Editor's Notes
- But how does it work?Offloaded Data Transfer (ODX) support is a feature of the storage stack of HyperāV in Windows Server 2012. ODX, when used with offload-capable SAN storage hardware, lets a storage device perform a file copy operation without the main processor of the HyperāV host actually reading the content from one storage place and writing it to another.ODX uses a token-based mechanism for reading and writing data within or between intelligent storage arrays. Instead of routing the data through the host, a small token is copied between the source and destination. The token simply serves as a point-in-time representation of the data. As an example, when you copy a file or migrate a virtual machine between storage locations (either within or between storage arrays), a token that represents the virtual machine file is copied, which removes the need to copy the underlying data through the servers. In a token-based copy operation, the steps are as follows:<Click>A user initiates a file copy or move in Windows Explorer, a command-line interface, or a virtual machine migration.<Click>Windows Server automatically translates this transfer request into an ODX (if supported by the storage array) and receives a token representation of the data.<Click>The token is copied between the source and destination systems.<Click>The token is delivered to the storage array.<Click>The storage array performs the copy internally and returns progress status.ODX is especially significant in the cloud space when you must provision new virtual machines from virtual machine template libraries or when virtual hard disk operations are triggered and require large blocks of data to be copied, as in virtual hard disk merges, storage migration, and live migration. These copy operations are then handled by the storage device that must be able to perform offloads (such as an offload-capable iSCSI, Fibre Channel SAN, or a file server based in Windows Server 2012) and frees up the HyperāV host processors to carry more virtual machine workloads.As you can imagine having an ODX compliant array provides a wide range of benefits:ODX frees up the main processor to handle virtual machine workloads and lets you achieve native-like performance when your virtual machines read from and write to storage.ODX greatly reduces time to copy large amounts of data.With ODX, copy operations donāt use processor time.Virtualized workload now operates as efficiently as it would in a non-virtualized environment.<next slide>
- As was stated earlier, Dynamic Memory was introduced with Windows Server 2008 R2 SP1 and is used to reallocate memory between virtual machines that are running on a Hyper-V host. Improvements made within Windows Server 2012 Hyper-V includeMinimum memory setting ā being able to set a minimum value for the memory assigned to a virtual machine that is lower than the startup memory settingHyper-V smart paging ā which is paging that is used to enable a virtual machine to reboot while the Hyper-V host is under extreme memory pressureMemory ballooning ā the technique used to reclaim unused memory from a virtual machine to be given to another virtual machine that has memory needsRuntime configuration ā the ability to adjust the minimum memory setting and the maximum memory configuration setting on the fly while the virtual machine is running without requiring a reboot.Because a memory upgrade requires shutting down the virtual machine, a common challenge for administrators is upgrading the maximum amount of memory for a virtual machine as demand increases. For example, consider a virtual machine running SQL Server and configured with a maximum of 8 GB of RAM. Because of an increase in the size of the databases, the virtual machine now requires more memory. In Windows Server 2008 R2 with SP1, you must shut down the virtual machine to perform the upgrade, which requires planning for downtime and decreasing business productivity. With Windows Server 2012, you can apply that change while the virtual machine is running.[Click]As memory pressure on the virtual machine increases, an administrator can change the maximum memory value of the virtual machine, while it is running and without any downtime to the VM. Then, the Hot-Add memory process of the VM will ask for more memory and that memory is now available for the virtual machine to use.<next slide>
- Your computing resources are limited. You need to know how different workloads draw upon these resourcesāeven when they are virtualized. In Windows Server 2012, HyperāV introduces Resource Metering, a technology that helps you track historical data of the use of virtual machines. With Resource Metering, you can gain insight into the resource use of specific servers. You can use this data to perform capacity planning, to monitor consumption by different business units or customers, or to capture data needed to help redistribute the costs of running a workload. You could also use the information that this feature provides to help build a billing solution, so that customers of your hosting services can be charged appropriately for resource usage.HyperāV in Windows Server 2012 lets providers build a multitenant environment, in which virtual machines can be served to multiple clients in a more isolated and secure way, as shown in the figure. Because a single client may have many virtual machines, aggregation of resource usage data can be a challenging task. However, Windows Server 2012 simplifies this task by using resource pools, a feature available in HyperāV. Resource pools are logical containers that collect resources of the virtual machines that belong to one client, permitting single-point querying of the clientās overall resource use.HyperāV Resource Metering has the following features:Uses resource pools, logical containers that collect resources of the virtual machines that belong to one client and allow