Has empowered enterprises with secure and cost-effective solutions
When discussing disadvantages, I do not see many areas for improvement because we have received good testimonies from every client. IBM gives customers peace of mind. One challenge, which I would not really call a challenge, is that initially people have the notion that IBM Power Systems is quite expensive. However, IBM does not lose deals based on price. This is a message we need to keep communicating to people who feel that IBM is on the high side in terms of cost. We encourage them to have a discussion with us about their total cost of ownership over three or five years. There is a notion in the market that IBM is expensive, which is false. However, once we engage and show them their return on investments and their total cost of ownership savings, they tend to embrace IBM.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Everything looks to have a product superstar in hand: less energy consumption, lower cost, less space, scalable and customizable."
"With each user having its own physical CPU/GPU, enough memory etc. (when dealing with HDI) the overall user experience will be top notch, as to be expected."
"Scalability is great, and that was one of the key bits, as it has the scalability option in which you can fit four on each blade and have the capacity to keep on going."
"IBM Power Systems are secure and have fast processing."
"Power is the best."
"The availability of a solution depends on the requirement of the customer. The most valuable feature is the virtualization. You can have this one system or you can use it for many. They were using almost 120 servers within that specific service."
"We are very happy with Power's performance."
"In terms of the upgrades from previous versions, we definitely see a return on investment, as we get more processor, more CPW, and it's basically the same price."
"We generally find the compute and the processing power, and the ability to handle the load, is far better on the POWER systems."
"The uptime feature is great."
"From a reliability standpoint it has provided us with excellent performance."
 

Cons

"Why not spend the same (or a bit more perhaps) amount on virtual?"
"I think there's room for improvement. It doesn't work properly yet."
"However, with great potential gains, there is a big risk."
"Better manage heterogeneous footprints of all the different operating systems that are out there across one common interface."
"The solution is highly-priced."
"Its management can be made easier because it is not easy to manage. They should also find a new way for migrating from an old Power Systems to a new one. The migration process is currently very complicated. It should be made easier to scale. Currently, its scalability depends on the initial sizing, whereas in Nutanix HCI, you can add whatever you need and whenever you need it."
"The power supplies often need replacing."
"Its pricing could be better."
"They are very knowledgeable but there's some bureaucracy as far as the time to respond goes, as far as getting back to us with what we need."
"IBM Power Systems could improve by having a cloud feature."
"Technical support and documentation need to be improved."
 

Pricing and Cost Advice

Information not available
"The price of IBM Power Systems is expensive and could improve."
"IBM Power Systems is a really expensive product."
"The cost model is great. There is so much built in to the technology, that if you know how to use it you can save yourself a lot of money."
"When there is an error in the SAS drive of 10,000 RPM, my company buys support for 1,500 USD."
"It's more about the value you get for the price. Considering its stability and performance, the pricing is good."
"Price-wise, I rate the solution a five out of ten."
"I give the cost a one out of ten."
"It is designed for a large workload, as opposed to a small workload. For our circumstances, and even as an independent, I can't buy a Power system to experiment on. It can't happen. You cannot buy them."
