Overview
IBM continues to demonstrate leadership in business continuance, offering Peer-to-Peer Remote Copy (PPRC) over Fibre Channel links for the IBM TotalStorage® Enterprise Storage Server(TM) (ESS), and enhancements to the ESS Application Programming Interface (ESS API).
The use of Fibre Channel as the communications link between the ESS PPRC primary and PPRC secondary machines drive business efficiency by enabling the exploitation of existing Fibre Channel infrastructure and capacity. Compared to PPRC over ESCON® links, PPRC over Fibre Channel allows a reduction in the PPRC link infrastructure by a 4 to 1 ratio, while delivering equivalent or better performance.
The ESS API is enhanced to support Copy Services configuration and use for PPRC and FlashCopy®. It supports these activities through the use of the interface as defined by the Storage Networking Industry Association (SNIA) Storage Management Initiative Specification (SMI-S). These enhancements demonstrate IBM's continued support for Common Information Model (CIM) and Web Based Enterprise Management (WBEM) technologies as the common interface for the discovery and management of resources in a multi-vendor storage area network.
Arrays Across Loops (AAL) is a new configuration option whereby disk arrays are spread across both loops on the SSA device adapter pair. AAL configurations can support up to a 1.8 times improvement in sequential bandwidth performance on a single array.
Additionally, many ESS users can potentially benefit from the following support enhancements:
o Asynchronous Cascading PPRC enhancements, exploiting failover and failback modes
o rpm intermix support among same-capacity disks, including Spare Upgrades (#219x)
o Turbo II Processor option, offering new levels of throughput and performance for high-capacity configurations
