Product Description
The Adaptec ASR-3085 is a PCI Express SAS RAID controller specifically designed for external storage connectivity. It supports SATA 3Gb/s drives, allowing users to connect and manage multiple hard drives or SSDs housed in external enclosures. The controller provides robust RAID functionality, including support for RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), and RAID 10 (striped mirrors). This enables the creation of high-performance or highly redundant external storage solutions. Equipped with 256MB of onboard cache memory, the ASR-3085 accelerates RAID operations and improves data throughput, ensuring efficient performance for backups, archiving, or expanding storage capacity. The controller features external SAS ports, which are designed to connect to external JBOD (Just a Bunch Of Disks) enclosures or other SAS-compatible storage devices. This makes it an ideal solution for adding significant external storage capacity to servers or workstations without occupying internal drive bays. With support for up to 128 drives when utilizing SAS expanders, the Adaptec ASR-3085 offers substantial scalability for environments with growing storage needs. Its PCI Express interface ensures a high-speed connection to the host system, while the onboard RAID processor handles complex RAID calculations, minimizing CPU overhead. This controller is well-suited for tasks requiring reliable and high-capacity external storage, such as large-scale data backups, media storage, or disaster recovery solutions.
