Intel RAID SSD Cache Controller

The Intel RCS25ZB040 is a RAID SSD cache controller that boosts storage speed and reliability in servers and workstations that handle databases, virtual machines, or media files with strict performance requirements. Installed in a PCIe x8 Gen3 slot, it introduces a dedicated caching layer that reduces latency and lifts overall throughput, keeping demanding applications responsive even during peak loads.

A dual-core RAID-on-Chip processor works with 256GB of onboard flash to hold the hottest data close to the CPU. This design shortens the path between requests and delivery, so frequently accessed blocks reach applications quickly. If a drive fails, the controller completes rebuilds faster, helping the system regain full redundancy with minimal disruption.

Support for RAID levels 0, 1, 5, 6, 10, 50, and 60 lets administrators balance protection and performance for each workload. The card can manage up to 128 SAS or SATA drives, making it a strong choice for tiered pools that mix solid-state drives with high-capacity hard disks. Compatibility with Windows, Linux, and Solaris keeps the deployment process straightforward across diverse data centers.

Intel supplies both standard and low-profile brackets, so the controller fits full-height rack servers as well as compact workstations. SAS cables are not included, giving you the flexibility to choose the length and connector style that match your enclosure.
