RAID Recovery - SATA Controllers to boost up RAID 6 performance
Applied Micro Circuits Corporation (AMCC) launched high-performance 3ware 9650 SATA RAID has turned out to be the best RAID 6 category product. Available in models comprising of two-to-24 ports, it is faster, more reliable and power efficient. It has become possible because the 3ware 9650 [...]
RAID Recovery - Performance issues in RAID
The actual purpose of developing RAID was to protect the stored data by developing an effective fault tolerance system. In course of time, while large chunk of data processing has also become one of the most important aspects; things now matter with RAID are, performance, reliability, availability and fault [...]
RAID Recovery - Reliability issues in RAID
RAID is very much important for improving performance; the main purpose of using it is the protection of important data from critical condition.
Three major factors that spectacularly affect the reliability of disk arrays are:
Un-correctable bit-errors- These kinds of errors generally occur if data is wrongly written or steadily damaged [...]
Read Full Post | Make a Comment ( None so far )RAID Recovery - The need for RAID
RAID is simply the organization of numerous disks into a large logical disk. Disk arrays strip data into several disks and access them in parallel to achieve high performance rate in mass amount of data and higher input/output rates on smaller data access.
Using single disk created problems during sudden [...]
RAID Recovery - Why should we use RAID
RAID (Redundant Array of Inexpensive Disk) was invented by D.A. Patterson, G. Gibson and R. H. Katz at the California University to provide wealth of significance reward and safety against losing important data.
RAID’s greater capacity, overall improved performance, higher data security, integrated capacity, improved availability and reliability are [...]
RAID Recovery - Mirroring
Mirroring is one of the most used and efficient techniques of providing redundancy to the RAID arrays. Striping array is almost always implemented in the RAID configurations in order to increase performance but it does not at all provide fault tolerance or redundancy. In case of a drive failure in an array, [...]
RAID Recovery - Physical and Logical drives and Arrays
In RAID, several hard disks are made into one logical disk. There are quite many ways of doing this and each of these ways have certain advantages and disadvantages over using them as single disks. But it is important to know the difference between the hard drive [...]
