I recently took time out to review the new features of vsphere 5.1 and this is what I found:
1. Larger and more powerful Virtual Machines
Virtual machines can grow two times larger than in any previous release to support even the most advanced applications. Virtual machines can now have up to 64 virtual CPUs (vCPUs) and 1TB of virtual RAM (vRAM). Why would we want that size of VMs. Well I have never seen a virtual machine that will utilise 64 vcpus, but large applications that run in high performance compute grid networks may just have this requirement and it’s another reason why you would use VMware over the other competitors, XenServer, Hyper-V for example, to run your mission critical intensive application on a the vmware hypervisor.
usefulness : 5/10
2. A new virtual machine format
New features in the virtualmachine format (version 9) in vSphere 5.1 include support for larger virtual machines, CPU performance counters and virtual shared graphics acceleration designed for enhanced performance.
This goes hand in hand with the first feature but notice we have a nice shared graphics acceleration feature. NVIDIA added vSGA (Virtual Shared Graphics Acceleration) that allows the presentation of a physical graphics processing unit (GPU) from the underlying host to virtual desktops guests. By virtualizing the physical GPU, its resources can be allocated and shared across several virtual desktop instances. This provides several different benefits. Using the physical GPU and vRAM frees the underlying CPU and memory from the host to be used for other tasks. Using a GPU for hardware-accelerated graphics also allows customers to provide a more rich and interactive graphical experience across an even broader set of use cases, especially implementation of vmware view.
3. Storage enhancements
Flexible, space-efficient storage for virtual desktop infrastructure (VDI). A new disk format enables the correct balance between space efficiency and I/O throughput for the virtual desktop.
4. vSphere Distributed Switch enhancements
Enhancements such as NetworkHealth Check, Configuration Backup and Restore, Roll Back andRecovery, and Link Aggregation Control Protocol support anddeliver more enterprise-class networking functionality and a more robust foundation for cloud computing.
Anything distributed switch is good and useful – it is a great part of the product and really helps define network policies more efficiently, especially when you have large numbers of hosts.
5. Single-root I/O virtualization (SR-IOV) support
Support forSR-IOV optimizes performance for sophisticated applications. SR-IOV is a specification that allows a PCIe device to appear to be multiple separate physical PCIe devices. Here is a great video explain SR-IOV and how resources are assigned to each particular function. This all helps with over performance and with point 1 and larger machines, all feeds back in to the fact that VMware ESX can handle bigger workloads
6. AvailabilityvSphere vMotion enhancements
Leverage the advantages of vMotion(zero-downtime migration) without the need for shared storage configurations. This new vMotion capability appliesto the entire network. This is great – This means you can migrate virtual machines live without needing “shared storage”. In other words you can vMotion virtual machines between ESXi hosts with only local storage
7. vSphere Data Protection changes
Simple and cost effective backupand recovery for virtual machines. vSphere Data Protection isa newly architected solution based on EMC Avamar technology that allows admins to back up virtual machine data to diskwithout the need of agents and with built-in deduplication. This feature replaces the vSphere Data Recovery product available with previous releases of vSphere.
A great white paper from VMware regarding this: http://www.vmware.com/files/pdf/techpaper/Introduction-to-Data-Protection.pdf
8. vSphere Replication
vSphere Replication enables efficientarray-agnostic replication of virtual machine data over the LAN or WAN. vSphere Replication simplifies management enablingreplication at the virtual machine level and enables RPOs as low as 15 minutes.
I like this one. Again another feature rich offering from Vmware.
9. Reduced downtime upgrade for VMware Tools
After you upgrade to the VMware Tools available with version 5.1, reboots have been reduced or eliminated for subsequent VMware Tools upgrades on Windows.
Been a while coming due to the challenges of upgrading locked files within an operating system most probably not the best and easiest to work within when you are VMware. We here and expect some more enhancements coming in the later versions.
10. Additional security enhancements
VMware vShield Endpoint delivers a proven endpointsecurity solution to any workload with an approach that is simplified, efficient, and cloud-aware. vShield Endpoint enables3rd party endpoint security solutions to eliminate the agentfootprint from the virtual machines, offload intelligence to a security virtual appliance, and run scans with minimal impact.
This was once bluelane and its now bundled in the product. It makes a lot of sense when you are running multiple instances of security as you can now limit the overhead.
11. vSphere Storage DRS and Profile-Driven Storage
New integration with VMware vCloud® Director™ enables further storage efficiencies and automation in a private cloud environment. This is cool – a feature that allows us to DRS storage IO. Not tested in anger but a great performance tool in an already feature rich product.
12. vSphere Auto Deploy
Two new methods for deployingnew vSphere hosts to an environment make the Auto Deploy process more highly available then ever before. This is my favourite. Stateless and stateful ESXi deployments. Got to be worth a bucket of comfort knowing that whatever happens, the ESXi host will also boot up.
13. VMware vCenter™ Operations Manager Foundation
This enables you to leverage comprehensive views into health, risk and efficiency scores of your vSphere environment infrastructure. Quickly drill down to see what’s causing current workloadconditions, pinpoint potential problems in the future andidentify areas with inefficient use of resources.
14. vCenter Orchestrator
Orchestrator simplifies installation and configuration of the powerful workflow engine in vCenter Server. Newly designed workflows enhance ease of use, and canalso be launched directly from the new vSphere Web Client. vCO is a powerful tool and one that you can do truck loads with – alot of large service providers would use this to prep a machine when it is being provisioned, for example, creating a naming convention, putting this VM in the right container within a management domain, installing management tools . Always a good thing
15. Management using vSphere Web Client
The vSphere Web Client is now the core administrative interface for vSphere. This new flexible, robust interface simplifies vSphere control through shortcut navigation, custom tagging, enhanced scalability, and the ability to manage from anywhere with Internet Explorer orFirefox-enabled devices.
This is a big winner for me. Still we need a windows installer and an operating system to run on but its a big move in the right direction.
16. vCenter Single Sign-On
vCenter SSO is sometimes misunderstood and this is a great step in the right direction. SSO will act as a proxy rather than a authenticator and what I mean by this is that you can now have mulitple directory services configured to authenticate your user on to a vCenter environment. There is a great blog from Arnim Van Lieshout which describes this in more detail – http://www.van-lieshout.com/2013/08/vcenter-single-sign-on-sso-is-an-authentication-proxy/
VMware are still ahead of the game. XenServer is catching up and have a release later on in the year called the Augusta release which has features like dom0 disaggregation and Hyper-V 2012 has all the features now, but as VMware still have a huge foot in the industry, they need to now move up the stack and take more advantage of workflows and the automation features that are possible,
well its a 9/10 for me. Keep up the good work VMware, you really are some software provider who have changed the face of infrastructure.
