Parity checking is also used in communication betweenmodems. Here, parity checking can be selected to be even -- a successful transmission forms an even number -- or odd. Users may also select no parity, meaning the modems will not transmit or check a parity bit. When no parity is selec...
(designated as even parity) and -1 (odd parity). More precisely, parity is defined as the eigenvalue of the operation of space inversion. Parity is a concept that has meaning only for fields or waves and therefore has meaning only in classical field theory or in quantum mechanics.See...
7d+1p is the same as raid5 N+1 meaning that for a raid5 of 8 disks the capacity of one will be used for the parity data so you get the capacity of the remaining 7 as useable space. (raid5 ALWAYS uses the space from one disk in an array of 3 to 'X' disks) don...
In a RAID system that includes more than one array of disks, each array is often identified by a unique drive letter, and in order to access a given file, a user must correctly identify the drive letter for the disk array on which the file resides. Any transfer of files from one disk...
Raising tickets has been mostly useless for us, out of about 20 tickets we've raised with Pro support, only two were resolved. None of them have I ever paid, meaning they're all accepted as bugs. But they never have been resolved....
The Symmetrix architecture operates under a “cache all” policy, meaning that all transfers, i.e. from the host to the drives or from the drives to the host, go through cache. The principal function of the Directors is the movement of data between the host and Global Memory (cache) or...
7d+1p is the same as raid5 N+1 meaning that for a raid5 of 8 disks the capacity of one will be used for the parity data so you get the capacity of the remaining 7 as useable space. (raid5 ALWAYS uses the space from one disk in an array of 3 to 'X' disks) don't worry to...
