High Availability works with a series of sub-features that ensure customer resources are online during critical changes.

What is most valuable?

vSphere has many great features. It is very hard choose just one because most of them work together. But, based on the way how vSphere manages all resources provided by the physical system, I believe that the high availability system is the greatest feature of the solution. It works with a series of sub-features that ensure customer resources are online during critical changes.

How has it helped my organization?

We are constantly updating and migrating systems here in my current company. With this product, we can run parallel systems with a low cost and without impacting our customers. With this solution, we can provide more resources, cheaper, quickly, and still keep the integrity and quality of our services.

What needs improvement?

This product already does this very well, but all improvements are related to how physical resources, as well as memory and CPU, are managed . These are the main problems of the virtualization, it uses more memory than CPU. We still have problems with memory in virtualization environments, and some cases can present problems of throughput with virtual disks, too.

For how long have I used the solution?

I have been working directly with vSphere solution for about four years, but I work with virtualization about six years.

What do I think about the stability of the solution?

This solution is very stable. Hardly ever do critical issues appear in the environment, and most analyses that are done in the system are about performance improvements.

What do I think about the scalability of the solution?

No, this solution is prepared to expand or decrease as necessary.

How are customer service and support?

Customer Service:

It is great. They really have a good service.

Technical Support:

The support service is very efficient. They are fast and usually they have a great technical knowledge beyond an effort to solve your problem.

Which solution did I use previously and why did I switch?

I work with more than one virtualization technology. The solution implemented varies according to client requests.

How was the initial setup?

The implementation of the solution is relatively simple. Of course, you need to have some knowledge about infrastructure to be able to create an environment without performance issues. But in general, the deployment of the vSphere system is easy. Just some feature configurations need to be really studied to improve if they really have to be implemented. VMWare provides all the documentation necessary to implement and manage vSphere throughout your environment.

The most common problem in implementing this solution is the incompatibility with some physical hardware, but it was more frequent in the past. All current physical hardware can support virtualization technology.

What about the implementation team?

The implementation was done in-house.

What was our ROI?

This solution is recommended for environments considered medium and above (in the number of servers and hosts). If you are intending deploy this solution to small environments, the cost-benefit is not worth it. VMware provides a free license to be put in small environments, but all the good features of the systems will be disabled. For smaller businesses, I would recommend another solution.

What's my experience with pricing, setup cost, and licensing?

As prices vary, the ideal would be to contact a direct sales team, and report the company's needs so they can point out the best license to use.

Which other solutions did I evaluate?

As I said, I work with more than one virtualization technologies. Beyond VMWare vSphere, I've worked with Microsoft Hyper-V, which is a great virtualization solution too.

What other advice do I have?

It is necessary to be sure about the systems that will be migrated to a virtualized environment. Although nowadays virtualization is at an advanced stage, some systems still present problems when they are migrated from a physical server to a virtualized one. Systems that require too much performance need to have a different configuration, then it's a necessary study on how to implement them.

Replication: VMware vSphere vs. Veeam Backup

VMware introduced replication in vSphere 5.5. The biggest limitation is that it only provides a single restore point only. This is an immediate show stopper for most customers. Multiple restore points are absolutely essential, because just like "good" data, any corruption/virus/dataloss from the source VM is immediately replicated to target VM, and if you don't spot the problem and perform failover to replica fast enough (before the next replication cycle) - which is going to be impossible in most cases - then you are done.

Other limitations
• No failback
• No traffic compression
• No traffic throttling
• No swap exclusion
• No network customization (network mapping)
• No re-IP upon failover
• Minimum possible RPO is 15 minutes
• Basic VSS quiescing (no application-aware processing)
• Works within single vCenter only
• No ability to create container-based jobs (explicit VM selection only)
• Limited seeding options: cannot seed from backup, or using different VM as a seed (disk IDs have to match)
• Different ports for initial and incremental sync required
• No good reporting

Also, be aware that biggest marketing push around vSphere replication is technically incorrect statement!
“Unlike other solutions, enabling vSphere replication on a VM does not impact I/O load, because it does not use VM snapshots”

It is simply impossible to transfer specific state of running VM without some sort of snapshot even in theory! In reality, during each replication cycle they do create hidden snapshot to keep the replicated state intact, just different type of snapshot (exact same concept as Veeam reversed incremental).

PROS: No commit required, snapshot is simply discarded after replication cycle completes.
CONS: While replication runs, there is 3x I/O per each modified block that belongs to the replicated state. This is the I/O impact that got lost in marketing.

