Dell EqualLogic PS series is easily scalable, and we can add extra boxes and storage. It was easy to deploy during COVID. Deploying Dell EqualLogic PS series is straightforward, with no complexity involved. Dell EqualLogic PS series is a good product. We did not experience any failures in the last six to seven years, and it is still running as our storage for offline data. There are snapshot capabilities in data protection available, but we did not use that feature because it consumes much space. We have only 150 terabytes of space and simply use it to create volumes without utilizing it for snapshots. We use thin provisioning in Dell EqualLogic PS series, but I did not explore that feature further.

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 technical support for EqualLogic has been universally outstanding."
"If you have one datacenter fail, the VMs will start to run inside the other data center."
"If you have one datacenter fail, the VMs will start to run inside the other data center."
"Enterprise features for snapshot management and replication benefited us greatly."
"I am satisfied with it; it works very fine for our purpose, and its performance is enough for our needs."
"The support was excellent."
"Technical support, when we had access to it, was very good."
"Equallogic PS series arrays are the best suited storage platform for mid to high level enterprises."
"I like its storage capacity, quick access to the data, speed, and overall storage management."
"Very good analytics Very easy to configure."
"Oracle Sun ZFS Storage Appliance is a very stable and durable product that's very strong and mature."
 

Cons

"Three of the four devices have been rock solid, and one of them had a string of issues that we eventually resolved."
"Dell EqualLogic PS series could improve the performance because in our hybrid configuration the read speed is faster than the write speed."
"Higher price at entry level systems compared to competition."
"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."
"It's kind of expensive when you buy the EqualLogic solution because, as you grow, you have to keep buying another controller. It can be more expensive with time."
"When they deployed our cluster, they did not provide any documentation or low-level or high-level diagrams. They simply came, mounted the servers, and started installation without documentation, which is a negative point on the vendor side."
"It is at the end of support and no longer supported. We have to move our VMware to another storage platform, and we have decided to use Dell PowerStore. We like Dell's products, and it is a new platform with a lot of features."
"6510 and 6610 have two iSCSI connections in each controller. Why do 6110xxx members have only one, and why do the same members have the possibility of having an active iSCSI interface in the passive controller? It could make a lot of noise with a failover."
"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."
"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."
 

Pricing and Cost Advice

"I don't think I would say that the product is less expensive...The product's price is not an issue for our company, considering the relationship we have with Dell and the customer support we receive."
"Initial packages include all upgrades and services."
"All features are out of the box. The license will be in the virtual, OS, or application layer."
"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."
"​It is a fair price."
"There are annual maintenance costs beyond the original licensing period."
"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."
"Licensing is pretty straightforward."
"The price could be better. We have many competing products now like Huawei and Dell EMC, and these are slightly cheaper."
