I have never implemented them as part of an organization, but I worked with these rack servers while providing support for customers.
During the period of time I was providing tech support for this product line, I was able to see that its fault tolerance is really high, providing the capability of a reaction against a “disaster” and the failure rate is really low.
Obviously, you will still have hardware failures, but it is not something you can easily fix. This is more about the regular hardware failures that you may get on daily basis such as a bad HDD, NIC failure or regular hardware failures that may be present due to the normal workload of the server, meaning that they have or exceeded the lifetime or they are presenting a huge workload.
Regarding the normal functionality of the server as is, the only improvement I would say is to continue with the research and the development of higher workload capacities as the customer needs are constantly growing, therefore the demand for what the product requires to do will also grow, to avoid the demand to elapse behind the improving of the technology needs to be continued. It's tied to the needs of the end users and any new features that they would require in order to better manage their organizations.
I’ve worked with these products for over three years providing technical support for the HP ISS industry customers. I did not need to use them in a production environment.
I was part of the technical support team.
I used to guide customers with the installation, and the initial setup was always straightforward.
