just another cloudy day….

VMware hits out at Microsoft…. AGAIN !!

NOTE from yoyoclouds: Although I must admit I am a HUGE fan of VMware… but I hold no grudges what so ever against Microsoft… This was taken from a Blog posted on VMware’s Community Site..!!

Sorry Microsoft; Not Only Does vSphere Cost Less to Buy, It Also Costs Less to Operate

Microsoft’s wildly exaggerated claims of providing a less expensive virtualization platform than VMware vSphere have been hard to miss if you’ve spent any time on the web lately. We’ve previously pointed out the flaws in their math and our public Cost Per Application Calculator clearly shows how deploying a virtual infrastructure built with vSphere will cost about the same as one built using Microsoft Hyper-V and System Center (or even much less when vSphere’s proven VM density advantage over Hyper-V is factored in.) Now we’re pleased to share recent independent test results that show how vSphere also delivers dramatically lower operational costs compared to Microsoft.

The acquisition capital expense (CapEx) advantage for vSphere shown by our Cost Per Application Calculator is just part of the Total Cost of Ownership (TCO) that diligent customers will want to evaluate when choosing a virtualization and cloud platform. The other key TCO element to consider is Operational Expenses (OpEx) representing the ongoing costs of administering your virtual infrastructure. To help customers assess the OpEx differences between vSphere and Hyper-V, we enlisted Principled Technologies to run both platforms in their labs and measure the system administrator labor time needed for typical recurring tasks.
Five Typical Datacenter Tasks Tested

Principled Technologies selected five common tasks that any administrator of a virtualized datacenter must regularly perform and they measured the administrator labor time taken to complete each one using both the VMware and Microsoft platforms. The tasks tested were:

  • Shifting virtual machines off a host to accommodate physical maintenance
  • Adding storage volumes and redistributing virtual disk files across the new storage
  • Isolating storage-intensive “noisy neighbor” virtual machines
  • Provisioning new hosts
  • Performing a non-disruptive disaster recovery failover test

Care was taken to conduct the scenario tasks as realistically as possible using the full capabilities of the latest released versions of the VMware and Microsoft products available at the time of the testing. vCenter Site Recovery Manager was included in the VMware configuration (and the full list SRM license costs were included in the VMware total cost figures.) vSphere 5 delivered a convincing across-the-board win over Microsoft for each task tested: tasks took 78% to 97% less time to complete using vSphere. The time savings provided by the VMware platform arise from the more advanced capabilities built into vSphere and the more efficient and optimized implementation of those features we’ve perfected over our years of focusing purely on delivering the best virtual infrastructure and cloud platform.

It’s important to note that the OpEx dollar savings shown in the chart above derive from only five representative sysadmin tasks. There are many other regular activities performed by administrators of virtualized datacenters, most of which will show similar efficiency advantages for vSphere over less mature and capable alternatives, so customers should expect even greater total OpEx savings from using vSphere.
Scenarios Delivering Big OpEx Wins for vSphere

Contributors to the biggest operational advantages for vSphere were:

  • Storage Distributed Resource Scheduler – When more storage is needed, the vSphere administrator can add volumes and let Storage DRS redistribute virtual disk files to the new volumes automatically with no VM downtime. The Hyper-V administrator must manually redistribute VM storage and make arrangements for VM downtime during the operation.
  • Concurrent vMotion – The vSphere administrator can complete physical host maintenance much sooner because vMotion maintenance mode evacuations of VMs can proceed concurrently and at a faster rate (see comparative live migration testing results here.) Hyper-V hosts can only handle one live migration at a time, so administrators are tied up with much longer maintenance windows.
  • Storage I/O Control – vSphere makes it easy to cap the storage IOPS consumed by each VM to prevent resource hogging by “noisy neighbors.” Hyper-V has no such feature, so administrators can only respond by dedicating storage volumes for misbehaving VMs – a tedious task requiring VM downtime.
  • vCenter Site Recovery Manager – SRM fully automates replication of mission-critical VMs to a remote site and failover in case of disaster. Real disasters may be rare, but full-scale DR tests should be regular events. That’s where the automated and non-disruptive DR failover test features in SRM deliver big operational savings. Setting up DR failovers with Hyper-V requires maintenance-intensive scripting to orchestrate VM replications and restarts and to modify VMs for network isolation.

After making their labor time measurements, Principled Technologies then estimated how many times each task would be repeated over the course of a two-year period in a datacenter operating 1,000 virtual machines. Multiplying the cumulative time taken performing each task by the U.S. national average system administrator compensation rate gave a dollar figure for the OpEx savings. As shown below, the final result was an impressive 91% reduction in operational expenses when using vSphere compared to Microsoft Hyper-V and System Center.

