For Existing CC-SG Customers It's Easy to Migrate to a Virtual CC

May 24, 2011

My last few blog posts have focused on the benefits of deploying the CommandCenter Secure Gateway as a virtual appliance (VA). Now, with the release of CC-SG 5.1, it’s time to talk about how CC-SG hardware appliance users are shifting over to a “virtual CC”.

First, a quick review… In November 2010, Raritan made CC-SG 5.0.5 available as VA — thereby providing customers with two deployment options: physical (i.e. hardware) or VA. Version 5.0.5 was the vehicle for delivering “Virtual CC” to the market; 5.0.5 firmware does not run on the physical appliance.

Now back to the future. I specifically mentioned release 5.1 above because this is the first version of CC-SG firmware that can run on either the physical or the virtual appliance. Because of this, the two appliance types are interoperable and the CC-SG database of one 5.1 unit can easily be copied over to another 5.1 unit — physical or virtual.  As a result, physical appliance owners now have an easy avenue toward moving to a virtual appliance if desired.

How to Calculate Current on a 3-phase, 208V Rack PDU (Power Strip)

Problem Statement

In recent years, extending 3-phase power distribution all the way to server cabinets and racks has become extremely popular in new data center builds—for many good reasons. Principally, for cabinet power capacities above 5kVA, utilizing 3-phase rack power strips can significantly reduce the copper required to supply such dense loads.

But unfortunately, many users (rightly) find it cumbersome to provision and calculate current (amperage) for 3-phase power in the rack—for example, a typical question would be:

Dominion KSX II Firmware Update - Release 2.3

The Dominion KSX II combo KVM/IP and secure console server has been upgraded to include all KX II Release 2.3 features, except tiering/cascading.  This includes FIPS 140-2 encryption, Smart Card/CAC and other security features, making it ideal for government, military and other security conscious customers.

The KSX II supports 4 or 8 “true serial” connections for remote/branch office deployments, as well as racks requiring both KVM and serial connections.  A “true serial” connection gives secure console access over IP without the use of an expensive dongle.   In addition,  third party SSH clients can be used in addition to Raritan’s Serial Client with features such as logging, cut and paste, and secure chat.

If you have branch offices or racks with serially and KVM controlled devices then the Dominion KSX II can give you anytime/anywhere KVM and serial remote access.

Bandwidth Usage for KX II HD 1080p Resolution?

January 7, 2011

A customer recently asked how much bandwidth the Dominion KX II KVM-over-IP access uses, specifically for the full HD (1920x1080) resolution.  This is a common user question.  The answer is as follows.

There is no fixed bandwidth for the KX II products. The bandwidth depends on how much change there is on the video screen at a particular instant. So if there is no change on the screen, then there will be no or very small amount of bandwidth. If the user is playing a movie, then there could be a very large bandwidth. Of course with larger video resolutions, then there will be more bandwidth than with a smaller resolution.

There is a feature in the KVM clients to see the amount of bandwidth being used. This can be used to check the bandwidth.  There are several settings to decrease bandwidth, as well as some helpful tips on managing bandwidth in the KX II User’s Guide called ‘Bandwidth and KVM-over-IP Performance’ that the customer may find useful.

Raritan Europe installs CC-SG virtual appliance

December being the month that you normally give and receive gifts, this year the welcome present we received this was the news of the virtual edition of the Command Center Secure gateway becoming GA.

For us this was long awaited news, and we were eager to replace the physical appliances we were using in the past on both the IT department, and the local Sales support demo rack.

Nothing against the physical appliance, but since we already made the jump to virtual a couple of years back (we migrated to VMware infrastructure 3.5 in 2008), and we know how much easier it is to maintain and backup a virtual appliance.)

And also the idea of getting rid of two hardware devices to reduce our power consumption, yes that was certainly appealing.
