We performed a comparison between Oracle Exadata and VxRail based on real PeerSpot user reviews.
Find out what your peers are saying about Snowflake Computing, Oracle, Teradata and others in Data Warehouse."They just have a lot of products, and they work well together."
"Oracle has reliable solutions and this one is no different."
"The performance of the data is the most important part."
"The data replication is very good."
"The most valuable feature of Oracle Exadata is the smart scan. We have large TB sessions of approximately 100 per second for each of our three instances. The smart scan allows us the obtain data in time in the enterprise manager."
"Exadata is also a very stable environment. Their Smart Scan feature is great for every banking environment and financial institutions willing to implement it."
"What I like most about Oracle Exadata is its smart scan feature. I also like that it supports higher capacities and it's high-performing, so my company can use Oracle Exadata for massive databases."
"A very stable solution, which we have hardly any problems with."
"What I like the most in terms of features is the fact that the VxRail update can be done in one week. It takes much less time to do a whole server upgrade and an infrastructure update as well."
"I like the new releases that Dell EMC is doing with VMware. They are allowing for flexibility across the hybrid cloud. This allows organizations to use containers and to be able to move into the public cloud, but also not have lock-in. They can come back to the private cloud when they want to, so it's creating a lot of flexibility across the stack."
"It gives us tons of flexibility. We can create new machines, then destroy them if they don't work out. We test a lot of use cases that may or may not play out. We can build all types of scenarios into virtual machines that we may or may not use. If we don't use them, we just turn them off, no using up resources."
"It makes for easier deployments through automation and improved accessibility."
"I have found that the admin deployment, monitoring off-premises, and the many services important features. Additionally, the solution has good integration."
"This is a good solution if you want to deploy an ACI Environment but don't have all the necessary resources."
"It's very easy to upgrade."
"It is truly a hyper-converged infrastructure, so everything is there together."
"The cost of the solution is high and can be improved."
"Sometimes it takes too long time to get help with technical issues."
"The handling of temp space has room for improvement."
"A room for improvement in Oracle Exadata is that it's not very easy to use in a microservices environment. It's not easy to split databases, and if this was easier to do in Oracle Exadata, it would make the solution better. What I'd like to see in the next release of Oracle Exadata is for it to become more modular, so you can use it in a context where the data layer is spread between many independent services."
"The integration with third-party applications regarding access management security could be better."
"Oracle Exadata could improve by having faster data retrieval. We receive data at four or five seconds and want to reduce that number to one second."
"The initial setup process is very difficult and extremely complex."
"Certification should also be improved. Today, Oracle doesn't certify applications with engineered systems."
"The scalability is limited to a single cluster with 64 nodes."
"When using hybrid nodes, such as VxRail, there should not be compression and deduplication, only in All-Flash nodes."
"From a hardware and software perspective, there could be an improvement in the sales cycle, as there is a lot of hoops to go through to get pricing on a solution."
"We have some issues, but they are possibly out-of-the-box issues. There was a host that was dead on arrival, and there were some file issues on other hosts. We're currently working actively with Dell to resolve all these issues. Once they are resolved, the product should be stable."
"Having a native replication would be an improvement."
"The implementation of a VxRail, it's straightforward, but the ongoing utilization, and integration, are where it can start to become difficult if you're not used to doing it."
"We have issues at times with the one-click upgrade, which is bugging us. At times, the one-click upgrade does not work or does not work well."
"It might offer better integration with other products."

We monitor all Data Warehouse reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
Although the VxRail is considered as the #1 HCI solution for its reliability & performance, yet unfortunate when it comes to an Oracle solution ... it won't be considered as the best infrastructure choice ... and it's not due to the performance or the architecture, but in fact, the whole blame goes to Oracle license base (core base), as you may see ... VxRail is based on VMWare license, where Oracle condition when you are going to deploy it over VMWare, you will need to license the whole host cores (not only the assigned Virtual cores to the VM), so if you have a VxRail cluster that consists of 4 nodes for example, and each node have dual sockets 16 cores, then although you are assigning only 8 Cores for the Oracle VM, yet you will need to pay for the whole host cores (32 core) which a huge amount of money, and you will pay the double if you are going to deploy in high availability mood.
So you see, the issue is from the Oracle side not from VxRail, Alternatively ... you can deploy all of your application over the VxRail cluster, including the Oracle application, yet for the Oracle database, use a physical server with high CPU frequency and low no of cores ... for example (Intel Xeon Gold 5222 3.8G, 4Core / Intel Xeon Silver 4215R 3.2G, 8Core), and you may use a single socket server which will allow you for upgrading later on.
You may have to pay too much for the Oracle license.
You can try the HPE Synergy platform so that dedicated two physical nodes for Oracle with less core count, REST apps and other VMS run on an HCI cluster managed in the same frame.
