What do I think about the stability of the solution?
Due to the multitude of configuration options, you can occasionally experience compatibility issues with 3rd party storage vendors such as NetApp which recently had a known issue with NFS reporting all ports down.
What do I think about the scalability of the solution?
Never encountered any scalability issues with this product. It is truly enterprise.
How are customer service and support?
Customer Service: Good to excellent.Technical Support: Good to Excellent depending on what engineer is assigned to you.
Which solution did I use previously and why did I switch?
I have tried other hypervisor technologies including XenServer, Hyper V, KVM, Parallels and virtual box. They all do the same thing, but ESXi has been doing it better for longer.
How was the initial setup?
Exceedingly simple setup. You can make it more complex depending how truly enterprise your needs are, like stateless implementations of ESXi.
What was our ROI?
Reduced Electricity Bills, reduced hardware and warranty costs. Reduced server implementation time. Increased management and availability of corporate services.
Which other solutions did I evaluate?
Not on this occasion but I have assessed other hypervisors.
What other advice do I have?
Assess why you think virtualisation is the answer to your problem. Research hypervisor choices, perform Proof of Concept exercises with those products you choose to assess and most of all think about the legacy of what you're doing. i.e. what do you want to leave behind?

VMware vSphere 5.5 Review
The industry’s flagship virtualization platform, VMware’s vSphere, reached its latest release in September of 2013 with the launch of version 5.5. I am a ‘best tool for the job’ sort of technologist, and strive to stay impartial and always recommend the right product for the purpose. Currently, this release is better than any other hypervisor on the market in many ways, such as performance, scalability, management, and automation. I make this statement unequivocally and without bias because I believe so strongly in this product. Every environment that I encounter in my job has some sort of VMware infrastructure powering some set of its critical business applications.
The core of the platform is the server-level virtualization hypervisor, VMware ESXi. It is a bare metal hypervisor that gets installed on each server, and the installation footprint is as low as 2GB! Most of my new installations either run from an SD card embedded on the motherboard, or a certified USB key.
The centralized management portion comes from the vCenter Server. It provides relatively simple management for the environment, and unlike some of VMware’s competitors, vCenter Server is included with the vSphere suite of products. A web-based management interface (unfortunately Flash based at the moment, so iPads need not apply), in addition to a fat client, is available for remote management.
The scalability of the product is simply incredible. A single virtual machine can now scale up to 64 vCPUs and 1TB of vRAM. CPU and memory overhead take a benchmarking team to determine the virtualization ‘wedge’, or performance penalty, which the virtualization layer imposes on performance. Storage latency is under 100 microseconds per I/O. at this point, the VMware ESXi hypervisor layer’s impact to performance is so minute that I consider it functionally transparent.
It has the capacity to run over 85 different operating systems, well beyond its competitors. Bells and whistles like vMotion and Storage vMotion, shared-nothing vMotion, Distributed Virtual Switches, capacity management features such as Storage and Network I/O Control, and capacity management tools such as VMware vCenter Operations Manager (Foundation version included at no cost) stack up to make this the most flexible, scalable, and capable virtualization platform on the market today.
My home lab is completely virtualized with VMware vSphere 5.5 is running at its core. Anywhere from three to six hosts are powered on at any given time, and can handle anything that I need to replicate a problem encountered at a client site, or tinker around with learning scenarios for continuing self-education.
Add-ons to the core hypervisor, such as Site Recovery Manager, vCloud Director, vShield, and vCenter Operations Manager continue to enhance the platform, and add that much more capability and flexibility into an environment that is already the flagship of the industry.
The core VMware vSphere suite is capable of handling just about any application workload that I have ever ran across, and is suitable for any datacenter at tiny businesses all the way up to Fortune 50. Leverage VMware’s vSphere to let your infrastructure move at the speed of the business, not of the IT department. Welcome to the cloud!

I have used everything from just a single server with local disks all the way up to the large VCE vBlocks. It all really depends on the workload properties of those individual web servers. Do you know how utilized the current web servers that you have are? What sort of IOPs and throughput requirements do you have? Usually web servers are CPU and memory intensive but not very disk hungry.

Easy management for backup and security
Pros and Cons
- "Reduces downtime."
- "Integration with different platforms could be improved."
What is our primary use case?
My primary use case is to consolidate the number of physical servers required. We created our motion machines out of it, and it acts as very easy management for backup and security.
How has it helped my organization?
VMWare vSphere has really helped us grow as a business, and going for a virtual backup solution has made my life so much easier.
What is most valuable?
The most valuable features are High Availability (HA), which reduces downtime, and Fault Tolerance (FT), a mirror solution that ensures no data loss. Its vMotion feature is also valuable, as it allows me to move all my virtual emissions to an available host before performing maintenance. I also value a feature called Distributed Virtual Switch, which allows me to create a private VLAN and do L2 management and switch management.
What needs improvement?
An area for improvement would be integration with different platforms. In a future release, I would like to see a feature that alerts the user if they make a mistake with configuration or if there is a vulnerability.
For how long have I used the solution?
I've been using this solution for seven years.
What do I think about the scalability of the solution?
This solution is scalable - it can go up to 64 nodes on the cluster in terms of storage.

Which solution did I use previously and why did I switch?
Previously I also worked with Hyper-V, but some of my Linux machines were having problems with it.
How was the initial setup?
The ease of installation depends on your organization's infrastructure - it can be very simple or complicated depending on what you want it to do.
What other advice do I have?
If you want to reduce your costs, I would recommend going forward with virtualization. I would rate this solution as nine out of ten.

There will be no performance issues as long as you run the correct no of vm that is supported by the hardware.
Here is a simple calculation to find out the no of vm you can run on your hardware.
A Hard disk with
7,200 rpm - 100 iops
10,000 rpm-150 iops
15,000 rpm- 200 iops
For Example : You have 9 Hard disks configured in Raid ,Count the no of hard disks that contribute to the storage.
In this case all 9 hard disks contribute to the storage.And the hard disk has a 10,000 rpm speed so the no of iops is 150
Hard disk*no of iops=Total no of iops
9*150= 1350
if we would like to run 40 virtual machines
1350/40 = 33.75 each vm would get around 33 iops which would give you no performance issues.
Instead you chose to run 50 vm
1350/50 = 27 each vm would get around 27 iops which would cause performance issues.
