High Speed IP SAN with Powerful Scalability

Aberdeen furnishes all its XDAS D-Series iSCSI 10G-to-SAS/SATA models with two 10GbE iSCSI ports on each controller and a new SAS2.0 6G hard drive backplane. When data grows out of the capacity threshold of a single subsystem, you can scale it up to an installation housing more than one hundred drives through expansion enclosures. Powered by the new-generation RAID engine as its heart, the new D-Series iSCSI-to-SAS/SATA Series can deliver outstanding performance for processing large amounts of data.


High-Availability SAN Delivers Great Price-Performance

Data availability is critical to any business operation. Aberdeen's XDAS D-Series storage solution features high-availability hardware designs with redundant, hot-swappable hardware components, such as RAID controllers, power supplies and cooling fans to eliminate single point of failure. Hardware RAID protection ensures data accessibility during drive failure. In the event of a power outage, CacheSafe technology will automatically leverage power of the Battery Backup Unit (BBU) to safeguard cached data by writing it to the flash module for permanent retention. To protect valuable data sets against more critical threats, the D-Series also supports local and remote replication capabilities.
