Setting vDisk boot menu as a default option

Branch repeater 6.1 released to web

Citrix has released today version 6.1 of it’s Branch Repeater software.

The following enhancements are available in this release.

  • Repeater VPX is now supported on Microsoft’s Hyper-V hypervisor running under 64-bit Windows 2008 R2 SP1, in addition to XenServer and VMWare vSphere. The features and specifications of Repeater VPX under Hyper-V are the same as those under the other hypervisors. See chapter 7.
  • The Windows file system (CIFS) and Outlook/Exchange protocol (MAPI) are now supported with NTLM 2 and Kerberos encryption, allowing traffic on Windows domains running with the default security settings to be accelerated. Previously, only NTLM 1 encryption was supported, and NTLM 1 is not enabled by default in Windows domains. These features are available automatically whenever the appliances have joined a Windows domain and have designated a Kerberos delegate user. See section 4.19.
  • The Windows file system (CIFS) and Outlook/Exchange protocol (MAPI) now support encrypted traffic involving multiple domains, such as when the client is a member of and the server is a member of, provided that the appliance, the client, and the server are all members of domains that have established mutual trust. This feature is available automatically when the appliance has joined one of the mutually trusting domains. See section 4.19.
  • The Repeater Plug-in is now supported in release 6.1. Previously, it was supported only in release 5.x. New features include enhanced CIFS and MAPI support, matching those of the appliances, when appropriate security credentials are installed on the Plug-in. See chapter 6.
  • To reduce the resources used on routers supporting the appliance in WCCP mode, the WCCP “MASK” option now uses a single-bit mask. The previous multibit mask could reduce performance on routers and smart switches with limited resources. This behavior is automatic. See section 4.13.

Citrix PVS 6.1 HF1 (CPVS61E001) upgrade path

If you haven’t installed the latest hotfix for Citrix Provisioning Services 6.1 yet (be ashamed ). But not to worry when you are working with version 5.6 (or lower, again be ashamed…) you can upgrade your PVS server directly to PVS 6.1 with HF1. You do not need to install PVS 6.1 and then install HF1 over this installation. As the HF1 is a complete installation of your PVS software you can directly upgrade to this version.

For the target side you can install the target device software and copy a few files manually (when having the vDisk in maintenance mode) and your done.

You can read more about the patch here or see the installation step-by-step guide here.
