Virsto launches server/storage virtualization product

Virsto emerged from stealth mode last week with the introduction of software for storage virtualization in Microsoft Hyper-V environments.

In most virtual server deployments, storage resources are matched well. VM sprawl can consume more storage than physical servers and performance problems can reduce server I/O by as much as 80%. Managing storage allocated for virtual servers becomes complex.

Virsto One software installs in the parent partition of Microsoft Hyper-V where it helps users manage storage-intensive workloads and ease the management of provisioning storage and server hardware.

The software is a 10MB Windows program. Configuring it requires the administrator to designate a master node for cluster-wide metadata manager, log device for each physical server and then choosing storage volumes for placement of Virsto One software.

Virsto One is deployed as a plug-in to Microsoft Hyper-V Server 2008 R2 and offers a user interface with PowerShell and standard Windows interfaces. In addition Virsto One is integrated with the Windows Management Interface and as a Microsoft Management Console snap-in.

Virsto One supports any block-level storage technology – iSCSI, Fibre Channel, SAS, etc. The software manages the allocation and placement of the virtual disk content on available storage devices. In a Virsto One enabled data center, a storage device is configured only once at initial installation time. All operational provisioning is done through the Virsto One interface.

Internally, Virsto One journals I/Os from individual VMs and sequentially writes and stores write I/Os addresses.

Virsto One is expected to be available by the end of this month. Pricing is based per socket -- a perpetual license for one to two sockets is $1,250. A 30-day evaluation is available here.
