Solution Highlights:
Disaster Tolerant
two metropolitan/city,
three data centers(two sites in one city, another site in anohter city)
two sites in one city are active-active mode
the third site is diaster recovery site
Solution Includes:
HPE 3PAR StoreServ Storage systems
HPE 3PAR Peer Persistence
Remote Copy
Vmware/Windows/Linux
HPE 3PAR Peer Persistence software allows companies to federate their 3PAR StoreServ Storage systems across geographically separated data centers. This inter-site federation of storage allows customers to use their data centers more effectively by allowing them to move applications from one site to another as per their business need, and more importantly, without any application downtime.
Peer Persistence leverages the robust high availability solutions already available on HPE 3PAR StoreServ systems, and extends it even further by enabling a peer relationship between two 3PAR StoreServ Storage systems located at geographically separated sites. Peer Persistence enables failover/failback between two sites/data centers to be transparent to hosts and without any disruption to applications running on them. Peer Persistence is deployed with Remote Copy without the need for any additional hardware or appliance
Remote Copy Synchronous Long Distance (SLD) topology allows volumes in a Remote Copy volume group to be replicated from one Primary StoreServ array to two different Secondary StoreServ arrays. It does this by replicating data synchronously between two StoreServ arrays, the “source” and “sync target” arrays while simultaneously replicating the same data via periodic asynchronous mode between the “source” and a third array, the disaster recovery, or “async target” array. Asynchronous Streaming Remote Copy is not supported in SLD topologies.
