* * * 3PAR Remote Copy 3PAR Remote Copy is a uniquely simple, efficient and flexible replication technology that allows customers to protect and share data of any application affordably. Implemented natively over IP and with a handful of simple, intuitive commands, 3PAR Remote Copy can be set up, managed, and tested in a matter of minutes. Costly and prolonged professional services engagements, common with other replication technologies, are eliminated. Special extenders or converters that permit long distance replication are also eliminated. With Remote Copy users may flexibly choose to use one or both modes of operation: asynchronous periodic and synchronous (which supports native Fibre Channel connectivity as well). Remote Copy allows users to mirror data between InServ Storage Servers of any model and configuration, eliminating the incompatibilities and complexities associated with trying to mirror between traditional vendors midrange and highend array technologies. Source and target volumes may also be flexibly and differently configured to meet users needs (e.g., different RAID levels and drives types). Special efficiencies stem from the thin copy capabilities of Remote Copy. Since Remote Copy is Thin Provisioning-aware, target volumes provide the same dramatic cost savings and ease-of-use benefits associated with thin provisioned source volumes. Bandwidth is also efficiently utilized since (with asynchronous periodic mode) changed data within a volume or consistency group is transferred only once -- no matter how many times it may have changed between synchronization intervals. * * * For this chart; you want to be in the lower right hand corner – high SPC-1 IOPS? and low response time Note that the IBM SVC 2 x DS8700 result is actually achieved by virtualising two arrays together – comes at a cost of very high price/performance $ per IOPS * HP Confidential * For this chart, you want to be up in the top left corner – high SPC-1 IOPS? and low $ / S
