VMware vSphere interoperability

Before you plan to ugrade to vSphere 5.0, check out the interoperability tables below.

As an example, you may go ahead an upgrade to vCenter 5.0, but vCenter 5.0 will not work with SRM 4.1, so therefore you will have to plan the upgrade very carefully so that any existing systems to not get affected.

vCenter + SRM








vCenter+ ESX













vCenter + Update Manager

Dell announce VASA for next gen Equallogic SAN

New Dell EqualLogic Storage Platform

  • EqualLogic PS4100 Series — ideal for small-to-medium businesses or remote office locations with growing storage needs. The SANs, supporting up to 36TB in a single array and 72TB in a single group, can scale as storage demands increase by seamlessly adding additional PS4100 or PS6100 arrays into an EqualLogic group.
  • EqualLogic PS6100 Series — designed to provide mid-sized customers with a scalable storage environment, up to 72TB in a single array and 1.2PB in a single group, that can easily accommodate both high-performance and high-capacity drive options. The PS6100 family is ideal for customers looking for a storage solution to support the storage demands of a highly virtualized data center environment where the seamless movement and protection of virtual machines, applications and data is crucial.
  •  EqualLogic FS7500, the company’s latest NAS solution that works with EqualLogic PS Series arrays to deliver the only scale-out, unified storage platform for mid-size deployments. The FS7500 uses the Dell Scalable File System, which offers several advanced features including cache monitoring, load balancing and multi-threading for fast I/O processing.

Support for vSphere5 Storage Awareness APIs (VASA) in next gen of Equallogic Storage

  • Dell EqualLogic Host Integration Tools for VMware 3.1 — provide customers with enhanced storage visibility and datastore management as well as improved performance and availability through tight integration with VMware vSphere 5, VMware vSphere Storage APIs for Storage Awareness, VMware Storage Distributed Resource Scheduler (SDRS), and VMware vCenter Site Recovery Manager™ 5.
  • Dell Compellent Storage Replication Adapter for VMware vCenter Site Recovery Manager 5 — supports automated failback from a disaster event and new workflows for planned migrations and downtime. Dell also is updating its Compellent plug-in support for VMware vSphere 5 to help customers more easily link their Compellent storage environment with virtualized resources.
  • Dell PowerVault Integration with VMware vSphere 5 — adds certification and enables customers to manage multiple PowerVault MD3200/MD3600 series of storage arrays from a single VMware vCenter Server instance using the vCenter Plugin for Dell PowerVault MD. The Dell PowerVault MD storage arrays (iSCSI and Fibre Channel) also support VMware vSphere Storage APIs for Storage Awareness. The PowerVault MD3600f/MD3620f series of storage arrays support VMware vCenter Site Recovery Manager 4.1 and 5 using the Dell PowerVault Storage Replication Adapter (SRA).

What’s New in Site Recovery Manager 5.0

With the new version 5.0 release, VMware has expanded the capabilities of Site Recovery Manager to provide unprecedented levels of protection.   The following are among the significant improvements in Site Recovery Manager 5.0 over 4.1:

 • Completely new user interface

Includes the ability to manage both protected and recovery sites from one interface, as well as more intuitive graphical representations of protected objects, without linked mode.

 • vSphere Replication

vSphere Replication is a VMware proprietary replication engine that copies only changed blocks to the recovery site, ensuring both lower bandwidth utilization and more aggressive recovery point objectives compared with manual, full-system copies of virtual machines. It offers Parallel operation with array-based replication via storage replication adaptors to enable tiered replication offerings.

 • Increased scalability

Site Recovery Manager 5.0 has introduced some changes to the scalability limits of previous versions, offering a larger ceiling of protected systems per instance.

• Planned migration

Prior to Site Recovery Manager 5.0, workflow capabilities included both execution and testing of a recovery plan. With version 5.0, VMware has introduced a new workflow designed to deliver migration from a protected site to a recovery site through execution of a planned migration workflow. Planned migration ensures an orderly and pretested transition from a protected site to a recovery site while minimizing the risk of data loss.

• Re-protection

After a recovery plan or planned migration has run, there are often cases where the environment must continue to be protected against failure, to ensure its resilience or to meet objectives for disaster recovery.

With Site Recovery Manager 5.0, re-protection is a new extension to recovery plans for use only with array-based replication. It enables the environment at the recovery site to establish synchronized replication and protection of the environment back to the original protected site.

• Failback

An automated failback workflow can be run to return the entire environment to the primary site from the secondary site. This will happen after re-protection has ensured that data replication and synchronization have been established to the original site.

• Enhanced dependency definition.

• There is now a faster recovery time if IP customization is required at the recovery site.

• There is now the capability to run callout scripts from within protected virtual machines during a failover.

• There is now the capability to manage the start-up of virtual machines at a more granular level as well as to manage their dependent relationships.
