Citrix has introduced updates to XenServer, its free virtualization
platform, and to Citrix Essentials for XenServer and Hyper-V, its
virtualization management package.
The new 5.5 release of XenServer, which Citrix began offering as a free download
in February, is designed to provide easier virtualization management
and broader integration with enterprise systems, the company said in
its announcement Wednesday. This includes hooks that allow third-party
products to interact with XenServer to provide full or incremental
in-guest, file backups of virtual machines. Image backups are supported
too.
In addition, it lets admins carry out GUI-based snapshots from the XenCenter management console.
The update supplies new tools to convert virtual machines from VMware's
VMDK format into the VHD format used by Citrix XenServer and Microsoft
Hyper-V. It also lets them switch between common open virtualisation
format packages.
In addition, new search facilities give admins a range of ways
to locate virtual machines, while Active Directory integration brings
XenServer hosts into the enterprise's information repository.
The list of supported guests has grown in the new version of
XenServer to include Suse Linux Enterprise Server 11, Debian 5.0 and
RedHat/CentOS/Oracle 5.3.
As for Citrix Essentials for XenServer and Hyper-V, the new 5.5
version adds the ability to clone and provision XenServer or Microsoft
Hyper-V-based virtual machines across physical and virtual resources.
It also allows third-parties to deliver unified backup and snapshot
features for the VMs.
Citrix said the Essentials update also simplifies the process
of building, testing, sharing and delivering applications throughout an
application's life cycle, including the ability to develop and test
environments across virtualization platforms. According to Citrix, it
also extends XenServer's XenMotion features by enabling automated
movement of live virtual machines across servers based on preset rules
and thresholds, so reducing performance bottlenecks.
The beta version of the new Citrix XenServer 5.5 is available
for download now, with the final version scheduled for release on June
19. Citrix Essentials 5.5 for XenServer and Hyper-V is available now
for download in a beta version and a 30-day trial version. It will also
be released on June 19, with prices starting at $2,500 per server,
regardless of the number of processors.
On Wednesday, Citrix also unveiled NetScaler VPX, a virtual
appliance version of its NetScaler MPX hardware appliance that is
designed to accelerate and secure enterprise web applications. It can
be installed on commodity hardware, the company said. It added that the
move should allow smaller companies to access its technology because
the software appliance can be downloaded from the net and run on a
standard server, making it cheaper to buy.
The company is pitching NetScaler VPX for use by enterprises
and cloud service providers as an on-demand service, as virtual
machines can be deployed quickly deployed as demand increases. The
company has not yet announced prices.
