System Center Virtual Machine Manager 2007 review

Denise Ross — Thu, 05 Mar 2009 11:40:40 +0000

Microsoft Virtual Machine Manager 2007 is a very functional and surprisingly usable piece of software that really does make managing large virtual machine farms much easier. If a storage area network is detected, the VMM server will automatically route large virtual machine copies over the SAN for rapid deployment. An integrated physical-to-virtual (P2V) tool is another useful feature, making it easy to migrate existing servers to the virtual world. Reviewers had very few problems putting Virtual Machine Manager 2007 through its paces and were impressed with Microsoft’s first offering in this area.

VMware Infrastructure 3 (VI3) – Review

Denise Ross — Fri, 27 Feb 2009 12:10:48 +0000

VMware Infrastructure 3 (VI3) solution is aimed squarely at enterprises looking to consolidate full-scale production systems. As such it’s easily the most scalable of the VMware platforms with additional management, load balancing and high availability features, all designed to take full advantage of the underlying virtualisation technology. Installation of the ESX software is simplified in VI3 by a Windows-like, install routine. VMware High Availability (HA) is a worthwhile option, adding automatic failover in the event of a hardware or software problem.

XenServer 5 review

Denise Ross — Tue, 24 Feb 2009 10:14:22 +0000

Citrix’s XenServer is a hypervisor that loads and runs directly on a bare server, rather than as an application on a host OS much like the market-leading VMware ESX server. The processors do need to support Intel VT or AMD-V virtualisation technologies, but that’s not been an issue for some time and anything bought recently will support these as standard. with a slicker interface and lots of new features, including the ability to define metadata to group and tag virtual machines.

Vizioncore esxReplicator 2.0 – Review

Denise Ross — Thu, 19 Feb 2009 10:52:02 +0000

Vizioncore esxReplicator 2.0 is dependent upon the WAN connection as maintaining replicas can become an extremely slow process. Companies wanting to maintain replicas via slow WAN links should make a backup of the VM and send the backup media to the remote site, where it can be restored; esxReplicator can then continue the replication by sending the only new or changed information to the remote site. Reviewers were also disappointed at the way replicas were updated in the tests. For example, replication jobs failed if the target VM was running.

Parallels Virtuozzo Containers 4.0 review

Denise Ross — Fri, 13 Feb 2009 10:54:45 +0000

Parallels’ Virtuozzo Containers 4.0 software doesn’t attempt to emulate the physical machine unlike most hosted virtualization products. Because many of the supporting files and libraries are shared, for example, storage overheads are much lower. This in turn enables Virtuozzo Containers to host a lot more VEs per server than you can virtual machines. Containers can also be deployed quickly with no need to install a new OS every time. Reviewers found creating and managing containers very similar to working with virtual machines except that, because you don’t need to install an OS every time.

Double-Take for VMware Infrastructure review

Denise Ross — Tue, 10 Feb 2009 09:53:50 +0000

Double-Take for VMware Infrastructure suite makes replicas by taking a snapshot of the VM’s disk and sending that along with the original disk to another ESX Server system. After installation, the software runs a wizard to create a new replica. The replication does not appear to run at the maximum speed of the disks or network. Unfortunately switching over to the replica uses a manual process and so requires some experience with VMware ESX Server and VirtualCenter. For example, replicas do not normally appear in the VirtualCenter hierarchy of VMs present on each server.

Vizioncore esxCharter 2.0 review

Denise Ross — Thu, 05 Feb 2009 12:05:42 +0000

Vizioncore esxCharter 2.0 is designed to easily answer such questions for administrators running VI3. The suite uses the Simple Network Management Protocol (SNMP) to gather resource utilisation metrics from the ESX Servers. Perhaps the most interesting feature of esxCharter is the billback module. Experiments with this module suggest there’s still room for improvement. For example, companies will need to research the cost of their hardware and software, and may find the billback reports a little simplistic. The base price for esxEssentials covers one ESX Server CPU.

Zeus ZXTM 4.1 review

Denise Ross — Fri, 30 Jan 2009 09:08:46 +0000

Zeus ZXTM 4.1 is an enterprise-class load balancing system suitable for virtually all TCP/IP-based applications. Despite all the advantages of running server software in the virtual machine format, network I/O is a little less efficient with VMs than on dedicated hardware. However, with its ability to rewrite content, monitor service levels and handle multiple protocols, ZXTM is an extremely powerful suite, and better support for protocols other than HTTP would be welcomed by organizations that need load balancing or advanced routing capabilities for non-TCP/IP applications.

esxRanger Professional 3.1 – Review

Denise Ross — Wed, 28 Jan 2009 08:10:07 +0000

Reviewers found the Vizioncore esxRanger Professional backup suite particularly valuable. esxRanger Pro has three operating modes. Its GUI does not run the jobs – it merely creates a command line for esxRanger Pro’s command line interpreter (CLI), which takes commands and actually runs the jobs. Moreover, it’s not necessary to shut down or even quiesce the VM operating system while making backups. The bottom line is that, as with all backup suites, it’s important to test your backups to ensure they will actually restore if needed.

Sun Microsystems’ VirtualBox desktop virtualization software-Review

Denise Ross — Thu, 22 Jan 2009 06:47:26 +0000

Sun Microsystems’ VirtualBox desktop virtualization software is a surprisingly full-featured, no-cost alternative to VMware Workstation and Parallels Desktop that’s well worth the consideration of software developers looking to test on multiple platforms and of IT managers who are evaluating the strategic value of desktop virtualization. From running business productivity applications to playing downloaded videos, VirtualBox performed without error on reviewer’s test systems. All in all, VirtualBox proved an able hypervisor for running guest OSes with a minimum of fuss and even less money.
