A stable unified storage system that enables quick access to data

The main thing Oracle can improve is the cost. It would be better if Oracle opened up the system to enable integration with other vendors. Whether it's the database, application server, or storage appliance, they should make it easy to integrate them. They need to open up more to ensure that it can work in any environment and IT ecosystem.

The Nimble CS-Series has proven to be reliable with 100% uptime

When we started the process of looking for a SAN vendor I had four primary criteria: reliability, performance, cost, and simplicity. We were really looking for a unicorn and were fully expected to have to make compromises in one of those areas. The Nimble CS-Series was recommended by our solutions provider, and we were blown away. Not only was it the most affordable option, but it was the easiest to deploy, had the best performance, and has proven to be reliable with 100% uptime.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Very good analytics Very easy to configure."

"I like its storage capacity, quick access to the data, speed, and overall storage management."

"Oracle Sun ZFS Storage Appliance is a very stable and durable product that's very strong and mature."

"Stability has been rock solid, as we have been running both units for over two years with no major problems."

"If you are looking for a stable, powerful and effective entry level SAN that you can provision on your own for a small environment or a small office/remote office situation - this is definitely the product for you."

"It is very stable, even during multiple power failures."

"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."

"The replication feature provides another functionality to protect your data."

"Good performance for VM environments"

"I have worked on CLARiiON and all series of VNX."

"Since implementing VNX, we achieved a 10 times increase in the performance for its end users."

Cons

"The main thing Oracle can improve is the cost. It would be better if Oracle opened up the system to enable integration with other vendors. Whether it's the database, application server, or storage appliance, they should make it easy to integrate them. They need to open up more to ensure that it can work in any environment and IT ecosystem."

"Uptime. We had some crashes here and there."

"I do not recommend the Gen 1 VNX to anyone in this day and age."

"Customer Service: I don't like the way EMC's Powerlink support is behind a wall."

"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."

"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."

"EMC pricing is too expensive, like the Apple brand iPhone in the cellphone market."

"Oracle is never the cheaper solution. Compared to others, it is always among the most expensive."

"So far we haven't had many issues with the VNX. However, the Data Mover (that manages CIFS/NFS) part needs some improvements."

"Poor connection to FC."

Pricing and Cost Advice

"The price could be better. We have many competing products now like Huawei and Dell EMC, and these are slightly cheaper."

"Make sure you understand how the licensing works and that you are getting the right set of licenses if you need array-to-array replication."

"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."

"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."

"While EMC tends to be on the expensive side, the stability and support of their products are top-notch and I feel are worth the cost."

"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

"Reducing dependency on JavaServer Pages (JSP) could improve the administrative overhead."

"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