Unlike VMware replication Veeam takes advantage of multiple restore points.
For every replica, Veeam Backup & Replication creates and maintains a configurable number of restore points. If the original VM fails for any reason, you can temporary or permanently fail over to a replica and restore critical services with minimum downtime. If the latest state of a replica is not usable (for example, if corrupted data was replicated from source to target), you can select previous restore point to fail over to. Veeam Backup & Replication utilizes VMware ESX snapshot capabilities to create and manage replica restore points.

Replication of VMware VMs works similarly to forward incremental backup. During the first run of a replication job, Veeam Backup & Replication copies the original VM running on the source host and creates its full replica on the target host. You can also seed this initial copy at the target site. Unlike backup files, replica virtual disks are stored uncompressed in their native format. All subsequent replication job runs are incremental (that is, Veeam Backup & Replication copies only those data blocks that have changed since the last replication cycle).

Conclusion:
Veeam Replication really stands out on top of the feature lacking VMware Replication. The numerous missing features like taking advantage of multiple snapshot replications, to help insure data integrity, no failback, no traffic throttling and no traffic compression etc., translate to only using VMware replication for simple use cases.

VMware's replication is quirky and buggy. With every release the product changes. We have been using it and are getting ready to move to Veeam as VMware can not get their replication stable. Currently if a volume has issues replicating under many situation you will not get any alert from vcenter and the status will show green/OK. VMware support says that is normal, status is showing last status? HUH? If it fails that is the current status and should reflect that not the last known good, what is the point. I can see why more and more people are looking to move away from VMware. They are in denial.

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.

Offers a myriad of features
Pros and Cons
  • "Once you have everything configured, it is relatively straightforward."
  • "When we talk about the overall private cloud stack, I would prefer for it be a lot more seamless."

What is our primary use case?

A typical use case for vSphere would be general virtualization, primarily, where we're deploying either Linux or Windows-based workloads. We do have a lot of design-ready nodes we use for some of our clients. We also use Tanzu, from an application development container, microservices type of solution as well. 

What is most valuable?

VMware vSphere is replete with about a gazillion different features. In the context of vCenter, everything has been amalgamated into a single appliance. It's much more simplified at deployment. Because of that, immediately I would say the most useful feature is the Lifecycle Manager, VLCM, that is now available. So, what used to be the VMware of Data Manager has now changed to the Lifecycle Manager. Those changes are really, really useful.

What needs improvement?

I'm a big fan of vSphere; I have used it since the days of 3.5, all the way up to now. When you deploy it as a complete stack, from vSphere to vCenter to the vRealize Operations, Orchestrator, all the way up, you're into your NSX login site, the entire cloud stack. By the time you're done, you begin to feel, "do you really need so many different pieces that you need to connect? Could it not just be a single, unified product?" I'm not saying the integration is difficult. It is seamless. But it gets to you at a point. There are times where you really begin to think, "I got this." Not, " it should be much easier than this."

I can't think of anybody on the planet who would actually have issues with vSphere. vSphere is as stable as the word stable gets. When you do the entire stack scenario unless you're doing something like VMware Cloud Foundation on VxRail, wherein it becomes a much more seamless solution where you are using discrete hardware, you're creating the entire cloud platform. It gets a little tedious doing all those workflows at times.

From a management center, particularly referring to the private cloud stack, I would prefer for it to be a lot more seamless. There are competitors, Cloud Management Platform or Morpheus, for example. It's a product you deploy and you're good to go. With this, there are so many different pieces to connect. It grows on you.

For how long have I used the solution?

I've been using VMware for a long time. As as a DC architect, I use it day in and day out.

What do I think about the stability of the solution?

If you're looking for any hypervisor, vSphere is not a gold standard, vSphere is the gold standard. There's no single other option. When it comes down to it, if I can afford it, vSphere is the only one that I'm going with.

How are customer service and support?

There have been cases with vSphere itself, but the fact is that VMware support is great. 

I have had clients who have faced issues in the context of hyperconverged infrastructure. A problem in the networks assumes a lot more significance in the context of HCI, and VMware support is awesome.

How was the initial setup?

I have no complaints about the setup. The integration is seamless. When you put together all the various pieces, you build an entire private cloud stack. At that stage, once you have everything configured, it is relatively straightforward. But it is not a single homogenous unit.

What's my experience with pricing, setup cost, and licensing?

The licensing is perpetual licensing that you pay for once.

