    Most of the time, server utilization is reliable and stable during peak times. Truly amazing, this product offers a lot and gets it done in no time without any confusion.It is reliable, too accurate and the performance is top-notch. It seems to be competitive in all virtual energy systems and its connectivity is also good. It's available at a low cost, but it's enough to have as many low-cost, more efficient systems as possible. It's a minor thing, but very rarely, it can cause work interruptions while it can get stuck due to more frequent use such as restless work. These power servers are very efficient and really help when things go wrong. I am using this product to retrieve data much faster.

    RHEV is well suited for organizations that need a cost-effective and flexible solution for their environment. As its vendor-independent software, easily install on any type of hardware. RHEV provides a GUI interface to manage the software, which makes the management of the software easier for the end-user. RHEV is best for non-production or less critical applications. RHEV can be easily integrated with other REDHAT software.

    • RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon.
    • Red Hat distribution integration is seamless as it is integrated into the kernel.
    • OpenStack support enables more customized VM templates and network configuration control.

    Cons
    IBM
    • It would be good if IBM could demonstrate more use cases for Z to potential clients
    • A migration strategy from Open Systems to Z would be helpful
    • Any additional marketing to could explain the benefits of Z/Linux, especially now that RedHat is in the mix.

    • 1- RHVM API is pretty slow, especially after creating a VM it is not possible to retrieve the VM details (i.e VM's MAC Address) fast enough, where we need to place a pause in our Ansible Playbook, make the automation process slow.
    • 2- RHV is still using collected to monitor the hypervisors which is deviating from Red Hat policy for other RHEL based applications to use PCP to monitor, which is richer in features.
    • 3- It will be great if it is possible to patch the hypervisors using other tools such as satellite and not only via RHVM.
    • 4- In the past Red Hat used to present patches in the z release (i.e. 4.3.z), and features in the y release (i.e 4. y), but starting from 4.4 that is mixed together wherein the Z release you get both patches and features, that is not good because that requires a lot of time to test when we patch as it includes features as well.
    • 5- Engineering team has to be more reactive when new feature is requested.

    IBM Z is the best storage solution as it provides the best in class data protection with the cryptographic hardware keys, no loss in data while migration, and a user-friendly interface that makes it easy for develops to understand and has less of a learning curve. This makes it well above the competition.

    RHEV is an excellent product, includes more features, is less expensive, and has rock solid reliability and is backed with the best Red Hat Support in the industry. RHEV uses KVM under the hood which is used by all the big players in the industry (AWS, Rackspace, etc) to lower their overall costs and improve efficiency and profits and that's why RHEV is an excellent solution!

    If you need more processing power, just add more CPU's or memory. The largest system can have close to 200 CPU's and 40 TB of memory. If that is not enough, you can add more physical computers, and connect them using a sysplex
