Oracle Exadata Reviews

It's pretty simple in my opinion. It's called out the box, and it's called support. Sometimes with the engineered systems based on the support agreement that you have with the vendor, sometimes you hear about problems with your system from them rather than your applications experiencing some issues, and you're having to log a support ticket with Oracle. I think that's huge.

The thing that attracts them to the two products but mainly the Exadata is the storage technology is revolutionary whether it's the only solution of that flavor on the market or not, I'm not familiar with. It's the storage solution, it's the speed, and it's the high availability. If somebody wants 5 or 6 9s worth of availability, a very good place for them to be is with one of Oracles engineered system solutions.

As is always the case with Oracle, when some late-breaking fancy technology gets under their radar, self-invented or perhaps something that they're picking up that they'd like to compete with from another vendor, they're all over it. I can't specifically think of anything myself. Outside I guess of speed and maybe the other two things I could think of are speed and speed, but I'm not suggesting that speed is an enhancement because there's anything wrong with the speed of the system now, but of course we always like to do things in four nanoseconds rather than seven.

I think I would probably give it a capital S. People here peripherally hear about informational stuff that may be going on in the cluster, but as far as catastrophic events that may happen with the cluster, a lot of them in some way, shape or form are not far from self-healing. I think that's a huge advantage of an engineered system.

If you buy a quarter rack, you feel like you need more computing power, you upgrade to a half rack. You go to a 3/4 or a full rack. It's basically I guess we used to call it plug and play except a lot of us found it in the olden days, it was plug and pray. I think they've got that one licked to the max.

Sometimes it's them calling us on behalf of one of our clients, but I would find that once one figures out the best way to work with their support organization in general, but their engineered systems support organization in particular, I can't think anything outside of a world class organization. I would admit that I don't have a lot, if any, experience with the competition, but I don't feel like I need any experience with the competition because of the way they do support those two products.

A lot of the times it ends up being complaints from the user community, and difficulty with strategic activities that the system performs. If you're running a commercial off the shelf application against these engineered system, sometimes it's a little more complex to work with a third party vendor, to speed things up. Mainly it's complaints from the user community. You and I both know that if something takes four seconds all the time and takes seven seconds some of the time, all the people are going to remember is the seven seconds.

I haven't done it on a hands-on basis, but I believe that what I mentioned at the beginning about out of the box is just that. Oracle from my recollection first tried to venture into some form of engineered system in the '90s with HP. It was a red box that you basically took out of the carton and plugged in. I think that's pretty much close to what once you brought it onto the network, exactly what you're going to do with their systems, so I thinks it's plug and play.

Choosing a vendor: obviously cost, high availability, and the strength of the rack technology. It's a corner of the Oracle technology that basically not exactly gets reinvented, but the new features and the new ways of going about to do things and the capabilities of failover and all that is a huge concentration as the product matures, not that it is immature. I think that's a primary reason that people might consider looking at this. There's absolutely no doubt, it's not far from an upgrade basically being done on the fly. There's so many things that can be done online. The plague of course of the '90s and the early-2000s was downtime.

Rating: I'd call it about a 12 out of 10. Of course you have to be able to afford the box. You have to be able to afford the configuration that you're going to be getting into. It's cost-effective for a lot of organizations, but I would rate the technology very high. Some of the specialized mechanisms that Oracle has put in place, especially with respect to Exadata and the late-breaking version of Exadata in particular.

As I said before, I'm not intimately or even somewhat peripherally familiar with the competition, but these guys know what they're doing, and my experience has been in the past that if Oracle ever plays catch-up in a technology spectrum with the competition, watch out. We all know that it's now cheap. It's affordable for a lot of organizations. If cost is going to be something, it's going to ultimately drive an organization's buy or no buy decision. The benefit after the money is spent and an ongoing outflow of cash to the vendor, if it makes business sense for somebody, I don't think they can be in a better place.

Make sure it's the right solution. Make sure that you do indeed need their real application cluster solution, which we affectionately call rack. Make sure it's right for you. It sounds corny, and it's sounds like a cliché, but it applied when I got started in IT in the 1800s, and it still applies. If it's cost-effective, go for it.

The performance.

It makes it possible to deliver high performance Oracle OBIEE applications to our customers.

They need to reduce the cost. It needs to be a true appliance so you don’t have to manage individual components inside it. It needs to provide a better maintenance process, which means no downtime, and true rolling upgrade.

We used Oracle Exadata from 2010 to 2015.

I have deployed OEM 11g and 12c in High availability mode and was not too complicated to implement. I have not tried HA with 13c. However, installation for all the releases have been fine.

We've experienced no issues with performance.

We had some challenges on scalability. That time the only choice we had was to upgrade to a full rack from a ½ rack. However the newer version of Oracle Exadata has flexibility to upgrade. It can add database servers or storage servers not require to add ¼ or ½ racks.

6/10 - not because of people, but technology and architecture. A few times we had issue to completely fail a drive before we can replace it.

