We performed a comparison between IBM PowerVM and VMware vSphere based on real PeerSpot user reviews.
Find out in this report how the two Server Virtualization Software solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The case fileserver on the web server is the most valuable feature."
"IBM PowerVM has the highest clock speed."
"It's in English, so its exceptional qualities make the control environment more flexible, easier, more stable, and easy to recover after issues."
"It is a stable solution with reliable performance."
"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"Active Memory Sharing dynamically reallocates memory of running partitions based on changing workload demands. The memory for the pool is carved out from Physical memory and is made logical memory. The said memory is not available to be assigned to partitions as dedicated memory. A min, max and desired as well as weight is assigned to the memory of each lpar to help hypervisor make a decision in case a condition where priority is to be given to a certain lapr to use the memory form shared pool."
"It is a complete solution."
"IBM PowerVM's most valuable feature is stability."
"It helps to automate the data replication and DR (disaster recovery)."
"We have seen an improvement in uptime. The whole hardware lifecycle process is easier."
"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."
"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."
"I like the capability of logging into one system, then being able to shift over to another system within that single pane of glass."
"We primarily use vRealize to troubleshoot any issues that may arise with our virtual machines, which is the main reason why we believe this solution is excellent."
"It is a very mature solution that is easy to use and flexible."
"Performance; We have seen a performance boost because we have been able to more dynamically allocate either memory or processors."
"The cost of this solution is high."
"A GUI version of VIOS would be a great plus for people moving from Intel-based hypervisors."
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"I would like for IBM to be more focuses on the cloud."
"The product's pricing could be less expensive compared to other competitors."
"IBM PowerVM does not integrate with Microsoft."
"Any improvements that can be made in the interface will go a long way to helping us work better."
"The interface is not user-friendly in places, so it could use some improvement."
"The challenge that we have is keeping the system up to date, as well as having the internal resources to maintain that platform. We're not an IT company, so it's challenging for us to keep the IT resources in-house."
"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."
"The solution is stable. However, it could improve by being more secure."
"They should improve their storage management part. vSphere has its own file system type, called VMSS, and that file system doesn't report on proper data usage or things like that. There are certain loopholes wherein it sometimes shows you erroneous data. Again, their VMSS file system, their data storage management system, and its reporting must be improved a lot."
"The user interface could use some improvement."
"Sometimes you can't find items and you need to log onto different physical servers to do technical tasks. I don't fully understand why this is the case."
"Without a lot of physical RAM on the hardware, it's not very effective. The stability could be improved in cases like this."
"It would be good if the licensing cost of the solution could be cheaper."
