Very fast, good memory, and very good scalability

What is our primary use case?

We are primarily using the solution for the BW system of SAP. We also use the legacy reporting, which is very good.

The solution is quite fast.

How has it helped my organization?

We hoped to move all our BI systems to work with HANA, unfortunately, there are a lot of performance issues, even after remodeling the BW models.

What is most valuable?

The memory is the solution's most valuable feature. It's the main feature of HANA. Others are still the regular IT databases that are on storage and are therefore much slower than HANA. The solution is quite fast.

What needs improvement?

Unlike other databases, it lacks management features that legacy databases like Oracle or SQL servers have. They need to make the solution easier to manage and offer tools that make management more effective. A lot of things you have on traditional databases you have to develop into HANA.

For how long have I used the solution?

I've been using the solution for about 3 years

What do I think about the stability of the solution?

The solution is less stable than traditional databases. We have encountered several cases when the database just flows. For some reason, that database took a lot of memory, and when we opened a case with SAP, we had to send a lot of logs, which did nothing because at the end, they couldn't find the root cause for this issue. This happened in several cases. We had production down and that's not acceptable for our business.

What do I think about the scalability of the solution?

The solution is very scalable. We have about 10,000 users.

Each of those is not connecting to the database per se, but we are using HANA to take all the data and a lot of users. Several other software applications are also connecting to it.

How are customer service and technical support?

Technical support is okay, but not great. It seems like there are a lot of SAP support packages that are coming out and lots of versions. For me, this indicates that the product is not quite ready or stable enough.

We've contacted technical support in the past and did not get good results. Eventually, we just created some parameters that we have configured into the system. We solved the problem by ourselves by creating a workaround that avoided the problem. SAP never gave us a straight answer about what we should do in our case.

How was the initial setup?

The initial setup was quite complicated. We had to do a migration, so it wasn't a fresh installation. We had Oracle as our legacy system and had to move everything over to HANA. We had to do half a year of testing and had to do several cycles of tests and migrations before deploying. Once that was done, we deployed over a weekend.

What about the implementation team?

We handled the implementation ourselves.

What other advice do I have?

We use the on-premises deployment model.

I'd advise others to wait until the software will be much more stable before implementing it.

I'd rate it eight out of ten. If it was more stable and more manageable, I'd rate it higher. If people could have the ability to do things on their own within the solution, to read the software logs on their own, and get the root cause of any problem, and not just send it to the support, it would be much better.

Which version of this solution are you currently using?
