Diskeeper takes wraps off V-locity 3 Virtual Platform Disk Optimizer

By ECM Plus staff

ECM Plus +++ Diskeeper has just released the latest version of V-locity 3 virtual platform disk optimizer for VMware, proffering invisible background optimisation for maximum I/O performance on virtual servers.

According to Diskeeper, V-locity 3 now boasts full integration with VMware ESXi, together with ongoing support for other platforms, such as ESX, and MS Hyper-V.

Other new features include V-Aware, which detects external resource usage from other virtual machines on the virtual platform and can eliminate resource contention that would otherwise exist on the same Host Server.

Version 3 also offers a new, so-called ‘CogniSAN’ technology which detects external resource usage within a shared storage system, such as a Storage Area Network (SAN), and enables transparent optimization by never contending for resources uutilized by other VMs over the same storage infrastructure. CogniSAN does this without intruding in any way into SAN-layer operations. Lastly is the new automatic space reclamation which is a powerful engine that zeros out unused data blocks on virtual disks and makes virtual disk compaction easy.

Diskeeper described V-locity 3 as ‘like a virtual doctor that eliminates many of the chronic pains servers experience’, and the ‘I/O bottlenecks, slow VMs, slow migration, resource conflicts, wasted storage space, slow backup speeds’.

V3 now offers faster VM and host I/O throughput
Increased VM density; increased platform reliability
Eliminated resource contention; optimized VM resource usage within a shared storage system; increased hardware life
Lowered operating costs; all done fully automatic and transparently.

New Features include V-Aware detects external resource usage from other virtual machines on the virtual platform and eliminates resource contention that would otherwise exist on the same Host Server; CogniSAN detects external resource usage within a shared storage system, such as a SAN, and allows for transparent optimization by never competing for resources utilized by other VMs over the same storage infrastructure. Important: CogniSAN does this without intruding in any way into SAN-layer operations.

V3 also now features Automatic Space Reclamation, an engine which zeroes out unused data blocks on virtual disks and makes virtual disk compaction easy. It also enables VMotion (VMware) or Live Migration to compact a disk on‑the‑fly when they migrate virtual disks. Automatic Space Reclamation occurs online with no need for a maintenance window.

Diskeeper confirmed that Special Virtual Disk Auto Detection is also now included, which enables each V-locity 3 ‘guest’ to conform its optimization settings to the type of virtual disk/features the VM is using, such as dynamic/thin disks and linked clones, for maximum performance.

V3 consists of two core components: V-locity 3 Guest installs on all Windows virtual machines. V-locity 3 Host Agent installs on any Windows virtual machine over VMware ESX/ESXi, or directly on the Hyper-V hypervisor. Host requires Windows 2008 (R2) server with Hyper-V role. VMware: ESX and ESXi server versions 4.0 or later. Guest supports the following OS’s: Windows XP (requires SP2), Windows Vista, Windows 7, Windows Server 2003, Windows Server 2008 (or R2).
