21. It equals to another layer of RAID structured between multiple disk arrays, which maximizes the performance of disk arrays . 22. It equals to another layer of RAID structured between multiple disk arrays , which maximizes the performance of disk arrays. 23. Protocol analyzers can also be hardware-based, either in probe format or, as is increasingly common, combined with a disk array . 24. Broadly speaking, a " storage system " is also known as a storage array or disk array or a filer. 25. The base configuration of Storage Center includes a disk array controller, disk enclosure, disk drives, connectivity hardware, and software modules. 26. In 2011, EMC introduced the new VNX series of unified storage disk arrays intended to replace both Clariion and Celerra products. 27. Patented in 1994, the Clariion disk array had some interesting features that later became standard in the data-storage and computing industry. 28. Most current VTL solutions use SAS or SATA disk arrays as the primary storage component due to their relatively low cost. 29. Mirroring logical volumes across separate disk array controllers allows the logical volumes to continue to operate should one disk array fail. 30. Mirroring logical volumes across separate disk array controllers allows the logical volumes to continue to operate should one disk array fail.