single-point querying of the clientās overall resource use.Works with all HyperāV operations. Helps ensure that movement of virtual machines between HyperāV hosts (such as through live, offline, or storage migration) doesnāt affect the collected data.Uses Network Metering Port ACLs to differentiate between Internet and intranet traffic, so providers can measure incoming and outgoing network traffic for a given IP address range.Resource Metering can measure the following:Average CPU use. Average CPU, in megahertz, used by a virtual machine over a period of time.Average memory use. Average physical memory, in megabytes, used by a virtual machine over a period of time.Minimum memory use. Lowest amount of physical memory, in megabytes, assigned to a virtual machine over a period of time.Maximum memory use. Highest amount of physical memory, in megabytes, assigned to a virtual machine over a period of time. Maximum disk allocation. Highest amount of disk space capacity, in megabytes, allocated to a virtual machine over a period of time.Incoming network traffic. Total incoming network traffic, in megabytes, for a virtual network adapter over a period of time. Outgoing network traffic. Total outgoing network traffic, in megabytes, for a virtual network adapter over a period of time. <next slide>
- NOTE: This slide is animated and has 4 clicksWith Windows Server 2012 Hyper-V, you can also perform a āShared Nothingā Live Migration where you can move a virtual machine, live, from one physical system to another even if they donāt have connectivity to the same shared storage. This is useful, for example, in a branch office where you may be storing the virtual machines on local disk, and you want to move a VM from one node to another. This is also especially useful when you have two independent clusters and you want to move a virtual machine, live, between them, without having to expose their shared storage to one another. You can also use āShared Nothingā Live Migration to migrate a virtual machine from one datacenter to another provided your bandwidth is large enough to transfer all of the data between the datacenters.As you can see in the animation, when you perform a live migration of a virtual machine between two computers that do not share an infrastructure, Hyper-V first performs a partial migration of the virtual machineās storage by creating a virtual machine on the remote system and creating the virtual hard disk on the target storage device.[Click]While reads and writes occur on the source virtual hard disk, the disk contents are copied over the network to the new destination virtual hard disk.This copy is performed by transferring the contents of the VHD between the two servers over the IP connection between the Hyper-V hosts.[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.This copy is performed by transferring the contents of the VHD between the two servers over the IP connection between the Hyper-V hosts.[Click]After the source and destination virtual hard disks are synchronized, the virtual machine live migration process is initiated, following the same process that was used for live migration with shared storage.After the virtual machineās storage is migrated, the virtual machine migrates while it continues to run and provide network services. [Click]After the live migration is complete and the virtual machine is successfully running on the destination server, the files on the source server are deleted.
- Lets consider a simplistic scenario:You have a client and server. You want to request data of say 500k from the client ā this typically goes through the TCP/IP stack, you place a request for getting the data to the server, the data gets read, gets broken down into smaller packets, transferred back to you. You assimilate all these packets into the 500k data that you asked for and send it back up. All this takes CPU resources. You cant send the entire 500k at once no matter how fast your NIC is. You still have to chop it down into small packets and send it up and down the stack. Now think about having multiple NICs doing a lot of IO intensive operations. Your CPU is just busy doing this over and over again. You donāt want your CPU to be used for this ā you want it to work on servicing database requests, indexing and so on. We worked with a lot of network adapter vendors to bring a class of specialized NICs to support high speed data transfers with SMB Direct into Windows Server 2012. These NICs have a better CPU in them and support Remote Direct Memory Access or RDMA so that they can transfer data between them without involving the host CPU. How does it work ā I need to read 500k of data. First I find out a place in memory where that data should reside, then I register that with the NIC and get a token back. I send this token back to the other side through SMB direct and say I need to read 500k of data. Now the host uses this token, identifies the memory that needs to be copied, passes the memory location and the token to the NIC and says this is the data that needs to be transferred, why donāt you guys just talk with each other and transfer the data over. So the two NICs actually do the transfer. The two CPUs are now busy doing something else. RDMA can be incredibly fast ā 1-2 ms latency when doing transfers. We support Infiniband, RoCE and iWARP network interfaces.New in Windows Server 2012 R2, we are taking advantage of RDMA technology and are introducing it to Hyper-V live migrations taking advantage of the SMB protocol. As in the case with regular SMB file transfers, RDMA enables the offloading of CPU resources to NICs during live migration. This means that live migrations can now take advantage of high-speed networking, and they can also stream over multiple networks for improved bandwidth. Live migration with RDMA delivers the highest performance for live migrations, supporting transfer speeds of up to 56 GB/s.
