Scalable Network Attached Storage

Aberdeen’s XDAS RAID series scalable DAS - direct attached storage server specializes in the increasing storage needs of fast-growing environments. As a perfect DAS solution for storage hungry applications, streaming media, and companies using high data transfer, the XDAS RAID series provides excellent performance, high reliability, impressive scalability, greater capacity and cost effective external RAID subsystem. When properly configured, it can provide non-stop service with a high degree of fault tolerance through the use of RAID technology and advanced array management features. Our XDAS RAID system provides not only RAID levels 0,1,3,5,0+1 & JBOD but also RAID 6. It can be managed either through the LCD control panel, RS232 port or Ethernet port (Web Browser-Based Management). It also contains STMP manager monitors all system events and user can select either single or multiple user notifications to be sent via ‘Plain English’ e-mails. The Aberdeen XDAS direct attached storage server is the first iSCSI SAN-ready storage array specifically designed for scalable expansion, ease of integration and improved performance without the over inflated costs of implementing the other's direct attach storage solutions.


What is a RAID 6?


AberSAN by Aberdeen

  • RAID 6 is a dual parity RAID scheme offers data protection. RAID 6, also know as ADG is an extension of RAID 5 array with a second independent distributed parity scheme. Data and parity are striped on a block level across multiple array members and a send set of parity is calculated and written across all drives.

Key Points of RAID 6

  1. Allows for two simultaneous drive failures without downtime or data loss
  2. Higher fault tolerance than RAID 1, 3 or 5.
  3. Ideal for applications requiring large logical drives
  4. Lower implementation cost than Mirroring.
