HansThilen - PeerSpot reviewer
A highly scalable and astoundingly stable solution offering its users an extremely good technical support
Regarding an area to improve, I would say that from Dell EqualLogic family, I can't buy Dell EqualLogic PS series. I can't buy any more solutions provided by EqualLogic, so the solution will have to make certain improvements in the future. Since we can't buy anything from EqualLogic in our company, we plan to move to another solution. Since I can't buy it anymore, I don't receive any updates on the solution. Also, this is the last year in which one can buy support for the solution.

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.

Quotes from Members

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

Pros

"The product is very stable."
"We were attracted by the flexibility of being able to put in a new shelf whenever we needed to, to expand."
"The technical support for EqualLogic has been universally outstanding."
"It is extremely reliable."
"​It has contributed to the implementation of virtualization and all its benefits.​"
"The technical support for the solution was really good."
"The solution has been working well overall."
"You can always trust it. It is stable."
"I like its storage capacity, quick access to the data, speed, and overall storage management."
 

Cons

"The only challenging part in the tool was related to some site recovery area. In order to exploit the site recovery area, my company had to purchase additional VMware products."
"There is no inline deduplication capability."
"If I need to have more space or more capacity, I need to replace the product. It would be ideal if we could scale without replacing the box itself."
"I can't buy any more solutions provided by EqualLogic...Since I can't buy it anymore, I don't receive any updates on the solution. Also, this is the last year in which one can buy support for the solution."
"Why is it not possible for both controllers to be simultaneously active (load balancing)?"
"Dell EqualLogic PS series could improve the performance because in our hybrid configuration the read speed is faster than the write speed."
"The product is reaching the end-of-lifecycle."
"Synchronous replication uses space inefficiently."
"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."
 

Pricing and Cost Advice

"Licensing is pretty straightforward."
"Initial packages include all upgrades and services."
"Price-wise, the solution is cheap. I rate it a three on a scale of one to ten, where one is very cheap, and ten is very expensive."
"I didn't buy it. It was another person seven years ago. So, I don't really know, but all storage platforms cost a lot of money. It is probably in the mid-range, but you get what you pay for."
"​It is a fair price."
"Dell EqualLogic PS series can improve its scale-out feature. Sometimes the customer has a limited budget for storage expansion. When they want to expand their capacity, they need to buy a complete controller plus storage capacity, which sometimes is out of their budget. If Dell EqualLogic PS series support could scale up the environment in which only hard drive extension controllers should be supported, then customers can expand within a lower budget."
"There are annual maintenance costs beyond the original licensing period."
"It seemed expensive at first, but the durability lowered the cost of ownership dramatically over time."
"The price could be better. We have many competing products now like Huawei and Dell EMC, and these are slightly cheaper."