- Enterprise class performance and scale have traditionally been associated with high-end storage solutions. But not everyone can afford an expensive SAN ā most customers are looking at options that gives them the same kind of reliability, resiliency and availability that high-end solutions offers but at the cost of industry-standard hardware. With WS 2012, we donāt have any 2nd class citizens ā no matter what storage solution you have, we help you make the most out of your investment and use your resources efficiently. A fundamental assumption we made when we built the product was that underlying hardware can fail or be unreliable due to several reasons ā planned or unplanned and the services that run on top should be as transparent to these failures as possible. With that in mind, lets look at some of the features we have added in WS 2012
- We have had virtualization at Hyper-V layer over the last couple of releases of Windows server. With Windows Server 2012, we give you the ability to virtualize your storage solution. Storage spaces gives you the ability to consolidate all your SAS and SATA connected disks ā no matter whether they are SSDs or traditional HDDs and consolidate them together as storage Pools. <Click>You can then assign these pools to different departments within your enterprise or customers so that your data is isolated and administration is easy. Once you have created these pools, you can then create logical disks from them, called Storage Space. <Click>These logical disks, for the most part looks and acts like regular disks. But they can be configured for different resiliency schemes ā mirroring or parity depending the performance and space requirements.When you create a Storage space, you can either choose thin or fixed provisioning. This lets you have the ability to increase your storage investments only when you need. You can create a logical disk or Space that is bigger than your pool and add disks only when there is an actual need.<Click>Lets assume that your Hyper-V VMs are stored in logical disks created using Storage Spaces. With trim provisioning, when a large file gets deleted from one of the VMs, the VMs communicate this to the host and the host down to storage spaces and spaces will automatically reclaim this storage and assign it to other disks within the same pool or other pools. So you are optimizing storage utilization with on-demand provisioning and automated capacity reclamation.<Click>Storage Spaces is compatible with other Windows Server 2012 storage features, like SMB Direct and SMB Failover Clustering, so you can use simple inexpensive storage devices to create powerful and resilient storage infrastructures on a limited budget. <Click>Storage Spaces enable you to deliver a new category of highly capable storage solutions to all Windows customer segments at a dramatically lower price point. At the same time, you can maximize your operations by leveraging commodity storage to supply high-performance and feature-rich storage to servers, clusters, and applications alike.
- [CLICK]Hot data is data that changes frequently and is stored on the faster, but more expensive, solid state drives. All data starts as hot data. [CLICK]Cold data is data that changes infrequently and is stored on the slower, but cheaper, hard disk drives. [CLICK] If cold data becomes hot it will be automatically moved to the solid state drives, and if [CLICK] hot data becomes cold it is moved to the hard disk drives.
- Data deduplication is a new storage efficiency feature available with Windows Server 2012 that helps address the ever-growing demand for file storage. Instead of expanding the storage used to host the data, the amount of space used by that data is now reduced through the use of variable-size chunking and compression. What this means is that Windows will automatically scan through your disks, identify duplicate chunks in the data you have stored and store these chunks only once. Since only one copy is stored for duplicate data this not only lets you optimize your existing storage infrastructure, it also translates into even greater savings by postponing the need to purchase storage upgrades and extending the lifespan of current storage investments. The disk space savings we have seen with Data Dedup during testing, both internally and by ESG Lab, has been phenomenal. Data deduplication can deliver storage savings of 25-60% for general file shares and 98% for OS VHDs. This is far above what was possible with Single Instance Storage (SIS) or NTFS compression.Data deduplication also throttles CPU and memory usage to allow for implementation on large volumes without impacting server performance. Furthermore, compression routine run times can be scheduled for off-peak times to reduce any impact those operations might have on data access.Reliability and data integrity arenāt problems for data deduplication, thanks to metadata and preview redundancy that helps to prevent data loss due to unexpected power outages. Checksums, along with data integrity and consistency checks, also help prevent corruption for volumes configured to use data deduplication.Not for :Live VMsSQL DBsReFS file sharesClient machinesBoot dataCluster shared volumes

- With the new release of Windows PowerShell, sessions aren't just persistent; they are resilient. Robust Session Connectivity allows sessions to remain in a connected state even when network connectivity is briefly disrupted.With Robust Session Connectivity, remote sessions can remain in a connected state for up to 4 minutes, even if the client computer crashes or becomes inaccessible, and tasks on the managed nodes continue to run on their own making the end to end system more reliable. If connectivity cannot be restored within 4 minutes, execution on the managed nodes is suspended with no loss of data and remote sessions automatically transition to a disconnected state, allowing them to be reconnected after network connectivity is restored. Corruption of application and system state from premature termination of running tasks due to unexpected client disconnection is virtually eliminated
