Intel RAID Expander Card RES2SV240 is a 24-port, 6.0Gb/s Serial Attached SCSI (SAS) expander that enables the connection of up to 24 directly attached SAS or Serial ATA (SATA) devices. Each expander phy is individually configurable allowing for either 4 or 8 incoming ports and 20 or 16 outgoing ports, and performs SAS and SATA transfers based on the speed of the host or target at either 6.0Gb/s, 3.0Gb/s, or 1.5Gb/s.

The Intel RAID Expander Card RES2SV240 addresses the growing demand for increased data throughput and scalability requirements across entry level, midrange, and enterprise server platforms.


Key features

  • LSI* LSISAS2x24 SAS/SATA Expander to enable communications with 24-ports at 3 or 6Gb/s
  • Eight SFF8087 SAS/SATA connectors for attaching up to 24 targets or initiators
  • Low profile, MD2 depth for use in low profile slots and motherboards with add-in card depth constraints
  • PCIe x4 connector with power pins to mount and power for a PCIe slot (if desired)
  • RA 4 pin power connector to power form a cable (if desired)
  • Mounting holes for attaching to a chassis or duct wall (if desired)
  • Six SAS cables with SFF8087 connectors at each end and designed

Target applications

Scalable performance

Ultimate flexibility for a high drive count

As the perfect complement for Intels SAS-2 generation RAID cards, this twenty-four port expander card offers ultimate flexibility for architecting a high drive count (greater than 8 drive) storage solution in any sized system. The low profile height enables simple installation into a 1U or 2U system with a low profile chassis cutout. In addition, the MD2-compliant depth (6.6) fits in motherboards with heat-sinks that would interfere with longer add-in cards. In cases where an add-in slot is not available, the Intel RAID Expander Card RES2SV240 can even be mounted to a chassis wall or air-duct.

The RES2SV240, powered by an LSISAS2x24 24-port SAS-2 expander, enables the connection of up to 24 directly attached SAS or Serial ATA (SATA) devices with transfers based on the speed of the host or target at either 6.0Gbs, 3.0Gbs, or 1.5Gb/s. The RES2SV240 can be cascaded to accommodate as many drives as the associated SAS/RAID card allows with table routing for up to 1024 SAS connections. Furthermore, the RES2SV240 supports usability functions such as discovery and enclosure management.


Key advantages

Low-cost alternative to high port count RAID cards

Provides a more economic solution that is similar to a 16 or 20 high port count card, but has more flexibility as the RES2SV240 can be teamed up with a wide variety of 4 or 8 port SAS RAID card/modules to offer features that are best suited to customer needs.

Inside-the-box design flexibility

With a true MD2 form factor; this expander card is ideal for low-profile height and half-length adapter slots. In addition, the card design allows for mounting on chassis walls or ducting. Power can be obtained either from a PCIe slot or a power cable.

Excellent performance

Overall performance of the RES2SV240 is on par with Intels SAS-2 high port count RAID with transfer rates of up to 6Gb/s per port. While todays high port count RAID cards typically include an expander on the card, an RES2SV240-based solution separates the expander from the RAID card for more system design flexibility.
