12-port SATA 3.0 Gbps RAID controller with 256 MB cache supporting RAID 0, 1, 5, 10, 50 and JBOD over PCI-X 133 MHz

  • 12 SATA ports expand storage capacity
  • 256 MB cache accelerates RAID performance
  • PCI-X 133 MHz host bus delivers 300 MBps throughput
  • Supports RAID 0, 1, 5, 10, 50 plus JBOD
  • AMCC PowerPC 405CR processor manages array operations

Twelve-port SATA RAID controller

The 3ware 9550SXU-12ML is a new PCI-X storage controller that connects up to twelve SATA 3.0Gbps drives. It provides hardware RAID acceleration through an onboard AMCC PowerPC 405CR processor and 256 MB of installed cache memory. The card fits servers or workstations that still offer a 133 MHz PCI-X slot.

Suits arrays of two drives with RAID 5 or 50

This controller supports JBOD, RAID 0, 1, 10, 5 and 50 across a maximum of two storage devices. Administrators maintaining legacy PCI-X infrastructure will find the feature set complete for small mirrored or striped volumes. Builders who need more than two drives in a single array or who require a PCI Express host interface should consider a different product.

PCI-X 133 MHz host bus

The decisive specification is the 133 MHz PCI-X host interface, which dictates motherboard compatibility and peak bus bandwidth. Verify that the target system provides a matching PCI-X slot before purchase.

Domande su questo articolo

Do I need a PCI-X 133 MHz slot to install the 9550SXU-12ML?

Yes, the controller plugs into a PCI-X/133 MHz slot; without that slot the card cannot be seated or powered.

Will my existing SATA 1.5 Gb/s drives work with this controller?

The card runs at SATA 3.0 Gb/s but negotiates down to 1.5 Gb/s, so older drives will operate at their native speed.

How can I verify the 256 MB cache is active after setup?

Open the 3ware management utility; the dashboard reports the installed cache size and shows it enabled for the configured arrays.