We had been using Oracle RAC on EMC disk array with Dell servers until the performance cannot really meet Oracle OBIEE application and some data warehouse applications’ performance requirement. We did look at Netezza and Datallegro, but they didn’t run the SQL that compatible with Oracle. By then Oracle Exadata seemed the only logical option for us. We also had a business reason to purchase Oracle Exadata at that time.

The initial setup was pretty smooth and straightforward.

We had Oracle team to setup the device.

The device performed very well, but the biggest challenge for us was the maintenance. Any firmware, code or OS upgrade took long time, which requires a downtime window. The rolling upgrade would even take longer so we never tried it. I heard that the new version of Exadata should be improved in this area, but we have moved off Oracle Exadata platform. The DR is another challenge since ideally you would want have to a Exadata at DR site, which in most cases is cost-inhibitive. I would say that make sure you can do rolling upgrade for minimizing the downtime, and find a cost effective DR solution especially if you use HCC (Hybrid Columnar Compression).

The most valuable feature is definitely the performance. However, it's also a platform for both performance and consolidation. Once you start leveraging Exadata with Database In-Memory and Multitenant, you've got a really solid platform for database enterprise computing.

If you have server footprint reduction or consolidation as a requirement, then you can consolidate several databases and configurations onto one platform. Combine that with performance, it becomes a great avenue for cost reduction in terms of OpEx and CapEx. Exadata cannot be one-dimensional solution, performance, consolidation, and scalability must be part of the overall solution.

I think Oracle Enterprise Manager has come a long way with monitoring and managing Exadata, but getting the patching down would go a long way. I think the patching is still lacking quite a bit. If we can get the patching and upgrade in place, that would make a huge impact in overall supportability. I realize there is new OEM functionality recently introduced to support this, but it needs to be flushed out and tested.

It's been great. The stability has really, really improved a lot over the last couple of years.

It's been fantastic. With all the additional flash, with the faster CPUs, the faster disks, it's really come a long ways. The introduction of the X6 is also going to be an interesting avenue.

Tech support has been really good. That goes a long way because you have some comfort, stability in the fact that you've got somebody that you can lean on. You don't always have those skill sets. Since we're a services company, we do have those skill sets in that area, but most customers may not have that.

These guys are very well versed in the technology. They understand not only the storage software part of it, but the database as well as the hardware aspect of it -end to end. The most surprising aspect of Exadata is really the support.

It is quite difficult, but again since we're a services company, we're pretty well versed in it. We actually help customers do that end-to-end. Not only do we help bring Exadata in, we help do the installation and configuration and migration to the Exadata, as well as sustainability for future.

It takes a lot of planning depending on your downtime for conversion, depending where [platform] you're coming from. All those things play a big part in what tools you use and how you use them.

It is an expensive stack, so there's those things to keep in mind. The upside is that once you've bought into the technology, you have to embrace it , if that's the direction you want to go.

It is really good for what it's supposed to do. It's a great technology for Oracle-based solutions. There's pluses and minuses in everything. Any time you get an engineered system like that, you have to be geared for organizational [boundary] changes. Understand how the technology is supposed to work, how it's going to change the way you do your day-to-day business.

The most valuable feature would be Smart Scan because it gives us the ability to perform a large amount of processing on the storage side, cutting down on I/O tremendously. That's one of the big features that really drew us into jumping on Exadata.

We also like having the ability to have a lot of flash storage where a lot of our data can be in-memory, which speeds up transactions and processing.

As with any organization, before we embark on anything, we have to look at the ROI as well as the ability of a particular tool. Exadata helps us to consolidate and manage our databases as one with much faster processing. This, of course, is the key in speeding up our ability to do work and provide customer service. We're a mutual fund company, so speed is really key in providing satisfactory customer service. Exadata really gives us the key factors from an IT perspective, which are performance and availability.

There's a lot with Exadata that can be done on a black-box level which depends entirely on what the vendor is able to do for you, which is good from a certain perspective. But we hope, as this technology matures, Oracle allows customers to have a little more hands-on customization of some certain elements to better suit their environments. So we're looking forward to the ability to do greater customizations to suit our business needs.

Deployment wasn't difficult and we had no issues with it. Oracle had a bad rap in the past with customers who had bigger systems. They didn't provide them with enough assistance in order to assimilate new products and tools. But now, they've done a pretty good job of creating a very thorough cookbook, which has helped a lot with issues they we and my peers at other companies have had. Some of the issues was in the way we set up our enterprises which made it difficult to bring in and assimilate new products, but Oracle has lately done a good job of smoothing that out.

Exadata has been a very stable product once configured properly. We've had no issues with instability.

It's scaled to our needs.

We have premier-level technical support, so we have a pretty good relationship with them.

I would describe the initial setup as being of medium complexity. We're a financial insurance company, so we always want to put in a lot of rigor, in terms of security and compliance. At times, it's not our own fault, but it's our devices, but at the same time, the price of being exploited is bigger than what it takes to ensure security and compliance. The issue has been really more of the rigor that we put in ourselves, and finding a way to allow those new products and solutions to work as they were expected through our hardening that we've done on our environment.