Operational Expenses Dominate Total Costs

The impact of the OpEx savings delivered by vSphere are even more significant when you consider that IT operational expenses are typically much larger than capital expenses. In fact, Gartner survey data shows cross-industry IT OpEx spending is almost three times CapEx spending – even more reason to choose a virtualization platform that will save you money with better operational efficiency long after the initial purchase.

The OpEx savings delivered by vSphere were enough to tip the two-year TCO advantage in favor of VMware in the 1,000-VM datacenter that was the baseline for Principled Technologies’ tests. When you can have the clearly superior features provided by vSphere 5 Enterprise Plus Edition together with vCenter Site Recovery Manager at a lower total cost than Microsoft’s best alternative, it’s easy to make the decision to go with VMware.

If you’re running your datacenter on vSphere now, an OpEx win by vSphere probably isn’t surprising. vSphere users benefit from over a decade of optimizations we’ve built into our platform that derive from experience in thousands of production datacenters. What did surprise us was just how large an operational advantage vSphere has over the Microsoft platform. The results are a clear example of why you need to look at more than just a feature checklist and initial price tag when choosing the virtualization platform for your most critical workloads.

Whats new in VMware vSphere 5?

vSphere 5 New Features

As with any major upgrade, improvements to speed, stability and scalability are some of the important “new” features.  Virtual machines can be larger in vSphere 5. Virtual machines with up to one terabyte of memory and up to 32 CPUs are now supported. VMware says that vSphere 5 VMs can handle over one million IOPS. vSphere 5 is also the first version of vSphere to be developed completely on ESXi which is independent from any other operating system. ESXi’s only purpose is to run VMware which means it has a very thin, optimized footprint of less than 100 MB.

However, vSphere 5 is about more than just bigger and faster.  VMware says there are over 200 new features in the latest edition of vSphere.

vSphere 5 supports three new automated functions that form the backbone of an intelligent policy management system. The idea is that administrators can configure policies that enable a “set it and forget it” approach to managing virtualization in the datacenter.

The first of these new features is Auto-Deploy. Auto-Deploy automatically deploys severs on the fly using a PXE boot to turn on the server, install an image and then add the systems resources into an existing pool. Auto-Deploy allows 40 severs to be deployed in 10 minutes instead of 20 hours. Once the servers are running, the Auto-Deploy policy can also automatically patch the installations.

Profile-Driven Storage groups storage according to user-defined policies. When provisioning resources, administrators select the level of service required and vSphere automatically chooses the available resources that best correspond to the selected level.

Finally, Storage DRS automatically manages the placement and balancing for a VM across storage resources according to the storage policy of the virtual machine, eliminating the need for an administrator to monitor and reallocate resources to maintain the necessary level of service.

 

VMware vSphere Storage Appliance

In an effort to reach the small and medium sized business (SMB) market, VMware also announced the VMware vSphere Storage Appliance.

One of the complexities for SMB enterprises looking to capitalize on the power of VMware server virtualization is the implementation and management of shared storage. The VMware vSphere Storage Appliance seeks to address this concern.  Using the appliance, customers can take advantage of features like High Availability and vMotion without having to implement their own shared storage infrastructure. Instead, the vSphere Storage Appliance integrates with VMware to pool the internal server storage and present it as shared storage to create a virtual pool of storage without the need for external storage. Since the physical storage is spread across numerous physical servers, the storage pool acts and responds in the same manner as an array of external physical storage.

The vSphere Storage Appliance can take full advantage of the new vSphere 5 allowing SMBs without complex shared storage configurations to also benefit from the intelligent policy management that drives the hallmark set it and forget it features of vSphere 5.

Network I/O control, virtual firewall updates


As with storage management, vSphere 5 users will reportedly be able to establish networking resource pools according to pre-defined rules. The new version will also enable multi-tenancy deployment, and will bridge physical and virtual QoS by complying with a new IEEE 802.1 VLAN tagging standard.

New vSphere Pricing Model

With vSphere 5, VMware introduces a new pricing model that is no longer based on the physical server hardware. Instead, vSphere 5 is priced according to the amount of virtual resources allocated. There are now just three pricing tiers, Standard, Enterprise and Enterprise Plus.

The Standard tier allows up to 24 GB of allocated memory to all virtual machines and up to eight virtual CPUs per virtual machine. Enterprise allows 32 GB of virtual memory across all virtual machines and up to eight virtual CPUs per VM. Enterprise Plus allows up to 48 GB across virtual machines and up to 32 virtual CPUs per VM.

The new pricing model hasn’t been warmly received, in part because existing VMware customers purchased hardware to maximize the value under the vSphere 4 licensing model where pricing was based on the number of sockets and cores in the server. In particular, the vSphere 4 Enterprise Plus license allows for unlimited memory. Companies purchased servers with huge amounts of memory tied to just one or two processors with six cores meaning they needed just one or two Enterprise Plus licenses per server.
