripheral/block on the processor local bus (PLB), including local external devices such as Flash ROM, NVRAM, etc.
  • Two messaging units. Only one can be enabled per power-on cycle:
  • - Fusion MPT message unit
  • - Proprietary / test message unit
  •  Two I2C interfaces for memory detection and PCI Express* SMBus onnectivity.    Serial boot-strap ROM is also connected here.
  •  Integrated dual UART for MegaRAID* diagnostic use only.
  •  Eight channels of 3 GbpS full duplex SAS / SATA / Tunneled SATA
  •  Two banks of SGPIO signals to accompany the two sets of x4 SAS/SATA ports
  •  PCI Express interface supports x8, x4, and x1 lane configurations
