Much of Virtual Iron’s growth has come from small and medium-sized enterprises, which make up about 70% of its customer base. To reach this audience, Virtual Iron says it offers comparable capabilities to VMware but in a package that is much easier to deploy and easier to afford. Both of which typically resonate well with SMBs.“There is tremendous demand worldwide for an alternative server virtualization solution,” said Ed Walsh, president and CEO of Virtual Iron. “We offer all the capabilities of VMware without the cost and complexity. This combination is meeting a very real and fast-growing need in the mainstream market.” Around the same time, Virtual Iron also released an update to its server virtualization product, version 4.3.“In Version 4.3, we continue to make production-class server virtualization better and easier for the mainstream market,” said Chris Barclay, Director of Product Management at Virtual Iron. “For example, Version 4.3 includes the ability to LiveUpgrade, enabling users to upgrade with no VM downtime.” Virtual machine downtime is becoming a big marketing and sales point in the virtualization community. So I’m sure the SMB market will take notice of this feature. Key additions in Version 4.3 include:LiveUpgrade: This provides the ability to perform upgrades from 4.2 to 4.3 without any virtual server downtime. Windows 2008: Support to run the latest Windows server version in virtual servers. Change virtual server CDROM while running: This allows customers to mount and unmount CDROMs, including network CDROMs (ISOs) without needing to stop virtual servers. Experimental iSCSI MPIO: This provides experimental and partial support for iSCSI multi-path, focusing on multiple storage controllers. Jumbo frame support: This improves iSCSI network traffic throughput.Virtual Iron Version 4.3 also adds support for a number of operating systems and updated versions.RHEL 3 U9 32-bit RHEL 4 U6 AS 32-bit and 64-bit RHEL 5 U1 32-bit and 64-bit SUSE Linux Enterprise Server 9 SP4 32-bit and 64-bit CentOS 4 U6 32-bit and 64-bit CentOS 5 U1 32-bit and 64-bit Windows Server 2008 32-bit and 64-bit Windows Vista 64-bitYou can get the new release on Virtual Iron’s Web site.
