Due to an increasingly distributed IT environment, it is vital that server virtualization solutions including VMware virtual infrastructure span multiple data centers. However, one of the challenges of implementing distributed processing technologies and server virtualization across geography (e.g., for the purposes of VMotion migration or VMware High Availability) is the issue of data locality. In order for two or more sites to share compute resources on-demand, they must also be able to access each other's data on-demand. The GSX 3000s Fully Active operations provide the unique capability of exporting a shared and consistent data image to all servers across sites, while providing local performance.
In addition to reducing TCO and optimizing IT infrastructure, Government legislation and the requirement for 24x7 operations are driving enterprises to reduce both Recovery Time Objectives and Recovery Point Objectives (RTO, RPO).
VMware HA (High Availability) can be deployed on a GSX 3000 multi-site system to provide a powerful and cost effective solution for business continuity. Additionally, the GSX 3000 offers Fully Active, geographically aware fail-over and fail-back, capable of delivering an RTO, RPO of zero across the virtual infrastructure.
When deployed in conjunction with the GSX 3000, VMware HA is promoted into an over-arching high availability and business continuity service that acts to protect all sites within the distributed data center against both server failures and site failures. For example, in the event of a storage failure in the virtual infrastructure, local I/O automatically fails-over to the nearest surviving mirror. Even in the event of a total site failure, the GSX 3000 enables VMware High Availability to failover virtual machines from VMware ESX Servers at a failed site to ESX Servers at a surviving site with minimal interruption in service. In addition to high availability, the GSX 3000s data migration software can complement VMware virtual machine migration software (VMotion).
The GSX 3000s Fully Active operations provide a globally consistent data image across distributed VMware ESX Servers. This enables VMware VMotion, HA, and DRS to be implemented across multiple distributed sites. In addition to enabling virtual machine migration across sites, the GSX 3000 provides powerful data migration software that enables migration of data across a heterogeneous storage environment, while applications remain online Just another example of how YottaYotta's storage virtualization can complement server virtualization environments.
