What's New in DPM 2012

Today was the final day of Tech ED and it was nice to sit along with guys from DPM product group and thanks to Praveen and Prabhu for sharing details on DPM 2012 features. Earlier in the day it was interesting to discuss SCVMM 2012 and Exchange online solutions with Microsoft consultants present at event. Coming Back to DPM, I am going to keep it short and precise about the features in DPM 2012 but as I have worked on almost all versions of DPM since their first 2006 release, I felt good about the way new centralized reporting works in DPM and also the fact that very soon you will be able to deploy DPM agents from SCCM server. You will also be able to refer to AD for assigning which DPM server.

 The new centralized feature of DPM allows you to manage upto 100 DPM servers from one console while allowing role based administration and centralized reporting from same console. The most cool feature is that you will be able to integrate your DPM server with SCOM 2007R2 and have a scoped view of the issue in DPM console i.e. see only the content in scoped DPM view which is relevant for the alert coming in SCOM [No clutter]. Another interesting features are “Push to resume backups”, integration with service manager and remote console to DPM servers from centralized console. DPM 2012 supports certificates and will introduce block level de duplication. It also now enables Hyper-V item level recovery when DPM is running inside a VM [see the trick for DPM 2010] and uses XML to support applications that do not have a VSS writer and yes you will be able to manage both DPM 2010 and 2012 servers from same centralized console. Last but not the least, I understand DPM 2012 will also support CSV 2.0 i.e. what comes in server V. Next right from beginning.

Yes these features sounds very good and we all are looking forward to DPM 2012. Read more at Mike Resller Blog as it covers a few more features and I hope this was reading pleasure.

Be careful while deploying 2008 R2 SP1 on your Hyper-V R2 clusters

There are some nice fixes in 2008 R2 SP1 and i have seen successful deployment of SP1 on many clusters however I wanted to update you to be careful while deploying SP1 on your hyper-V R2 clusters as there are some reported issues with storage validation after sp1 installation and it seems issue is storage vendor agnostic and Microsoft is already aware and working with those who have reported these issues.
 At same time there are successful deployments of SP1 on hyper-v clusters too so issue may or may not be seen however if you are already seeing the issue, please report here.

Meet me at Tech ED 2011 Bangalore on 23rd March and discuss Failover Clustering

It’s good to be at Microsoft Tech ED and I can vouch that Tech ED is very helpful in getting latest information about new products being launched and to network with fellow MVP’s and Microsoft resources. There are various sessions on different technologies and you get to know the latest from the experts and interact with expert peer community and get lot of opportunities to discuss with peers how they are implementing different solutions and designs and their implementation of technology. Just to give an example I will be interacting with Microsoft DPM product team and get a sneak peek of the new version yet to be launched in Market. In another session, will be meeting the cloud and server division folks to discuss on Remote FX technology which brings value to VDI solution. At the same time MVP community will be accessible if anyone has any specific queries or want to discuss something. You will find me at Bangalore Tech Ed 2011 and feel free to discuss any queries in regards to Hyper-V, failover clustering and System Center technologies. You can find me at “Meet the MVP” session at Tech ED on 23rd March and I will be there to answer your cluster queries and we can have an interesting discussion on failover cluster.

HP 3PAR Geocluster solution for Microsoft Failover Clustering

Somebody asked me month back about HP 3par storage which was acquired by HP last year and there was some competition for this acquisition and question was particularly about the features of 3par storage and advantages around this. Though I am not a storage expert though I am very much impressed by the features of the 3par storage. I thought writing on features of 3par and its advantage in today’s cloud scenario is very relevant. 3par features broadly can be read here

Its architecture and implementation is very different that existing storage technologies. Each physical disk is broken in 256-MB chunklets, each of which can be independently assigned and dynamically reassigned to virtual volumes of different Quality of Service (QoS) levels taking storage from different tiers [golden, silver, bronze]. Host only sees volume at its end irrespective of how that volume has been carved dynamically out of different storage tiers [which could be SSD, FC, SATA]. You can anytime change the storage tiers of your Volume dynamically as per your performance needs. On top of that HP 3par thin technology lets you use thin conversion and persistence technology and not only thin provisioning. You can convert your legacy capacity from full provisioned storage to thin provisioned storage and when data is deleted from the host, volumes are shrinked on the storage [so your storage starts thin and remains thin over the time]. Virtual domain feature enables in delivering secure, segregated access to different user groups which is very essential for a multi tenant cloud infrastructure. It enables Non-disruptive distribution and redistribution of application volumes across storage tiers to align application requirements with data QoS levels on demand and automatically analyzes how volumes use physical disks and makes intelligent, non-disruptive adjustments to ensure optimal volume performance and capacity utilization.

You can also leverage HP 3par Geocluster software for Microsoft windows failover cluster and disaster recovery by automating storage failover between primary and backup sites. In addition, GeoCluster Software support for Microsoft Hyper-V Live Migration increases flexibility through enabling non-disruptive migration of virtual servers. Read more about it here and I hope you will find 3par very attractive option for your cloud designs.

VCenter XVP Manager and Converter enables to manage Hyper-V Infrastructure from within Vsphere Vcenter

VMware has brought a major change it its paradigm and now came with a tool from VMware labs [ Though yet not supported but more of a test, experiment tool ] which will enable customers to manage their Hyper-V environments from within Vsphere Vcenter. VMware vCenter XVP Manager and Converter provides basic virtualization management capabilities for Microsoft Hyper-V platforms towards enabling centralized visibility and control across heterogeneous virtual infrastructures. It also simplifies and enables easy migrations of virtual machines from Hyper-V platform to VMware vSphere and provides familiar vCenter Server graphical user interface for navigating through and managing Hyper-V inventory and is compatible with VMware vCenter Server 4.0 & 4.1 while being scalable to 50 Hyper-V hosts. As of now this tool does not work for Xen hypervisor or any other hypervisor except Microsoft Hyper-V. This very move confirms that VMware is acknowledging Hyper-V as competition and taking it more seriously.
