Hyper-V Backup software : Altaro

June 29, 2011 Leave a comment

In January I was contacted by David Vella, CEO of Altaro to provide some feedback about a new Hyper-V backup software.

Altaro Hyper-V Backups works on Windows 2008 R2 (all editions, including core installation) and should be installed on the Hyper-V Host, not within the guest.

Yesterday, I receive a beta copy to test and I will post here my feedback, later. Anyway, my collegue MVP Hans Vredevoort post a good review in his blog with Femi Adegoke help.

For Hans Vredevoort review

http://www.hyper-v.nu/archives/hvredevoort/2011/05/altaro-hyper-v-backup-review/

Interested ? Here http://www.altaro.com/hyper-v-backup/ you can download the installation.  The install size is only 14 Mb in size.

Validate SCSI Device Vital Product Data (VPD) test fails after you install W2008 R2 SP1

June 22, 2011 Leave a comment

If you found this error :” Failed to get SCSI page 83h VPD descriptors for cluster disk
<number> from <node name> status 2″ after applying SP1 to your W2008R2 cluster, Microsoft has released a fix for it.

The List Potential Cluster Disks storage validation test may display a warning message that resembles the following: “Disk with identifier <value> has a Persistent Reservation on it. The disk might be part of some other cluster. Removing the disk from validation set”

The  hotfix resolves an issue in which the storage test incorrectly runs on disks that are online and not in the Available Storage group.

More details:

You configure a failover cluster that has three or more nodes that are running Windows Server 2008 R2 Service Pack 1 (SP1).

You have cluster disks that are configured in groups other than the Available Storage group or that are used for Cluster Shared Volumes (CSV).

These disks are online when you run the Validate SCSI Device Vital Product Data (VPD) test or the List Potential Cluster Disks storage validation test

Window 7 as Guest OS for VDI : Max Virtual Processors Supported

June 14, 2011 Leave a comment

Looking to implement a VDI scenario with Windows 7 as the guest with a 12:1 (VP:LP) ratio ? With the launch of the SP1 for W2008R2, Microsof increased the maximum number of running virtual processors (VP) per logical processor (LP) from 8:1 to 12:1 when running Windows 7 as the guest operating system for VDI deployments

Formula :  (Number of processors) * (Number of cores) * (Number of threads per core) * 12

 Virtual Processor to Logical Processor2 Ratio & Totals

1Remember that Hyper-V R2 supports up to a maximum of up to 512 virtual processors per server so while the math exceeds 512, they hit the maximum of 512 running virtual processors per server.

2A logical processor can be a core or thread depending on the physical processor.

  • If a core provides a single thread (a 1:1 relationship), then a logical processor = core.
  • If a core provides two threads per core (a 2:1 relationship), then each thread is a logical
    processor.

CentOS now have official support as guest VM in Hyper-V

May 18, 2011 2 comments

Effective immediately, Microsoft will support Windows Server2008 R2 Hyper-V to run CentOS.  

CentOS is a popular Linux distribution for Hosters, and this was the number one requirement for interoperability that we heard from that community.

This development will enable MS Hosting partners to consolidate their mixed Windows + Linux infrastructure on Windows Server Hyper-V; reducing cost and complexity, while betting on an enterprise class virtualization platform. .

How will support work?
Call Microsoft CSS. Support will cover installation issues as well as configuration issues.

What version of the Linux Integration Services support CentOS?

 The existing Hyper-V Linux Integration Services for Linux Version 2.1 support CentOS. The following features are included in the Hyper-V Linux Integration Services 2.1 release:

· Symmetric Multi-Processing (SMP) Support: Supported Linux distributions can use up to 4 virtual processors (VP) per virtual machine.

· Driver support for synthetic devices: Linux Integration Services supports the synthetic network controller and the synthetic storage controller that were developed specifically for Hyper-V.

· Fastpath Boot Support for Hyper-V: Boot devices take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.

· Timesync: The clock inside the virtual machine will remain synchronized with the clock on the host.

· Integrated Shutdown: Virtual machines running Linux can be gracefully shut down from either Hyper-V Manager or System Center Virtual Machine Manager.

· Heartbeat: Allows the host to detect whether the guest is running and responsive.

· Pluggable Time Source: A pluggable clock source module is included to provide a more accurate time source to the guest.

The Linux Integration Services are available via the Microsoft Download Center here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=eee39325-898b-4522-9b4c-f4b5b9b64551

 From Wikipedia:

CentOS is a community-supported, mainly free software operating system based on Red Hat Enterprise Linux (RHEL). It exists to provide a free enterprise class computing platform and strives to maintain 100% binary compatibility with its upstream distribution. CentOS stands for Community ENTerprise Operating System.

Red Hat Enterprise Linux is available only through a paid subscription service that provides access to software updates and varying levels of technical support. The product is largely composed of software packages distributed under either an open source or a free software license and the source code for these packages is made public by Red Hat.

CentOS developers use Red Hat’s source code to create a final product very similar to Red Hat Enterprise Linux. Red Hat’s branding and logos are changed because Red Hat does not allow them to be redistributed.

CentOS is available free of charge. Technical support is primarily provided by the community via official mailing lists, web forums, and chat rooms. The project is not affiliated with Red Hat and thus receives no financial or logistical support from the company; instead, the CentOS Project relies on donations from users and organizational sponsors.
