Likelihood to Recommend 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.
Read full review First, get the database on Oracle. If you are in an Oracle stack, it would be much better to use the Oracle products. If you are driving a Ferrari, you wouldn’t put a Mercedes engine in it. If you are writing a query, you cannot rely on other brands. Since I'm an architect, when I look for a product, I look for performance. The installation is easy because it comes out-of-the-box and you just start using it. Previous to Oracle Exadata, we were using a normal Oracle RAC service. We were just waiting for this product to come out. I'm currently writing a data warehouse on Exadata. Before this solution, we were aiming for this to be completed by 8 a.m., when our ETLs would finish. With the help of Exadata's special features, this was reduced to 3 a.m. This solution allows us to bring more data within the same time period. It provides us with more subject areas that provide more reports to our users. Our ETL times reduced to 65%, then to 50%.

The one and only FIPS 140-2 Level 4 HSM on this planet Quantum Safe Encryption NOW! AI infusion to every transaction Read full review Customize-able for specific functionality optimized for combination of online transaction or analytical processing. Ability to serve mix workloads with resource management feature enables prioritizing allocation for certain workload. Scale-able on-premise with compatibility for cloud deployment offers flexible solution for organization considering to transition from on-premise solution. Read full review Cons 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. Read full review Patching can often become quite involved and convoluted. It should be more transparent and straightforward. Storage metrics can be difficult and time consuming to obtain. Basic administrative functions can be hard to repair when discovered. Vendor support can take a while to obtain. Generally several attempts are necessary to reach the right area of vendor expertise.

Read full review Usability Once you learn how, it easy. It's different than most other systems
Read full review Reliability and Availability The Z in IBM Z is for zero down time. If you configure your system according to IBM's best practices, you can achieve zero downtime
Read full review Performance Performance is a major part when you configure your system. IBM has many tools to study your system and suggest the appropriate configuration. With the right contract, you can add processing power dynamically and remove it when no longer needed
Read full review Support Rating Support is usually superb, only occasionally dropping to very good. We participate in some of the CD (Continuous Delivery) aspects of z/OS, IMS, MQ, and DB2.

Read full review Implementation Rating I do not personally have any key insights regarding implementation of IBM Z Enterprise Servers as that is what our mainframe architects do.
Read full review Alternatives Considered 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.
Read full review Oracle Exadata Database Machine had the best performance overall hands down. It clearly beat the competition and we were seeing 1000X improvement on
SAP HANA . Oracle Exadata Database Machine beat that without us refactoring our code. To achieve that in HANA, we had to refactor the code somewhat. Now this was for our limited POC of 5 use cases. Given the large number of stored procedures we had in Sybase, we need to capture more production metrics but we are seeing incredible performance.

Read full review Scalability 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
Read full review Return on Investment With IBM Z we really feel a different positive impact on our company. A trustworthy and the most powerful place we have ever. A unique computing platform that helps a lot for the progress of our company. It keeps our data save, encrypted. Read full review Single support from a single vendor with both machine and database from Oracle, which is costing us less. With Exadata, we need less technical manpower and less technical support. A business transaction with the integrated and centralized database helps us focus on other business needs. We don't need to buy additional licenses and Hardware for the next 3 to 5 years.
