Product Reviews
ORACLE EXADATA DATABASE X6-2 HC HALF is rated 4.0 out of 5 by 43.
Rated 4 out of 5 by from It provides fast communication between the storage and database. Valuable Features:This is an engineered system by Oracle. It provides very fast communication between the storage and database. A lot of data processing is done at the storage level.Improvements to My Organization:This makes the queries and processing much faster than before; reports can run within minutes which earlier used to take hours.Room for Improvement:Cost is very high, it needs to be made affordable to grab more customer base. A lot of the technical enhancements are being made by Oracle regularly. Now, it is available on the cloud also.Use of Solution:I have used this solution for five years, about the same time when it was launched.Stability Issues:There were no stability issues.Scalability Issues:There were no scalability issues. In fact, scalability is one of its prime features, it is very flexible.Technical Support:The technical support is as usual good from Oracle.Previous Solutions:Earlier, we used SAN and the traditional servers. That was also good and time-tested for decades. This is all together a new concept.Initial Setup:It was a normal Oracle database setup.Cost and Licensing Advice:The price and license costs are high as compared to the normal database setup. It depends on the client's requirements and size of the databases. Clients/ buyers have to take the call.Other Solutions Considered:No other options were available in this category at that time or even now.Other Advice:You should evaluate your requirements and budget.Disclaimer: I am a real user, and this review is based on my own experience and opinions.

Rated 4 out of 5 by from Performance is one of the key features, allowing us to bring in more data. It provides us with more subject areas for reports. And now supporting the Cloud service. Valuable Features:The most valuable feature of the solution is that it is durable. It is a highly relevant option with extreme performance. The extreme performance is one of the key features when you're using Exadata. There are known points that you need to take care of, simply "beware of update".!Improvements to My Organization: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%.Room for Improvement:I would like to see more database features and maybe more archiving features, because we need to do data archiving. I would like to see additional database memory.Use of Solution:My first implementation was in 2009 and still using.Deployment Issues:No.Stability Issues:There's nothing bad to say about Exadata. It's stable, durable, and always up and running. My DBAs do online patches and online backup.Scalability Issues:This product is scalable. We first started with the quarter rack, and then we expanded to the full rack.Previous Solutions:Previous to this solution, we were using a normal Oracle RAC service. We were just waiting for this product to come out.Initial Setup:The installation is easy because it comes out-of-the-box and you just start using it.Other Solutions Considered:We had already chosen Exadata, so we didn't compare this solution with many other products.Other Advice:Get the database on Oracle first. 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.I'm an architect, so when I look for a product, I look for performance.Disclaimer: I am a real user, and this review is based on my own experience and opinions.

Rated 4 out of 5 by from Provides workload offloading to the cell layer. Valuable Features:* Workload offloading to the cell layer* High availability of each component and everything is redundant* Smart scan feature and the flash memoryImprovements to My Organization:* Exadata accelerates the performance to whole applications in the environment at least by 2-3x times than the old hardware.* One consolidated environment for all Oracle databases.Room for Improvement:* The integration between Exadata and Enterprise Cloud Manager should be included out of the box by default and should be agent-less, just discovery only; or, add an embedded and dedicated monitoring and management UBI tool for all HW and SW of Exadata.* Enhance the monitoring and alerts part related to Exadata with EM.* All firmware, OS, cells SW, etc. (quarterly patching for Exadata) upgrade and patching should be easily done through EM.* Physical KVM is required, as in the old version; Cisco management switch is the only single point of failure.Use of Solution:I have used it for three years.Deployment Issues:Some steps failed during the deployment by using one command utility to do all deployment steps by one command; so, we divided the deployment steps, then solved each issue separately until we successfully finished the development.Stability Issues:We have not encountered any stability issues; it is a stable box.Scalability Issues:Until now, we did not scale.Customer Service:Customer service is 7/10.Technical Support:Technical support is 6/10.Previous Solutions:We previously used normal HW, then moved to VMware, then moved to Exadata to get good performance and consolidated platform for DBs.Initial Setup:The initial setup is clear but you have to be careful while filling out the OEDA (Oracle Exadata Deployment Assistant) tool as it will generate an XML file that contains all of the required configurations for everything, like networks, storage, clusters, etc.. This file will be used during the initial setup.Implementation Team:We implemented it through the vendor; I rate their level of expertise about 7/10.Cost and Licensing Advice:At first glance, it is expensive because it contains many HW and SW components and provides high availability, as you have to buy licenses for DB, RAC, packs, and Exadata drivers SW per disk. But, if you are going to use it in a consolidated way for all Oracle databases, I think the price will be reasonable, as you have many DBs. There are many sizes for Exadata, so you have to choose the suitable one for your organization according to proper sizing. For licensing, the minimum license number is 8 cores, which are available for Exadata X5-2 and X6-2.Other Solutions Considered:Before choosing this product, we also evaluated HPE HW including flash memory and SSD disks, but it was more expensive at that time.Other Advice:The team should be familiar with RAC; some HW and network knowledge. The team should understand the new Exadata SW related to the cell layer.Consider the COD feature to pay as you go. Integrating Exadata with Oracle Cloud Enterprise Manager gives you the power of monitoring and managing the box. You can also enable the notification mailer through EM or cell.Disclaimer: I am a real user, and this review is based on my own experience and opinions.