As far as the price of the license, I can't think of anyone who will say, "I'm happy with the pricing." There's always room for improvement. But, you get what you pay for. It's as simple as that. With vSphere, from my perspective, I don't want problems. I want it to be as seamless as possible. That's unfortunately why you've got to pay for it.

What other advice do I have?

Regarding this solution, vSphere is the gold standard. It has been there for 15 years, and you're not going to find people who are dissatisfied with vSphere. You're not going to find people complaining about vSphere. The only thing you will find is when we talk about things like VxRail, things like that, where issues can come. vSphere by itself, I can't think of anybody who's not happy with it.

I would rate vSphere a ten out of ten. You're not going to find anything better.

Which deployment model are you using for this solution?

Hybrid Cloud

We are system integrators. We use a wide range of hardware and products.

On a daily basis, we work with servers, virtualization, VMware, and EMC storage boxes, as well as pure storage.

Our clients have tried Hyper-V as well and other solutions, but the consistency is better and there are fewer issues with the vSphere interface.

How was the initial setup?

The initial setup is not complex. 

It may be complex for the users, but not for the IT person; it is not a problem, and at all difficult

What's my experience with pricing, setup cost, and licensing?

The licensing and pricing need to be improved. 

The price is not an issue for our mid-sized or large-sized customers, but it can be expensive for our smaller customers.

We found this to be much stronger and easier to deploy compared to other solutions we've used
Pros and Cons
  • "The features that I have found most valuable are the overall good ease of use and the good interface which makes it very easy to migrate from one bare metal to another. These are the two things which I like about it."
  • "They should improve their storage management part. vSphere has its own file system type, called VMSS, and that file system doesn't report on proper data usage or things like that. There are certain loopholes wherein it sometimes shows you erroneous data. Again, their VMSS file system, their data storage management system, and its reporting must be improved a lot."

What is our primary use case?

It is a private cloud and it's on a standalone Bare Metal system. On the private cloud environment we provide virtualized computers for different users.

What is most valuable?

The features that I have found most valuable are the overall good ease of use and the good interface which makes it very easy to migrate from one bare metal to another. These are the two things which I like about it. There are certain things as well which I don't like.

What needs improvement?

In terms of what could be improved, they should improve their storage management part. vSphere has its own file system type, called VMSS, and that file system doesn't report on proper data usage or things like that. There are certain loopholes wherein it sometimes shows you erroneous data. Again, their VMSS file system, their data storage management system, and its reporting must be improved a lot.

There are certain features which are called VCE which are available as a separate suite for this VMware cloud. The networking is almost integrated within the vSphere so it would be really helpful for the implementation team if they also had an orchestration for a different storage. There might be multiple OEM storage in the back-end, for example, that could connect with the vSphere while the vSphere shows it to the front-end user as a single storage. There is a lot of scope in terms of managing hybrid storage at the back-end of vSphere.

For how long have I used the solution?

I have been using VMware vSphere for around six years.

What do I think about the stability of the solution?

VMware vSphere is stable in terms of the computer virtualization and it's also scalable. We can go ahead and make HA clusters, but as I said, in terms of the storage stability, there are certain issues because sometimes it gets confused when showing you the actual status. The back-end of the CLI shows you certain data and the front-end shows you different data. That's where there are certain issues with the reliability, but otherwise, it is quite robust and it's scalable.

What do I think about the scalability of the solution?

We have more than 60 people using the different platforms. The functions include several web developers and a lot of finance applications which are running on Oracle and on different RDBMS's.

How are customer service and technical support?

They have a wonderful technical support team. Additionally, there are a lot of blogs, forums and community support available over the internet where you do get a lot of support as well. So it's not always necessary to reach out to their technical assistance team. They also have wonderful documentation available that is quite helpful in terms of resolving a lot of issues.

Which solution did I use previously and why did I switch?

This was a first implementation of vSphere for us. They have a hybrid environment where there is a Hyper-V running their Oracle with VirtualBox running across. We found this to be much stronger and much easier to deploy and hence we thought to continue with it.

Also it supports a wide range of operating systems.

How was the initial setup?

The initial setup is very simple, not complex.

I would say from a completely blank bare metal to the private cloud, it took us around a few hours. Not more than that.

What about the implementation team?

We implemented it ourselves.

What other advice do I have?

I would recommend VMware vSphere to potential buyers. I will always do that. It's highly recommended to go with the entire vSphere Cloud Suite rather than only just going with the Hypervisor. But if you go with the entire suite, it's really wonderful.

On a scale of one to ten, I would rate VMware vSphere an eight.

Which deployment model are you using for this solution?
