Open source, cross-platform, virtualization software that enables developers to deliver code faster by running multiple operating systems on a single device, used to deploy applications on-premises and to the cloud. Oracle VM VIrtualBox is Oracle's cross-platform virtualization offering, acquired with Sun Microsystems in early 2010. The software was originally developed by Innotek GmbH.
It's well suited for a VMWare Esxi cluster setup. You are guaranteed to have the same CPU chipset to ensure the servers on the cluster are compatible with each other. We've had to stagger the purchase of systems by six months and have had compatibility issues. It's also well suited for I/O such as MS SQL or Oracle databases, Exchange servers, domain controllers. Pretty much any server setup will work with no issues on the HPE Proliant DL line. It's less appropriate as a NAS server, we had purchased one that ran on Windows Storage. Since it was more or less running Windows as a single controller, we had issues where it has locked up and caused an outage.
It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.
iLO Advanced - I feel like this is just a money grab. Give me the remote features, at least the remote console, with the purchase. I'd be OK with paying for the advanced license for more centralized functionality, but straight remote sessions? That should just be there.
Software entitlements and online interaction are a little wanting. This isn't the hardware per se, but enterprise products are often heavily tied to online services and tools and that could be a lot better.
I have had issues in the past when it has come to resizing VM disk storage. The issue is entirely detailed here: https://www.virtualbox.org/ticket/9103 -- the problem was caused because of having existing snapshots (which error message output was not detailing). I haven't had to deal with the issue due to my dynamic disk sizes not being small from the start anymore (this is mostly an issue for my Windows VMs where the base disk may need significant size for the OS). It looks like, for a resize, that a merge of all snapshots has to occur first -- one user on that list details a workaround to maintain snapshots by cloning the VM. (Note: 5.2 was just released a few weeks ago, and looks like it should prevent the problem happening in the future by properly informing users that it isn't possible with snapshots).
Certain scenarios, like resizing disks, required dropping into a terminal as there were no options to previously do so via the GUI. According to some recent posts, I've seen that v5.2 has added disk management stuff like that to the GUI (or will be adding it). I'm comfortable with dropping into the terminal, but in a teaching scenario or when evaluating the learnability of the tools, it complicates things.
We have been using these servers for many years now and we have used different generations of this product line. We have never faced a catastrophic issue using these and even the smaller issues that we have faced have been dealt with by the technical support team of HP. They have been a reliable partner in our data center.
Easy and quick to use. Runs at sufficient speed even with 5/6 VMs running, and can handle a bridged network with ease. Easy to disassociate from the host to ensure the environment built within VB is quarantined should anything happen, meaning no risk to physical hardware. Quick to pick up. Quick to add new machines. Cloning feature very quick and comprehensive. I've never had a VM crash or freeze.
Overall, HPE support meets our requirements. They offer handy 24x7 phone support with clear case resolution interface. Engineers from HPE know their hardware and software. They are polite and help to find quick solutions for their customers. We don't need to prioritize our service requests to account managers to find how to fix or improve our service support.
I've used Dell poweredge servers and they were great too, but I found remotely deploying HPE hardware was significantly easier and faster. One thing I love about HPE is when i got to deploy an OS remotely via iLO I can utilize the virtual media URL as opposed to mounting an iso. these eliminates the SSL overhead and the OS can be deployed in under an hour. Mounting an ISO has proven reliable but due to the SSL overhead it can take hours. In addition i found im able to register my HPE hardware with HPE and they provide me a clean IT dashboard of all of my hardware and they give me alerts as to expiring support coverage, if a server is down or reporting an error. its a very solid and reliable solution all around.
VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition
The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.
Allowed us to move forward with running web-based applications and to scale them as needed.
The lack of future driver support has made it difficult to consider upgrades, we may need to go with more expensive hardware in the future to be able to maintain upgrades.
While we have not realized all the business growth benefits we expected from this investment, we have had much more flexibility and options when we need to change our environment to meet the business needs.
For personal use, there is no monetary investment, I am running 5 CentOS servers flawlessly in my home lab.
Saves a ton of money in an enterprise environment by not having to purchase physical test servers. (Cost of Enterprise product is way lower vs Cost of standing up physical servers and/or cloud servers)
Makes virtualization very easy and friendly for everyone for test instances.
