IBM PowerHA SystemMirror vs. VMware vCenter

In every organization, we have some of the critical applications in on Premise datacentre were a lot of dependencies in a picture in terms of application as well as a business where we can make highly available to this application by using Power HA Systemmirror by using this we can avoid last time surprises.

The VMware vCenter server is very useful in maintaining the CPU/RAM/datastore resources are balanced when there are multiple ESX/ESXi host servers. It is clear what resources are being used, and it is easy to migrate VMs to different ESX/ESXi hosts. Being able to remotely connect to the VM servers in vCenter when you cannot have other remote connections helps in maintenance and troubleshooting.

• VSAN storage management and redundancy - high performance IO with built in fault tolerance across the cluster, not reliant on a single hardware item
• VM fault tolerance. The ability to relocate a running VM and restart VMs from failed or isolated nodes
• Resource management and alerting. Tracking load across physical systems and allowing us to rebalance for better utilisation

• IBM Sybase replication has been an issue for those who don't [use] MIMIX on their systems to keep the Sybase up to date.
• The graphical interface really needs an update.
• Technical support isn't as responsive as it should be.

• Currently, the HTML 5-based vSphere Client lets you manage the essential functions of vSphere from any browser, however, it would be nice if they would port all management functions over to the HTML 5-based Client.
• Performing updates and upgrades to the infrastructure is a bit challenging for someone that may not be as intimate with vSphere. I think the updates/upgrades should be more integrated into the UI and provide the ability to push to the hosts, etc...
• It would also be nice to have a more robust snapshot management tool to prevent snapshot overgrowth. It would be nice to be able to set a lifespan for the snapshot(s)

We are very dependent on this software, it has become a much needed tool to perform the daily tasks that are required to maintain the virtual server environment. VMware has become very pricey over the years, so we are looking for alternatives for cost savings strategy, but nothing has been found to be on par to what we are currently using

I work with vCenter for 10+ years and i love it. I can find my way around and can help building and expanding the platform. It is easy to use and there are a lot good communities for the extra support when needed. Even the Homelab community is of great value.

VMware support has always been fantastic and they have been invaluable in solving tougher issues that have been run into. Most of the time, any oddities encountered are fixed by available updates. This can be deduced by support quickly with logs within vCenter. We have not run into something yet that support was unable to help with. They either have a solution already, or they are able to find one quickly.

Since moving away from the Windows Server hosting the vCenter application and instead using a virtual appliance, it has become much easier to implement and deploy the new versions. We can easily create a snapshot or clone of the vCenter vApp to ensure any problems encountered during the upgrade can be mitigated with a fall back to the old version to prevent unscheduled downtime.

As I am having long experience with this so no doubt, I am very confident for it where I can deploy easily and manage easily in terms of any issues can go with multiple logs and take further actions on it to fix the issue in a swift manner which matters a lot to me. That's why I have given higher priority to it.

Citrix Xen Server.... Great Hypervisor but very limited in terms of functionality

MS Hyper-V... [VMware vCenter Server] is better for almost everything and appliance form makes a clear winner for security and ease of deployment

• The positive impact of vcenter is definitely felt in larger organisations in terms of being able to manage multiple servers all in one environment
• It will decrease the amount of time your server engineers will have to spend in the server room or datacenter.
