Hopefully Long-Distance vMotion is only going to get better.
One of the major new features of vSphere 6 is the ability to vMotion over very long distances. With previous releases of vSphere the maximum network Round Trip Time (RTT) was 10 ms which equates to a distance of almost 400 miles. With Long-Distance vMotion the RTT has been increased to a whopping 100 ms which increases the distance to 4,000 miles – far enough to move a VM from London to New York.
Of course you do still require a L2 stretched network (L2 adjacency) which is where technologies like vSphere NSX come in, but what about the storage?
vSphere 5.1 introduced Enhanced vMotion which combined vMotion and Storage vMotion into a single operation so that shared storage was no longer required – essentially Long-Distance vMotion moves all of the storage for a given VM along with its memory.
This does not sound ideal as you would need to move an awful lot of data between London and New York – it is one thing to move a few GBs of RAM, but 100s of GBs of disk per VM is another matter. The answer to the problem is to combine Long-Distance vMotion with asynchronous storage array or vSphere replication.
For vSphere Replication this should be relatively straight forward as it is integrated into the hypervisor and it works at the VM level, storage array replication will be much more of a challenge as typically it replicates an entire datastore containing many VMs.
This is where Virtual Volumes comes in to play as they should allow replication to be controlled at the VM level. Long-Distance vMotion would need to synchronise the replication and switch the active site – sounds like a complex task, but it would bring tremendous advantages and make Disaster Avoidance available over almost any distance.
I am quite sure that this is something that VMware is currently working on with the likes of EMC and NetApp – so watch this space as hopefully Long-Distance vMotion is only going to get better.

This server class product is very stable, but expensive.
Valuable Features:
This server class product is very stable, I have been using it for more than 7 years, previous versions were named different with less bugs. No downtime.
Room for Improvement:
Pricing can be considered as measure block small and mid range companies. Company needs to think in this direction as well.
Disclosure: I am a real user, and this review is based on my own experience and opinions.
@Radu and Carlos,
If you are installing Vsphere 5.1, it comes with a web interface, just be sure to install it, the software runs on port 9443, it is called VMware Vsphere Web Client. Most of the time, people select the default installation items instead of installing this aspect of the program.

Allows us to create or clone a virtual environment in a short period of time and has good stability and support
Pros and Cons
- "The ability to create or clone a virtual environment in a short period of time for testing is most valuable."
- "An improvement could be in terms of keeping up with the upgrades. The upgrades could be set in an automated way so that the newer features don't require you to manually update, or you get an option to update automatically. This would be a useful enhancement."
What is our primary use case?
We use it to create virtual machines and things like that.
What is most valuable?
The ability to create or clone a virtual environment in a short period of time for testing is most valuable.
What needs improvement?
The enhancements that come out from time to time usually surpass what we need. We tend to upgrade because we do not want to be behind, but our needs don't continually grow. We are not very fast in terms of appetite for new things. However, we do appreciate that there is a continuous improvement, and for us, it is just a matter of being able to spin up a new environment quickly.
An improvement could be in terms of keeping up with the upgrades. The upgrades could be set in an automated way so that the newer features don't require you to manually update, or you get an option to update automatically. This would be a useful enhancement.

Entrepreneur at WindiS
A straightforward setup with good documentation and excellent stability
Pros and Cons
- "The documentation is very good."
- "Sometimes you can't find items and you need to log onto different physical servers to do technical tasks. I don't fully understand why this is the case."
What is our primary use case?
The solution is primarily used to house VMs, virtual machines.
How has it helped my organization?
Virtualization changes radically the IT landscape. Rare are our customers who have not implemented it. vSphere is #1 in hypervisors and offers the flexibility and the fastness our customers need.
What is most valuable?
VM models is a great feature. It allows to create VMs very fast and already patched with the different configurations that the are needed.
The ease to move a VM from a host to another or even to another storage/DC is very convenient. That all this can be done while users work on the VMs is awsome.
What needs improvement?
The graphical vSphere vCenter interface is now in HTML. I'm not very found of it. Sometimes you can't find items and you need to log in to the different hosts.
Some work has to be done with this admin console.
For how long have I used the solution?
I have many years (lost the count...) of experience with this solution, beginning with version 4.0, then 5.0, 5.5, 6.7 and finally 7.0 and use it daily.
What do I think about the stability of the solution?
The stability has been very, very good. I didn't have any crashes. There aren't bugs or glitches. I find it to be a very, very strong architecture.
What do I think about the scalability of the solution?
In terms of scalability, I haven't really had the opportunity to address this as my customers are not very big companies and we have relatively small data centers.
How are customer service and technical support?
I've never had to call VMware. You basically can find everything on the web. VMware's website is very good and there is a lot of information everywhere about vSphere on the web with real experts of the product.
Which solution did I use previously and why did I switch?
No
How was the initial setup?
The setup is straightforward, only a few questions to answer, and you have your hypervisor ready !
What about the implementation team?
Always in house.
What's my experience with pricing, setup cost, and licensing?
The cost of the solution is relatively low. VMware proposes the Essentials kits which are very affordable for SMB companies.
Which other solutions did I evaluate?
I didn't really evaluate any other solutions. I haven't even really looked at Hyper-V, although my clients sometimes ask about it.
What other advice do I have?
We are implementors and our customers don't sometime have any dedicated IT guy. But, as vSphere works well once implemented, there's relativally less to do.
Which deployment model are you using for this solution?
On-premises

Virtualization of servers: Use of the solution to reduce the space usage in the data center. Also, for hyper-convergence, you can virtualize the storage.
How has it helped my organization?
Less space is need. It reduces the space of the infrastructure in the data center. The easy of use with reduced space provides a better use of infrastructure.
What is most valuable?
- vMotion
- vCenter
All the features in the vSphere essentials are great in helping the administrators manage the virtual platform.
For how long have I used the solution?
One to three years.
What's my experience with pricing, setup cost, and licensing?
The only issue with vSphere might be with the cost of its tools and the software.
What other advice do I have?
I think that the solution with vSphere is complete.

Cross vCenter vMotion allows us to perform vMotion from one vCenter to another without the need for shared storage.
Valuable Features:
Cross vCenter vMotion is a valuable feature.
It allows you to perform vMotion from one vCenter to another vCenter without the need for shared storage, like a cut and paste.
This was not possible until version 6 and is built upon Enhanced vMotion.
It requires L2 network connectivity.
Improvements to My Organization:
Cross vCenter vMotion can be particularly useful if you have migration projects, or you simply want to shift workloads to different location.
It can be particularly useful if you have plans to move from a VCSA to a Windows Platform vCenter and vice-versa.
If you have shared resources with public/private cloud, you can move them by establishing several vCenters.
Room for Improvement:
One improvement could be to have the vMotion independent of the SSO Domain.
With Cross vCenter vMotion, it is a requirement to have both the source and the destination vCenter on the same SSO domain. It also requires version 6 and above. You cannot have this between a version 6 and 5.5.
I still experience lag with the web interface
Disclosure: I am a real user, and this review is based on my own experience and opinions.
Having vMotion independent of SSO would be a great thing but more than like would take some code rewrite. Love that idea though. I see a bit of lag in the Web Interface but not nearly as much as previous versions. Not sure what web browser you are using but I find Opera works very well with the Web UI.
