Adaptec ASR-71605 Low Profile RAID Controller Card

Adaptec ASR-71605 is a 16-port SAS/SATA RAID controller card in a low-profile MD2 form factor, intended for internal use in servers and storage enclosures. It plugs into a PCIe 3.0 x8 bus and delivers 16 SAS/SATA 6Gb/s channels via four internal mini-SAS HD (SFF-8643) connectors, enabling dense drive configurations in compact chassis. The card includes 1 GB of DDR3 cache to accelerate RAID operations and supports RAID levels 0, 1, 1E, 5, 6, 10, 50, and 60, making it suitable for a range of protection schemes from simple mirrors to dual-parity arrays. A Battery Flash Module is included to preserve cached data in power-loss events, helping protect writes during outages. With the MD2 low-profile bracket included, it fits in small-form-factor servers, and it supports Adaptec management tools (BIOS Configuration Utility and CLI) and common operating systems such as Windows, Linux, Solaris, and VMware, per Adaptec catalog offerings.
