There are many monitoring solutions on the market, some with specific focus for Citrix environments that tout an "end-to-end" view. But, I've yet to see a single dashboard that shows a user's connection through the NetScaler, Citrix XD/XA, and backend connections to SQL, storage, and other critical components. Splunk can capture data from all of these sources, and index it to your heart's content. But, out of the box you get individual dashboards without the zoomed out view we all crave. That is where Go... read more.

The NetScaler SDX platform is a combination of high performance hardware with a hypervisor tuned to take advantage of it. The solution offers direct mapping of specific components to virtual NetScalers, such as CPU, Memory, SSL cores, and NICs via SR-IOV. But Citrix teased us a while back that the SDX platform may also support workloads other than NetScalers. Citrix has now delivered, working with some third party vendors to offer new workloads on the SDX platform. These are the available products: We... read more.

If you are involved in an InterOrg Exchange migration, you are going to have to migrate your Public Folder infrastructure from the source Exchange organization to the destination organization. Exchange does not offer a native tool to do this. This means you will either have to invest in a third-party utility like the Quest Exchange migration tool or use a free tool from Microsoft called the InterOrg Replication tool (IORepl). As you might expect, the third-party tools are far superior to IORepl, but are als... read more.

Lately, we’ve seen a lot of activity at Gotham clients regarding increasing the functionality their SSL VPN. Gotham has installed a lot of this technology and I was thinking about the early days of SSL VPN.

Many Exchange 2010 administrators are familiar with working with database availability groups (DAG) and the multiple copies of mailbox stores they provide. One area of confusion around DAGs, however, is properly configuring DAG networks. This article reviews how to configure a multi-site DAG that consists of multiple networks. The example I will be using consists of Exchange Servers hosted in two physical locations. Each server has three network cards and resides on three different VLANs. For simplicity,... read more.
