A New White Paper from Winchester Systems; ''Enterprise RAID 6'' Data Protection.BURLINGTON, Mass. -- Winchester Systems Inc., a leading data storage solutions company, today announced the availability of a new white paper entitled, "Enterprise RAID 6." The paper is about the added protection of RAID 6 versus the typical RAID 5 arrays shipping today and the importance of improving data protection. The Enterprise RAID 6 paper addresses the issue of protecting against data loss after a drive failure in today's large disk arrays. Large arrays require very lengthy rebuilds to restore the array to full operation. For a successful rebuild to occur after a typical RAID 5 disk drive failure, every block on every surviving disk drive must be readable. Larger arrays are more vulnerable to a rebuild failure due to the sheer number of blocks to be read.

More importantly, it continues to provide parity protection after a single drive failure - to protect your data during rebuild. That capability simply does not exist in any RAID 5 array." He emphasized, "This extra protection is more than just nice - it results in typically a 1000-fold improvement in MTDL - from months to millennia." Their chief technology officer, Mr. Jerry Namery, stated, "Our Enterprise RAID 6 products use dual hardware ASICs to speed RAID 6 parity calculations so that our RAID 6 arrays are about as fast as our RAID 5 arrays and faster than most RAID 5 offerings - yet cost less than RAID 5 from other companies." Thus we have developed products that offer an overwhelming improvement in data protection and maintained full speed operation at lower cost - a tremendous overall value," he added. The company's Enterprise RAID 6 arrays start at under $10,000 and delivery is 2 to 4 weeks. The free white paper is available on the company's web site at: www.winsys.com.
