Eweek: Live Migration Coming into Play in System Refreshes

http://blogs.eweek.com/storage_station/content/general/live_migration_coming_into_play_in_system_refreshes.html Storage virtualization provider DataCore Software is now deploying its SANmelody system in conjunction with the second release of Microsoft Windows Server 2008, working in clustered Hyper-V systems.

The news here is that a Windows Server 2008 R2 Hyper-V cluster now has the ability to "live-migrate" the virtual machines, meaning two cluster nodes have read/write access to the disk at the same time. This wasn't possible in the first release.

The time and money savings of this feature are potentially significant. Live migration elicited a lot of interest recently when DataCore showcased its storage virtualization software at Microsoft's TechEd Europe show in Berlin.

"What this DataCore-Hyper-V setup does is to minimize or even eliminate downtime, when we need to make system changes," said Jack Weisberg, IT director of an early adopter, the New York law firm of McNamee, Lochner, Titus & Williams. "So far this system is working very nicely. Plus, everything is redundant. We have redundant storage with DataCore. And we have redundancy built into the VM system."

When making the purchasing decision to replace some legacy hardware and software, Weisberg said it boiled down to DataCore's SANmelody versus an HP/LeftHand Networks system.
"In comparing both systems, we found both to be strong in terms of their capability of avoiding single points of failure," Weisberg said. "But I really like not being tied to specific hardware -- something DataCore enables. It was very important for us not to get locked into older platforms, when there is newer hardware available on the market that we could use with SANmelody."Using DataCore, the storage solution provider, P&J Computers, was able to use its preferred hardware of choice -- in this case, enterprise-class 6GB SAS drives. DataCore enabled administrators to add a couple of 10GB NICs (network interface cards) in these servers at a very low cost.

So, there's some real-world decision making at work. Is that something you're looking at for 2010?

DataCore Storage Virtualization Software Proves to Be a Great Fit for Microsoft Hyper-V and Cluster Deployments

Case in Point - Law Firm McNamee, Lochner, Titus & Williams

DataCore Storage Virtualization Software Proves to Be a Great Fit for Microsoft Hyper-V and Cluster Deployments; Case in Point - Law Firm McNamee, Lochner, Titus & Williams
Microsoft Hyper-V and DataCore Software's Storage Virtualization Are Winning New Customers Together by Successfully Powering Virtual Infrastructures


DataCore Software announced its SANmelody storage virtualization solution has been deployed along with Microsoft® Windows Server® 2008 Hyper-V™ at the law firm McNamee, Lochner, Titus & Williams. "McNamee/Lochner" is one of the largest law firms in Albany, New York. "The combination of DataCore with Microsoft Windows Server 2008 for Hyper-V allowed us a lot of flexibility to deploy the best solution possible at McNamee/Lochner with the available hardware," stated Kelly M. Knowles, Network Engineer, P&J Computers, Inc.

Hardware Independence - Optimized by Virtualization

McNamee/Lochner had reached a point where the firm needed to increase its storage capacity. "Our storage was growing at a much faster rate than it had in the past," noted Jack Weisberg, IT director, McNamee, Lochner, Titus and Williams. "Moreover, the hardware that we were running on was out of warranty - so we were looking to get something new." Since 2004, the firm had been using a clustered SAN - an HP MSA 1000. Initially, a key requirement in a new system was something that had a solid approach to redundancy, as well as one that offered ease of expansion.
Whereas LeftHand Networks was an early front-runner, since it seemed a logical replacement to the MSA SAN, P&J Computers presented DataCore SANmelody to the firm as well. "In comparing both systems, we found both to be strong in terms of their capability of avoiding single points of failure," noted Weisberg. "But I really like not being tied to specific hardware - something DataCore enables. It was very important for us not to get locked into older platforms, when there is newer hardware available on the market that we could use with DataCore SANmelody."


With DataCore, P&J was able to their preferred hardware of choice - in this case enterprise-class disks 6 GB SAS drives. Knowles praised the ability of DataCore to enable administrators to add a couple of 10 GB NICs in these servers for a very low cost as "tremendous."

P&J Computers - Trusted Solution Providers
DataCore partner P&J Computers, Inc., a data storage and IT service provider, sees the DataCore and Microsoft Hyper-V combination to be not only a good fit - but a great opportunity for both resellers and users alike. It also showcases P&J Computers' ability to be one of the first to implement the latest Windows Server 2008 R2 technology, which was released to the manufacturer (RTM) in July and was just released publicly in October 2009.

