Technical Whitepaper - VMware vSphere VMFS-5 Upgrade Considerations
• Larger single extent volume (64TB)
• Larger Virtual Machine Disks (VMDKs): 2TB – 512 bytes with a new unified 1MB block size
• More and smaller sub-blocks (8KB) to reduce the amount of stranded/unused space
• Improvements in performance and scalability via the implementation of the vSphere vStorage API for Array Integration (VAAI) primitive ATS (Atomic Test & Set) across all datastore operations.
vSphere 5.0 supports both VMFS versions 3 and 5. Therefore, it is not necessary to upgrade your VMFS volumes. However, customers can move to VMFS-5 to benefit from these features. A complete set of VMFS-5 enhancements can be found in the What’s New in vSphere 5.0 Storage white paper.

VMware vSphere Storage Appliance Technical Deep Dive
In the release of VMware vSphere 5.0, VMware also released a new software storage appliance called the VMware vSphere Storage Appliance (VSA). VMware VSA provides an alternative shared storage solution to our Small to Medium Business (SMB) customers who might not be in a position to purchase a Storage Area Network (SAN) or Network-Attached Storage (NAS) array for their virtual infrastructure. Without shared storage configured in a vSphere environment, customers have not been able to exploit the unique features available in vSphere 5.0, such as vSphere High Availability (HA), vSphere, vMotion and vSphere Distributed Resource Scheduler (DRS). The VSA is designed to provide “Shared Storage for Everyone”.

Best Practices Guide - High Performance Data with VMware vFabric GemFire
• vFabric GemFire deployed as an enterprise data management system.
• vFabric GemFire deployed as L2 cache.
• vFabric GemFire deployed for HTTP session management.
• vFabric GemFire deployed as a faster mass data mover—for example, real-time reporting.
This guide provides best practice guidelines for deploying vFabric GemFire. The recommendations in this guide are not specific to any particular set of hardware or to the size and scope of any particular implementation. The best practices in this document provide guidance only and do not represent strict design requirements because enterprise data requirements can vary from one implementation to another. However, the guidelines do form a good foundation on which you can build—many of our customers have used these guidelines to successfully implement an enterprise data fiber for their enterprise applications.
