The LUN copy technology is on the basic of SERVER-FREE.
Which component is responsible for connecting to the array to distribute in-band command in HostAgent?
Because SAS is serial SCSI, therefore its transmission rate is usually lower than parallel SCSI.
Configure snapshot on S5000, snapshot also occupy storage space, and take up the same size space with the source LUN.
S5000 configure cache strategy, if use the write back mirroring.Because the mirror operation requires the interaction between two controllers, and the transmission of the datA. Therefore the overall performance is worse than write back mirroring.
To improve performance, hot zone should be distributed in traditional hard disk inside as far as possible, because access data is fast in disk insidE.