P&J Computers is engaged in several accounts where they are deploying DataCore storage virtualization, Windows Server 2008 and Hyper-V in joint configurations. What the partner saw in the new R2 release of Windows Server 2008 release was an opportunity for McNamee/Lochner to take some of the complexity out of its existing environment. What was imperative to making this possible was the release of Windows Server 2008 R2 and the live migration functionality - which was not in Hyper-V prior to R2.

A Virtual Infrastructure - Combining Servers and Storage to Support Mission-Critical Applications

DataCore SANmelody is now deployed in conjunction with a clustered Hyper-V system. Moreover, with a Windows Server 2008 R2 Hyper-V cluster McNamee/Lochner now has the ability to "live migrate" the virtual machines (VMs). Both cluster nodes have read/write access to the disk, at the same time. Running on this infrastructure, there are four (4) VMs that can "live migrate" between the two hosts. Currently, the second node at McNamee/Lochner is located onsite, albeit in a separate rack. "What this DataCore-Hyper-V set-up does is to minimize or even eliminate downtime, when we need to make system changes," noted Weisberg. "So far this system is working very nicely. Plus, everything is redundant. We have redundant storage with DataCore. And we have redundancy built into the VM system."

The multi-Terabyte data pool at McNamee/Lochner and the system is currently supporting 130 users. A third node - running Microsoft Data Protection Manager - is deployed for back-up. The applications McNamee/Lochner uses run on HP DL 380 G6s (dual processor, quad core with Nahalim). The 24 GB of memory can be expanded to 144 GB, if need be. "All the bread and butter applications for running McNamee/Lochner's business will run on this by year-end," noted Knowles.

The next phase of the migration will entail moving what was clustered on Windows 2003 on the old SAN into the virtual environment as well. Space is allocated and P&J Computers just needs to schedule a date to do the cut-over.

Value Protection That Meets Business Objectives
In embracing a virtualized approach, McNamee/Lochner is looking three or four years down the road. Therefore DataCore's "Carry Forward Value Protection Program" - which translates to "Buy - Upgrade - And only pay the difference" - is for McNamee/Lochner a real insurance policy, whereby they might look at new hardware and still keep the same software. "I love this policy that DataCore offers," commented Weisberg. "I am entitled to upgrade the hardware I use with DataCore storage virtualization software. Rather than be forced to scrap my MSA 1000 SAN when it is at its end-of-life, with DataCore I can just buy new hardware and I can continue to use the software - on any new environment I choose. I really think this is awesome."

"We were looking for something redundant, reliable, flexible and expandable," summarized Weisberg. "The DataCore-Hyper-V combination really fit our needs. I certainly like the virtual environment. I also really like having redundant storage. And having seamless failover was key for us as well."

DataCore Virtual SAN Appliance Software Lets Customers Experience New Migration and Clustering Features in Microsoft Hyper-V without Buying a New SAN

http://www.snseurope.com/snslink/news/news-full.php?id=13508&result=datacore

DataCore Software says that customers who don't have a SAN can now experience new features in Microsoft Hyper-V including live migration, dynamic load balancing and high-availability, simply by downloading DataCore's pre-configured Virtual SAN Appliance (VSA).VSA makes it possible for two physical servers to share disks and that is something of great significance to Hyper-V users – since many Hyper-V capabilities require just that. The DataCore VSA comes in a standard VHD format for Microsoft® Windows Server® 2008 Hyper-V™ and Microsoft Hyper-V.The VSA can be downloaded at http://www.datacore.com/msvsappliance/ .
Fully operational in just a few minutes With DataCore's Virtual SAN Appliance Microsoft Hyper-V users can quickly:

  • Utilize Microsoft virtualization environments with an iSCSI SAN created from their server's internal disks. No need for new hardware!

  • Pool up to 1 Terabyte of disk space "Thin Provision" storage to the virtual machines. See how much capacity it saves!

  • Leverage DataCore's "mega cache" capability – this speeds up performance for Exchange, SQL and others applications using surplus server memory to cache I/Os from the virtual SAN

  • Use Snapshots for Instant Volume Cloning and Fast Disk-to-Disk Backups Create a SAN from their server's internal disks

DataCore™ Virtualizes Storage for Microsoft Hyper-V Users "Why wait until you can roll in a SAN?" said Augie Gonzalez, Director of Product Marketing at DataCore Software. "When DataCore can virtualize the physical storage from internal or direct-attached disks to make it behave as a shared storage pool."