Rated 5 out of 5 by from The Smart Scan and Hybrid Columnar Compression features are valuable. Valuable Features:* Smart Scan* HCCImprovements to My Organization:We consolidated 58 databases from 58 standalone servers into 4 RAC nodes (half rack). We achieved HA with RAC, and saved a good amount of storage with the HCC feature.Room for Improvement:* Storage* License* Overall performanceUse of Solution:I have used it for 11 months.Deployment Issues:We encountered a few bugs, and migration technical challenges.Stability Issues:We have not yet encountered any stability issues.Scalability Issues:We have not really encountered any scalability issues.Customer Service:Customer service is excellent.Technical Support:Technical support is good.Previous Solutions:We previously used a different solution. We switched for consolidation and to use the great features of Exadata.Initial Setup:It wasn't easy to get the new technology in. Going from the traditional storage/server architecture to an engineered system was a tough decision; had to go through several if and buts.Implementation Team:We implemented it through a vendor.ROI:ROI depends on the business needs.Cost and Licensing Advice:Compared to 58 individual standalone servers, the engineered system was significantly less in licensing.Other Solutions Considered:Before choosing this product, there were three options considered and given the PoC to finalize the product.Other Advice:We started with two boxes and in the end, we have two additional half-rack Exadata machines.Disclaimer: I am a real user, and this review is based on my own experience and opinions.

Rated 4 out of 5 by from We have consolidated our infrastructure. It provides scalability, performance, and availability. Valuable Features:It's about consolidation of my infrastructure, scalability, high performance, and availability. These are the main factors that led me to choose this solution, as well as the cost. Exadata saves on my storage costs. All our costs were reduced significantly, and that was the reason why we went back to Exadata.Room for Improvement:On the improvement side, they’re pretty much good. With the latest version, X6-2, we have enhanced the storage capacity. It was 4 TB each disk, now it’s 8 TB each disk; essentially same size appliance with more storage space. That request has been heard and we're able to mitigate that. Increased storage was one thing and they have definitely done better on the IO of flash storage. They implemented that; pretty much good stuff.Stability Issues:We have not had any major problems with stability.Scalability Issues:From time to time, we scale capacity up and out. In system engineering terms, we can scale up to limit. The kind of features we just set it up, I've been able to fit my requirements into that.Technical Support:We have Oracle’s Platinum support, which has been pretty good. However, the people are not always knowledgeable. I always rely on my best contacts in Oracle to get the right support. Even though we have Platinum Support, my last delay was my contacts in Oracle.Initial Setup:Initial setup was very much straightforward. Not as much manpower is required as we used to need. Before, if you wanted to manage a server, you had to have a server administrator, the storage administrator, and a DBA administrator. Now all three functions are combined into one person. A data administrator can perform the role of storage administrator, your host administrator, platform administrator, as well as database administrator. It's like several persons reduced to one.Other Advice:I would definitely recommend this product if cost is not a factor. The implementation costs are, frankly, higher, but your return on investment over a period of time is less. If you're looking for that, then I would definitely advise to go for this product.Disclaimer: I am a real user, and this review is based on my own experience and opinions.

Rated 4 out of 5 by from It has computing power at the storage level, which reduces latency. Valuable Features:Usually, the I/O operation is a more intensive and costly one. In any transaction processing, the I/O is a more expensive operation due to storage and better performance. That's where most of the latency and time would be spent in overall flow. Exadata has an additional service and computing power at the storage level as well which reduces this latency. Usually it's available only on the high-end machines.Exadata as a platform is a complete solution, where you have CPU memory with an additional server and inter-cell storage. That's the beauty of Exadata; IOPS and good overall latency and that's why we like it. We use it for the transaction processing, especially for production.Room for Improvement:In terms of improvement, related to other products when we were running down the physical servers, we ran into some issues. We are always on the latest stack so at this point of time we are self-sufficient. Once we deployed Exadata, we never had to look back, at least in recent times.One improvement would be the limitation on the storage. For example, when we buy with a double or triple CN, it comes with some storage. Once we reach that point, we don't have any other option. This was in the old version. We don't know how it is improved in the current version; maybe there is a way to optimize it and we can have additional storage allocated. In the earlier versions, we didn't have this possibility and we need to upgrade to a later version of Exadata to get more storage.Use of Solution:I have used this product for more than 4 or 5 years.Stability Issues:It's a stable solution but it comes with a price. You get performance and there is a cost associated with the performance. The Exadata tool is best when you can afford. You get best quality, in terms of the overall product features.Scalability Issues:It depends on each case, your use and the company. For us, it is scalable and working for our use.For me, what we have right now is scalable and it is serving our purpose.Technical Support:They have a dedicated team exclusively for Exadata. Whenever we ran into some issues with the tool, they nailed it down. The support was good in Oracle because this is a prestigious product from Oracle. They have their support model.Disclaimer: I am a real user, and this review is based on my own experience and opinions.

Rated 4 out of 5 by from It combines hardware with the software that we use from Oracle. Valuable Features:It is fast and integrated. It combines hardware with the software that we use from Oracle. It's a complete stack, not only for the hardware but the full implementation and delivery, so it’s really good for IT.Improvements to My Organization:We have seen performance and reliability benefits. It's also beneficial from a cost perspective.Room for Improvement:We are using it now predominantly as a hardware stack managed by our company. We would love to see it more as a service; a database-as-a-service offering.Stability Issues:It is very stable; no stability issues.Scalability Issues:No problems with scalability.Technical Support:The SRs that we raise are not always resolved in a timely fashion. Often I'm unhappy.Initial Setup:At this moment in time, it is pretty much a straightforward, almost-manual installation. We're looking for some automation around it.Other Solutions Considered:We also looked at other organizations or vendors, as well. We also looked at the database appliance from Oracle.We decided to go with the Exadata product because of the size of our company.Other Advice:The Nike one: Just do it.Disclaimer: I am a real user, and this review is based on my own experience and opinions.
