XenServer 5.6 Feature Pack 1 Beta – storage consumption problem solved

October 27, 2010 2 comments

You remember my posts about XenServer storage consumption? The problem is, that after deleting a snapshot the space on the storage is still in use, this is really annoying and you have to reclaim the space manually by typing a command in the XenServer console or use my Powershell script.

Now the game has changed, XenServer 5.6 FP1 Beta is finally able to reclaim the space after deleting a snaphot! Feel free to test the FP 1 Beta and try it yourself! I’m glad Citrix has finally solved this problem, many XenServer customers had massive problems with this “issue”, let’s hope the final Feature Pack becomes available soon.

Citrix Access Gateway 5.0 and Access Controller available for download

October 27, 2010 1 comment

Today Citrix released CAG 5.0 and the new Access Controller Software (formerly known as Advanced Access Control). You can download the VPX for XenServer/VMWare, the Access Controller for Windows 2008/2008 R2 and an ISO image/upgrade image for the model 2010 hardware appliance here (MyCitrix account required).

In my post “Access Gateway 5.0 a deeper look Part 1” I already informed you about the new features and the basic configuration of the CAG, part 2 is coming soon, it’s about configuring the CAG for remote access. Part 3 will concentrate on the Access Controller, so stay tuned…

Access Gateway 5.0 – a deeper look – Part 1

In my post Access Gateway 5.0 on the way I gave you a quick overview of the new CAG 5.0. This new release will be available soon at the end of October.

So now is the time to look more closely… First here are the new features of Access Gateway 5.0:

Access Gateway 5.0 on the way

October 10, 2010 Leave a comment

In Berlin I took a deeper look on CAG 5.0. I looks very smart, a complete new admin interface and user experience. Jay Tomlin from Citrix showed me the improvements and changes.

There will be no “Standard” and “Advanced” edition any more, like we know it from now. You can do lots more with only the appliance but without an Advanced Access Control server. The AAC server is still present and only runs on Windows 2008 R2, but not necessarily required.

The admin interface is browser based and runs with flash. All the net6 stuff is thrown overboard. The login page looks very nice, but at the moment the admin can’t do any customization, this will be possible later next year. There are improvements in the authentication progress and endpoint analysis.

The CAG VPX (virtual appliance) will run on XenServer and VMWare, probably on Hyper-V next year. In the future Citrix plans, to introduce the new GUI to all VPX products, like NetScaler/Access Gateway Enterprise.

CAG 5 will be available at the end of October, I can’t wait to implement it…

Powershell script for cleaning up space after deleting snapshots from VM’s

September 1, 2010 1 comment

You remember my two posts about the snapshot and missing free space on the storage after deleting a snapshot. With XenServer 5.6 Citrix changed the command to free space to a xe command. This makes it easy to write a script, that frees space for all VM’s on your XenHost after deleting snapshots. Here it is:

    Configuring an LACP bonded Interface with Cisco switches

    June 7, 2010 1 comment

    I found this interesting article on the QuorumSoft website:

    Configuring an LACP bonded Interface with Cisco switches

    The default bonding mode for Citrix XenServer 5.5 is 1, or active-backup (slb).  This mode only provides fault tolerance, since only one NIC in the bond is active at a time.  For more heavily utilized production systems, an active-active configuration is preferable.  The two bonding modes that provide full send/receive balancing across all NICs are 4 (802.3ad) and 6 (alb).  Mode 4 provides link aggregation according to the 802.3ad specification, and requires an etherchannel to be configured on the switch.
    The following is an example of how to configure an LACP/802.3ad bond with XenServer 5.5 and a Cisco 3750 switch running IOS.