Microsoft and DataCore Software Combine to Address ‘Real-World' Site Recovery

http://www.snseurope.com/snslink/news/news-full.php?id=13495&result=datacore
Market Forces: New Virtualization Drivers; Comprehensive Solutions

Despite the tough economic times, Microsoft has noted recent studies which have reported that over 30% of businesses surveyed this year indicated DR will be their main driver for virtualization. These reports show a continued shift, as IT professionals look at addressing new challenges beyond test/dev and basic server consolidation scenarios in deploying virtualization technologies.Microsoft has clearly recognized the importance of site recovery solutions in terms of addressing real-world user scenarios and the benefit of partnering to provide end-to-end solutions that together overcome the limitations of single-vendor, specific site recovery solutions such as VMware's SRM.

Microsoft and DataCore Software Combine to Address ‘Real-World' Site Recovery
Taking machines from one site and replicating them to another site before a calamity unfolds is not new. But buyer beware. Many other disaster recovery products are limiting in that they assume recovery, from one environment to an identical or very similar environment or they support only a subset of the infrastructure. Often physical servers are not supported or require a separate solution from applications and virtual servers. DataCore ASR enables users to execute site recovery operations in a way that is fundamentally different from existing solutions in the marketplace today by bringing the data center together into a single solution.

"The industry is conditioned to think of DR as a one-to-one proposition. This places unreasonable demands on a single recovery site that mirrors the main site," argues Augie Gonzalez, product marketing director at DataCore Software."But most organizations aren't structured that way. They look more like a hub and spoke, with smaller branches emanating from the central data center. For this reason, DataCore's Advanced Site Recovery distributes the disaster recovery workloads among these smaller entities, allowing each of them to accept a more manageable role in keeping the business going."

Microsoft Tech-Ed Virtualization Pavilion Showcases DataCore’s Advanced Site Recovery Software; New Capabilites for Microsoft Hyper-V

Microsoft Virtualization Pavilion Showcases DataCore’s Advanced Site Recovery Software; Extends Disaster Recovery and Clustering Benefits of Microsoft Hyper-V
http://www.it-director.com/technology/storage/news_release.php?rel=14301

DataCore Software was featured last week within the Microsoft Tech-Ed Virtualization pavilion. DataCore showcased its ground-breaking Advanced Site Recovery (ASR) solution for virtual and physical IT infrastructures. Unlike other site recovery approaches that are limited to a specific vendor's virtual machine recovery, DataCore ASR enables both physical and virtual servers to be protected across multiple sites. The combination of DataCore ASR and Microsoft Hyper-V™/ Microsoft® Windows Server® 2008 R2 Failover and Clustering features enables businesses to embrace "real-world" Distributed Disaster Recovery (D-DR) – allowing organizations to cost-effectively spread disaster recovery (DR) responsibilities across several smaller sites.

DataCore Software Updates Storage Virtualization Free Trial Software; Performance Acceleration, Migration Tools + iSCSI, Fibre Channel, FCoE Support

http://vmblog.com/archive/2009/11/03/datacore-software-updates-storage-virtualization-free-trial-software-includes-performance-acceleration-migration-tools-and-support-for-iscsi-fibre-channel-and-fcoe.aspx
DataCore Software announced that it has updated its Free Trial software, which is architected to optimize and manage users’ storage. This free trial of SANmelody™ iSCSI, Fibre Channel over Ethernet (FCoE), and Fibre Channel SAN evaluation software, comes with performance acceleration, content migration, snapshot and thin provisioning – all included. The evaluation software enables data centers and IT departments to consolidate and maximize their disk capacity utilization. SANmelody simplifies management and leverages existing storage hardware and networking to efficiently serve the storage needs for Windows, Netware, MacOS, UNIX, and Linux systems as well as Microsoft, VMware and Citrix virtual servers and desktops.

The Free Trial software http://www.datacore.com/products/prod_SANmel_trynow_form.asp supports group snapshot and cloning, simple content migration and iSCSI and Fibre Channel as well as FCoE.

FCoE Connectivity - Access Fibre Channel storage pool via the LAN switching infrastructure. Application servers and other storage consumers can now access SANmelody nodes equipped with Fibre Channel SAN connections using their Ethernet Network Interface Cards (NICs). This capability takes advantage of the new Fibre Channel over Ethernet protocol and FCoE-compliant switches.

Group Snapshot and Clone Command - Synchronize online snapshots across inter-dependent volumes. This capability coordinates multiple snapshots to occur at the same time across a group of related volumes. It ensures point-time synchronization of file systems and application data that reside on different disks. Fast and efficient disk-to-disk backups across volumes are greatly simplified – plus it ensures that clones created on new equipment are an exact replica of their predecessor.

