The solution's most valuable feature is the ability to create a Mount Point Package

They should continue with the certificate for the consequent year as well. They must keep the product up and running for a long time as it is currently static. There are a lot of challenges as well. Sometimes, the mount point gets lost depending on link failure or census problems. The solution works on a standard script, but it has many tech issues to fix with the OS. You have to keep checking network connectivity, OS connectivity, etc. If any of these fails, then you do not get the certificate.

During failovers or site switches it integrates the storage and ensures the transition of your applications

In terms of interoperability and compatibility, every time new applications and database levels are released, a thorough compatibility check is conducted in PowerHA. IBM consistently ensures compatibility, especially in the open systems environment and within the Unix platform, where software compatibility challenges are prevalent. Regarding components controlled under PowerHA, IBM occasionally must address compatibility issues by providing fixes and releases. Despite this, the product exhibits stability. However, the main issue arises when components are updated, requiring IBM to release corresponding fixes. This process may take some time, but it is routinely addressed. Regarding product stability, PowerHA is generally reliable, with the only notable challenge being the need for fixes during component updates. It would be beneficial if the software had options for controlling and implementing an active-active setup, although PowerHA is primarily designed for active-passive configurations.

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

Pros

"HPE Serviceguard is stable, it has high availability for production."

"The solution's scalability is excellent."

"HPE Serviceguard is stable, it has high availability for production."

"If there's no activation dependency in your organization, I would go for this solution as you can have one server with multiple virtualizations, which will give you a big ROI in the long run."

"The most valuable features are that it's robust and reliable and that the CP memory can be updated in runtime."

"The most valuable feature is the ability to easily create clusters supporting geo-redundancy."

"I would recommend this solution to others, we have used it for a long time and it has been reliable."

"The reliability is pretty good."

"Business continuity is much better, due to the possibility of patching/upgrading systems without interruption of services."

"But once it is done, it will perform very well."

"The failover is the solution's most valuable aspect."

"The most valuable features of Windows Server Failover Clustering are the ISS, failover cluster, and DC."

"The solution switches over to another server in case the server goes down."

Cons

"Many customers want virtualization or high availability but not on HPE Serviceguard with the appliance."

"They must keep the product up and running for a long time as it is currently static."

"Many customers want virtualization or high availability but not on HPE Serviceguard with the appliance."

"The initial setup could be simpler."

"We are currently looking for another solution because, in many industries, such as eCommerce, they operate 24 hours a day seven days a week and this solution has some downtime which our customers do not like."

"Technical support isn't as responsive as I'd like."

"There are times when we do the system security updates and have to restart the server which is difficult because we need to wait until the end of the day or when working hours are finished. There are service updates that have a requirement to restart the system and it is not convenient."

"They could drop the price or improve the cost of the hyper-converged component of it all. Right now, licensing is expensive and complex."

"The stability is good, except for when something crashes or shuts down unexpectedly, then it can be a bit difficult to reestablish the service in a stable state."

"The standard, non-enterprise technical support could be improved."

"The tool's pricing is high."

Pricing and Cost Advice

"The solution is available at a high price. I rate it as a two for pricing."

"IBM doesn't publish its prices, so it's hard to compare its pricing to know how costly it is."

"The functionality is included in Windows Server licences."

"We are on an annual license to use this solution."

"I would rate the solution's pricing an eight out of ten."

"So if you acquire the Windows server license, you will also get all of the Windows services licenses."

Hewlett Packard Enterprise

IBM PowerHA technology provides high availability, business continuity and disaster recovery. It enables you to deploy an HA solution that addresses both storage and high availability requirements with one integrated configuration, which offers robust performance along with a simplified user interface. Power Systems is committed to investing in - and bringing to market - solutions designed to keep your IT environments resilient. IBM engineers work continuously to optimize IBM Power Systems hardware and operating systems to keep pace with the increasing demand for 24x365 availability.

IBM

Windows Server Failover Clustering provides infrastructure features that support the high-availability and disaster recovery scenarios of hosted server applications such as Microsoft SQL Server and Microsoft Exchange. If a cluster node or service fails, the services that were hosted on that node can be automatically or manually transferred to another available node in a process known as failover.
