VMware vSphere Pros and Cons

VMware vSphere Pros

The features in VMware vSphere data recovery are excellent. Sometimes I've deleted an entire server before and was able to recover the deleted VM. I just used some command line tools and I was able to restore the deleted VM.

We are able to increase the density of the virtualized servers and, with the increased density we have a lot of page sharing as well as memory sharing.
It is absolutely simple and efficient to manage. We can bring in people who have never been exposed to vSphere or virtualized environments and they're still able to support it from a server standpoint. The training time as well as the adoption rate, for a junior technician or somebody coming right out of college, is very good.

One of the most valuable features that vSphere has is its HA and DRS protection, where it can simply make sure that all the machines are always where they need to be and how they need to be taken care of. We have a lot of servers and services for emergency services for police, fire, and the like. We have the ability to use DRS as Anti-Affinity Rules to make sure that those redundant server pairs always stay away from each other. But then, if anything would happen to one of them, we have HA to be able to come up and bring it right up and going again.
Security-Features; vSphere does offer quite a bit of security stuff built-in. It is nice to know that we can have the virtual machines encrypted, so that if somebody were to get a hold of any of those files, we don't have to worry about them actually being used. Since we do have so many different departments and areas with a lot of people that need access into the solution, we can use the role-based access controls to really restrict and control who can do what, so everybody can do what they need to do, but they can't do anything else past that.

vMotion radically changes the way we think about how we can operate a large infrastructure, and notably, in terms of proactive maintenance.
An important vSphere feature from a security perspective is VM encryption. As is the right thing to do in this day and age, security needs to be the number one concern for any IT operator. While there are security solutions which can be delivered at the physical, hardware layer, they don't necessarily address all of the requirements from an encryption perspective. Being able to have VM-centric, VM-level encryption is a great feature of vSphere.

Ease of support is one of the main features that we have with it. We're able to take Snapshots before doing updates to make it easy to roll back if something does happen to go wrong.
The visibility that we have of our VMs is also important. What's being applied? Who has management of them? Laying it out in a virtual environment allows us customization for our students. We're able to respond to the students' needs much more quickly than we could in a physical environment.

With the current compliance options that I have to go through, it's very nice to have a lot of the encryption built in. It checks a lot of boxes for the federal level so I don't have to either bolt something on or have something on top of it. Having it native and integrated into the system makes things much easier.
being able to manage a lot of servers in one pane of glass makes things a lot simpler. Basically, a lot of things just happen in one area. You can roll things over, move things around more dynamically, without having to hit multiple systems.
Valuable features include VHA, DRS, VMotion, and redundancy and failover; any DR situation.

The most valuable feature would be the slight changes they've made to VMFork instant cloning, in which they have abstracted out the parent-child relationship in cloning, in which certain features, like HA and DRS, are now usable on that parent virtual machine. That is wildly amazing and something that wasn't available until 6.7.

The redundancy, the failover, the ability to stay up and running 24/7, all the various tools that are in there, high-availability, DRS, are very critical to us.

One of the things I like with the web client, versus the thick client, is that we're able to access all the vCenters that we manage. With the thick client, you have to log in to one vCenter at a time.

What I like about it is being able to see my entire organization, especially with some of the newer enhanced links. All of my data centers show up in one view and I can see every server that's running. I also get performance statistics so if there are issues, major problems going on, I can see them.
From the interface, you see how much CPU utilization and RAM utilization that each one of those hosts is giving you. You can tell ahead of time when you need to start expanding the environment. And with VMotion, you expand the environment and then let DRS have at it and walk away.

We want to see improvement from VMware with security. We want minimal downtime. We want automation. We want to deploy more efficiently.

In the last couple of years, the breaking apart of specific added benefits and charging license upcharges for them. That would be the only negative thing that I have to say: As a large consumer of the Hypervisor, we have a hard time justifying the cost of utilizing the extra products, especially when it's a couple of grand here and there, a couple of hundred dollars here and there. It's hard for an IT administrator or an architect to sell to upper management. When they're seeing so much ROI from the Hypervisor, it's hard to show them that there is extra value in the additional products that can be tied on top.

I met with the lead solutions architect for vSphere, and one of the things that I really kind of sat him down on was, "What's the deal between these Custom Attributes and these Tags? What are you trying to do with that?" He said, "So here's the deal. I know that they're halfway done and we have a vision of where they're all going, but we'll get it there." That that would be a great ability, to keep all that metadata about your virtual machines inside the solution and staying with the machines.

As we continue to push mission-critical workloads into vSphere, and those workloads are not readily protected at the application layer for availability, continuing to increase the size limitations on FT-protected VMs would be a great advance.
It's inherently complex. Operating a large virtual infrastructure is not an easy task for anyone.

I would like to see a little bit more visibility regarding errors. When an error does occur, there are times where it says "Unknown error" or something to that effect, and it doesn't necessarily give you a lot of metrics. If you go online and you give a description of it, normally the VMware forums can help you find out what it is, but I'd like to see a little bit more visibility from the software itself regarding what's going on: "This went wrong, this is why."

Not having to buy something from a third-party to scan the actual hardware components, like the hard drives and the port containers and fan speeds; not having to bolt something on and go through another vendor, would be helpful.
the HTML version of things needs to get a little bit better. The vSphere side of things gets a little difficult to manage; right-click, in some browsers, doesn't work as well as it used to. I'm seeing a little bit of general latency that we didn't used to get with the thick client, although it's getting there.

In the past, little changes have broken things in vSphere. Going from 6.0, which worked perfectly fine on the Mac Pro, there were certain changes in hardware drivers, when 6.5 came out. Some were no longer present or had been deprecated. As a result, it didn't work on the Mac Pro anymore, which was business critical.

My biggest suggestion would be some kind of a mechanism - and it's almost an AI-type thing, a Siri/Cortana - for where to find how to do certain things. If there was the ability to just type in a basic question and say, "How do I change the VM settings for this?" and it could bring me right there, that would be really awesome.

As far as the web client goes, one of the frustrating things is that it's dependent on different browsers. One day it may work with only a given browser or there may be issues with Flash. So I look forward to being able to use the HTML 5 client.

vSphere itself is great when you don't need to make updates, but any time you have to touch it, unfortunately it's always the little bit of a fight to get it to do what you want.