Content Migration - Relocate active drives into the virtual storage pool. This feature enables existing drives formatted with NTFS file systems to be incorporated easily into the SANmelody storage pool. These physical drives are first un-mounted from the application servers where they were once active, and then reconnected behind a SANmelody node. The SANmelody node acts as an intermediary between the application server and these drives. To take full advantage of SANmelody advanced virtualization features, their contents may be copied to virtual disks using snapshots. The relocated drives can then be wiped clean and included in the physical storage pool as additional capacity, or they may be decommissioned.

See the following announcement on recent DataCore SANmelody enhancements – link: http://www.datacore.com/pressroom/pr_live.asp?date=10/14/2009

Storage Technology News: DataCore SAN Management - School district maintains uptime

http://searchstorage.techtarget.com/news/article/0,289142,sid5_gci1373639,00.html

The Barren County, Ky., school district discovered it could make good use of management features such as thin provisioning and remote mirroring even if they're not included natively with its storage arrays. As part of a virtualization project, the district installed an Emprise 5000 storage system from Xiotech Corp. and DataCore Software Corp.'s SANmelody software to increase uptime and decrease the impact of maintenance on its users.

Barren County school district includes around 4,600 students and 700 faculty. IT Director Steve Gumm and his team handle a high school, middle school, seven elementary schools, the board office, a day care location and four other buildings...

Gumm revamped his storage setup over the summer after the district virtualized all 30 of its servers with VMware. Gumm thought it would be a good time to modernize his storage network, which consisted of a four-year-old EMC iSCSI SAN. The district first went to its server vendor Dell and took a look at an EqualLogic iSCSI SAN. But Gumm wasn't comfortable with the idea of failing over between EqualLogic controllers in different sites during frequent network upgrades.

...Barren installed two 16 TB Fibre Channel systems in separate buildings and Gumm uses SANmelody to manage them with the uptime he wants.

"With SANmelody, we can thin provision those SANs," he said. "We're not utilizing all the space, and thin provisioning lets us use just what is needed at the time. We also use it for data mirroring between both locations. If we need to do maintenance or I need to re-boot my SAN for whatever reason, we drop the SAN here, failover, do our maintenance, failback, and we're up and going."...

"We can manage whatever maintenance needs to be done, whenever we need it," Gumm says of his new setup. "The biggest benefit coming down the road is we're not going to have to do forklift upgrades. When it comes time to add storage, we won't have to rip out the unit. We can add to the unit and allow DataCore to manage where we move data to."

DataCore Releases SANmelody 3.0 - Non-disruptive disk, array, or vendor substitution - Raw Disk Mirroring

DataCore Releases SANmelody 3.0
Latest update version of vendor’s data storage and disk space management platform targets small and midsized businesses
http://www.information-management.com/news/san_storage_area_network_virtualization-10016293-1.html

Non-disruptive disk, array, or vendor substitution - Raw Disk Mirroring
http://sanmelody.blogspot.com/2009/10/raw-disk-mirroring-non-disruptive-disk.html With the release of SANmelody 3.0 PSP2 comes the addition of "raw disk mirroring" which I have touched on in the previous post.
I really don't think this new capability has been given enough coverage when you look at the flexibility it provides. The ability to replace "backend" raw disks without interfering with Virtual Volumes, NMV Volumes or the NMV Pool itself, all while I/O operations continue as normal is an incredible capability.Let look at a scenario: Client maintains a large VMware environment serving ~10TB of data across ~40 thin provisioned virtual volumes server from a SANmelody HA environment with "Vendor A" storage at the backend consisting of many 2Gb FC 146GB 7.5K drives... They are replicating this data to a DR site consisting of SANmelody with "vendor C" disk.Customer has decided to de-comission "vendor A" storage, in place of "vendor B" which contains new 4Gb 300GB 15K rpm drives.Solution: Utilising raw disk mirroring we are able to serve up new capacity from "vendor B" and mirror the raw disks with "vendor A" without touching any of our provisioned volumes. Once mirrors are established we can disconnect "vendor A" and continue as normal without any interuption to the business or to our DR replication solution. But I don't run SANmelody or SANsymphony?.. The 2nd piece of this puzzle is "Proxy volumes support". If you have existing vendor storage and would like the type of flexibility discussed above to migrate data, it can be done. DataCore can "pass through" all of your existing served volumes (with file systems) and mirror the data while it is serving I/O..........
