FusionStorm Acquires CentriServ
8. January 2010 by Tony.
Adds Expertise to Client Virtualization Practice Assisting IT Departments With Architecture and Design and Fully-Hosted Managed Virtual Client Solutions
SAN FRANCISCO, CA–(Marketwire - January 6, 2010) - FusionStorm — “Making Technology Work” — a leading systems integrator and managed services provider announced today that it has acquired CentriServ of King of Prussia, Pennsylvania.
CentriServ specializes in consulting and implementation services for server-based, virtual-client computing, which streamlines delivery of IT resources, centralizes IT management and simplifies applications access for end users. The company is an authorized solution partner for Citrix, Microsoft, VMware and other vendors delivering technology for client virtualization.
The acquisition enhances FusionStorm’s ability to deliver enterprise-class client virtualization to its existing customer base. The company will architect, design and deliver these solutions for customers who are running their own IT systems. FusionStorm will also offer fully-hosted and managed virtual client solutions in “desktop-as-a-service” and “software-as-a-service” cloud computing models.
In addition, CentriServ clients now have access to many more technology solutions from FusionStorm’s broad and deep technology practices, including networking, data center, storage, collaboration, unified communications, business continuity, managed services and managed hosting.
John Varel, CEO of FusionStorm, states, “This is an important acquisition for FusionStorm, and we are excited about what CentriSev brings to the FusionStorm team. Their talent and experience in client virtualization strengthens our ability to deliver these high-demand solutions to our customers.”

NetScaler MPX vs. VPX – differences
29. December 2009 by Tony.
The NetScaler VPX virtual appliance has some decisive differences from its MPX hardware counterparts. While the performance differences are well documented, some of the finer networking related points are a bit obscure and not readily discoverable. While none of them are likely to be show stoppers, it’s important to be familiar with the limitations.
Here’s a short table I’ve assembled describing the impact of the hypervisor on the NetScaler virtual appliance as compared to the network stack of the MPX:
| MPX | VPX |
| Native 802.1q VLAN Tagging | Tagging is defined on the hypervisor. XenServer is limited to 7 tagged networks and 16 on VMware. |
| Native 802.3ad Link Aggregation | 802.3ad is not supported by XenServer. Source Level Balancing (SLB) NIC bonding is the closest parallel and offers NIC redundancy with great performance. But not all switches work well with SLB so be sure to test under load, plug both links into a single switch, or skip SLB entirely in favor of native NetScaler device failover. |
| Device Fail-over | Failover is supported between VPX devices through NetScaler’s native redundancy mechanism. So there’s no need for XenMotion or VMotion support with the VPX. |
| Dedicated SSL Chipset | No SSL chipsets are available to the VPX, but none the less, it is capable of 300 3DES and 1000 RC4 sessions. At double the VPN capacity, VPX makes a great upgrade path from Secure Gateway by providing a full SSL-VPN, Smart Access, and improved security. |
Licensing Changes in VPX 9.1 Build 100.3:
For VPX appliances only, the 9.1_100.3 license software will check the MAC address of the FIRST INTERFACE listed. In previous builds, the license software checked the MAC address of the NEWEST INTERFACE. For VPX customers who upgrade to 9.1_100.3, this change will invalidate licenses on VMs which had more than one interface. They will need to revisit MyCitrix.com licensing portal to re-host their license. CTX122426 – NetScaler VPX Licensing Guide has been updated with the rehosting instructions.
VPX owners are allowed to relicense their VPX system up to 3 times.

Will Oracle buy Citrix?
29. December 2009 by Tony.
[According to the Briefing.com financial news site, software giant Oracle - not even finished with its $7.4bn acquisition of Sun Microsystems - is sniffing around middleware and virtualization maker Citrix Systems and may be interested in acquiring the company.
That Oracle would be interested in buying Citrix is totally plausible. Oracle has its own implementation of the open source Xen hypervisor. When it became clear that Red Hat was going to shift to the KVM hypervisor, Oracle looked around for another set of Xen tools and snapped up Virtual Iron, which had its own variation on the Xen theme. But in August 2007 Citrix bought XenSource.] Full Story Here