We want to stay at the front of the cutting edge, and we evaluate and realize that the benefit, the return on investment that Exadata brings for a company of our magnitude and size, is tremendous. We've exploited Exadata, and it's performed very well for us.

The performance of Smart Scan, Storage Indexes, etc., and the High Availability features are all valuable to us.

We have a complete HA environment with two Exadata machines across two datacenters. We've able to use Data Guard to perform switchovers, perform maintenance, and do other tasks with little or no downtime at all.

The Lifecycle Management over the whole stack could be improved over what it already provides. The rolling upgrade feature on the database itself should be improved. It needs some Java updates as well as there is too much downtime related to Java issues.

I've been using the platform for five years, and my customer is now buying Exadata X5-2.

We didn't have an issue with deployment.

While we have am MAA environment, it is absolutely robust. We've had no issues with any instability.

There have been no issues scaling it for our needs.

Oracle Support Services should be improved. The customer has seen more and more discussions within the Oracle Support Groups indicating that support has done more and more finger-pointing, which doesn't help the customer to fix problems.

5/10 - They have a lot to improve upon.

There was no solution previously in place.

The initial setup was complex, but it was well planned by Oracle ACS.

We implemented it between Oracle ACS and an in-house team.

The pricing and licensing is really complex and you need to have a very detailed plan.

The customer looked at a Hitachi solution.

Start with a good POC and then make the decision.

• Smart Scan
• Smart Flash Cache
• High Availability
• Consolidation
• Robust Storage
• Computing

Because of Exadata Systems, we were able to consolidate all the applications databases into one, e.g, Oracle EBS, Siebel, Hyperion etc.

Exadata Linux systems have Intel CPUs inside. I would suggest that if Oracle could work together with Intel to have some more intelligence at the CPU level, then there would be nothing like it.

I've been using it since June 2013.

We didn't have any deployment issues.

After three to four months we may need to perform a rolling reboot of the DB/storage servers.

I would say it's the best solution in terms of scalability.

8/10.

9/10.

We used both EMC Storage and IBM Servers.

The setup was simple, however, the database migration was a bit challenging, but there was no show stopper anywhere.

We are a vendor TCS (Tata Consultancy Services) and have as a customer the Taj Group of Hotels (IHCL), where we deployed and implemented Exadata Systems.

It's almost 100%.

• IBM
• HP

Go for it if you are looking for consolidation/scalability.

The High Availability and rolling upgrade features are the most important for us. They help us achieve zero downtime and increased performance.

The biggest advantage to our implementation of Exadata is that because it's an Oracle-engineered system, our database administrations don't have to worry about performance tuning. It's already optimally tuned and, when compared to other systems, it's really provided us with better performance.

We've had no issues with deployment.

It is brand new for us, and we are slowly getting other databases into it. So far, it's good, but we are not using 100% of them, so we still have to learn a lot.

It has the best scalability of all our Oracle products.

We've created a lot of cases, so we're in touch with Oracle support frequently. The service is consistent across all our Oracle products because they're located in one place.

We previously used IBM InfoSphere Warehouse.

The initial setup was straightforward.

Oracle provided us with an on-site consultant to perform the installation.

We also looked at Microsoft SQL. We chose Exadata as we have other Oracle products, including Database.

If you are buying Exadata, be sure to go with the latest version.

• Smart Flash Cache
• Storage Index
• Smart Scan
• Hybrid Columnar Compression
• Oracle ASM
• Security with encryption
• Oracle platinum support

We were using a normal RAC on a Linux server for online applications and Oracle on the same platform for data warehousing. After moving to Oracle Exadata, we were able to add more users, and queries get executed very quickly for data warehousing, around one quarter to half the time when compared to our previous solution under normal conditions.

• Shared RAM for multiple instances
• Hardware update in terms of storage
• Ability to migrate a database to Exadata from a normal environment

I've been using it for five years, including in my previous company.

During migration, we approached transportable tablespace and Oracle database along with GoldenGate.

There have been no issues with stability.

It's been able to scale for our needs.

10/10 because we have Oracle Platinum Support.

Previously, we used SQL tuning, server tuning along with network tuning with huge storage and higher CPUs. It was a management decision, along with our recommendations, to move to Exadata.

It was a complex setup because we were implementing the online application as well as data warehousing on the same machine. Lots of planning took place before moving to Exadata, and we did regression testing for each application on an Oracle provided Exadata machine. After verification from our application team and management, we verified our test results.

We did it in-house with help from Oracle.

It's too costly.

I have seen, and it's my personal experience, that if your application runs on half a rack don't go for a full rack. After all, you can upgrade from half a rack to a full rack if needed, and there is no point to move directly onto a full rack.

Check with Oracle and do testing on the lower version rack first. Although sales people from Oracle will convince you to go for a higher version, which is not needed unless your design, architecture, and applications needed .
