  • With Win2012 designed for cloud deployment, we want to have a scenario to support not only FS, but HV, SQL, IIS natively run in Windows environment and at the same time reduce CAPEX and reduce ongoing maintenance cost.There are 3 scenario:As a customer, we want an Enterprise class solution with a lower costWith the cheapest solution, we want to make sure the storage be a able support always on- always up applicationWithout buffer of waiting time, we want a solution that deliver the highest performance, scalability and give us an additional choice in term of storage,
  • Let look into 1st ScenarioThe goal is Enterprise class solution which as the same performance as iSCSI & FCOptimize as much storage as possibleNo matter what happen, the system must up and runningLowest cost
  • Hyper-V as the virtualization platform.Next, we are now introducing Storage virtualization (aka Storage Spaces) which give you ability to virtualize storage solution.This option allow us to combine a bunch of disk , just standard disk (cheap disk) and use the functionality of Win2012 to consolidate them together as storage pool.Storage Pool -> Virtual Disk (Logical disk)VD -> RAID 0, RAID1, & RAID 5 to offer various level of performance and data protection as neededThin provisioning / Fixed Provisioning.Storage Spaces compatible with Win2012 features. This can turn inexpensive storage into enterprise class storage which allow you to run FS, Hyper-V & SQL Server
  • Windows Server 2012 now offers support for application-based file shares. SMB 3.0 support running Hyper-V & SQL Server.Previous we have iSCSI & FC to store HA VM & SQL DB.For HA, we will configure as cluster and store VM & SQL DB. With SMB 3.0, you will have a features called SMB direct & SMB Multichannel which I’m going to cover later.
  • Let look into data dedup. It is a feature which available in file shares. It eliminate your redundant data & fully optimize your storage.Example:- 10TB of file shareBenefit of having dedup:-Space OptimizationReduce your backup data & save your WAN bandwidth.
  • Storage that can stand forH/w FailureLow cost Cater for patch Tuesday that cost server downtimeContinues availability on Hyper-V, storage & network
  • Previously we have NTFS file format. Now we have Resilient File System (ReFS) .Key goad:_Compatibility with NTFSMaintain high level of system availability & reliabilityMore resilient especially during power outageCheckdisk improvementTake sec to fix corrupted dataNo more offline disk when perform checking
  • As I just mentioned, you can use Hyper-V over SMB & SQL over SMB. With SMB transparent failover, there is no loss connection especially when perform planned / unplanned failover.You will not reliase any downtime.
  • Now let look into how we cater for patch Tuesday.
  • With Win2012 we can now configure block level storage. You can setup iSCSI Target. In the past, we need to download separate component. But now iSCSI is ship in the box. To ensure HA, we can configure clustering.Talking about NFS- We can setup and deploy cluster NFS to ensure continuos high availability to use by Vmware.
  • NOTE: This slide is animated and has 3 clicksNot only can we live migrate a virtual machine between two physical hosts, Hyper‑V in Windows Server 2012 introduces live storage migration, which lets you move virtual hard disks that are attached to a running virtual machine without downtime. Through this feature, you can transfer virtual hard disks, with no downtime, to a new location for upgrading or migrating storage, performing backend storage maintenance, or redistributing your storage load. You can perform this operation by using a new wizard in Hyper‑V Manager or the new Hyper‑V cmdlets for Windows PowerShell. Live storage migration is available for both storage area network (SAN)-based and file-based storage.When you move a running virtual machine’s virtual hard disks, Hyper‑V performs the following steps to move storage:Throughout most of the move operation, disk reads and writes go to the source virtual hard disk.[Click]After live storage migration is initiated, a new virtual hard disk is created on the target storage device. While reads and writes occur on the source virtual hard disk, the disk contents are copied to the new destination virtual hard disk.[Click]After the initial disk copy is complete, disk writes are mirrored to both the source and destination virtual hard disks while outstanding disk changes are replicated.[Click]After the source and destination virtual hard disks are synchronized, the virtual machine switches over to using the destination virtual hard disk.The source virtual hard disk is deleted.Just as virtual machines might need to be dynamically moved in a cloud data center, allocated storage for running virtual hard disks might sometimes need to be moved for storage load distribution, storage device servicing, or other reasons.[Additional information]Updating the physical storage that is available to Hyper‑V is the most common reason for moving a virtual machine’s storage. You also may want to move virtual machine storage between physical storage devices, at runtime, to take advantage of new, lower-cost storage that is supported in this version of Hyper‑V, such as SMB-based storage, or to respond to reduced performance that can result from bottlenecks in the storage throughput. Windows Server 2012 provides the flexibility to move virtual hard disks both on shared storage subsystems and on non-shared storage as long as a Windows Server 2012 SMB3 network shared folder is visible to both Hyper‑V hosts.You can add physical storage to either a stand-alone system or to a Hyper‑V cluster and then move the virtual machine’s virtual hard disks to the new physical storage while the virtual machines continue to run.Storage migration, combined with live migration, also lets you move a virtual machine between hosts on different servers that are not using the same storage. For example, if two Hyper‑V servers are each configured to use different storage devices and a virtual machine must be migrated between these two servers, you can use storage migration to a shared folder on a file server that is accessible to both servers and then migrate the virtual machine between the servers (because they both have access to that share). Following the live migration, you can use another storage migration to move the virtual hard disk to the storage that is allocated for the target server.You can easily perform the live storage migration using a wizard in Hyper‑V Manager or Hyper‑V cmdlets for Windows PowerShell.BenefitsHyper‑V in Windows Server 2012 lets you manage the storage of your cloud environment with greater flexibility and control while you avoid disruption of user productivity. Storage migration with Hyper‑V in Windows Server 2012 gives you the flexibility to perform maintenance on storage subsystems, upgrade storage appliance firmware and software, and balance loads as capacity is used without shutting down virtual machines.Requirements for live storage migrationWindows Server 2012.The Hyper‑V role.Virtual machines configured to use virtual hard disks for storage.
  • ODX (offload and get the best out of the array) - You can do copy and moving of data within an array.Let say, you a have large file, you can leverage ODX capable to faster transfer file within an array without using network & reduce CPU resource utilization.
  • SMB Direct. Without attach FC attached storage, we can also achieve high performance storage.Example:- FS Client & FS ServerIt will go through different layer and Data break into smaller packet and transfer between S & C. All this consume a lot of CPU utilization.To solve this problem, with RDMA compliant network adapter, we can bypass network layer & give full performance capacity. It will bypass CPU & give it to do other thing.RDMA compatibility is currently limited to InfiniBand, iWARP, and RoCE (RDMA over Converged Ethernet)RDMA wont work in Win 2012 NIC Teaming. But MPIO and SMB Multi Channel are preferred.
  • For those who do not want to hassle to setup SMB as storage. We also have Windows Cluster in a box. It is just a box. Low cost solutionAll you do is plug the box with power.It is suitable for branch / medium business. 2 option:- one with Storage Space / Cluster RAID controller.It is JBOD enclosure.
  • The next topic is Windows Storage Server 2012. It is ship with full blown of Win 2012 and do not need to configure a lot of setting.In the past we have 4 edition, now we reduce to 2. Here is a table of the comparison of two versionEntry level – WorkgrouoStandard – for HAFor Hyper-V use, Deducp, Branch cache, it is recommend to get Standard Edition.
