Has enabled uninterrupted access to educational platforms and simplified storage management

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.

Quotes from Members

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

Pros

"We've dealt with technical support and have found them to be helpful and responsive."

"I have been using Equallogic arrays for myself and my customers for over seven years now, and they continue to be my gold standard for SMB storage."

"It is stable and scalable."

"The solution offers very good read capacities, the size of the box we have is pretty decent, the speed on offer is very good, we have found the initial setup to be fairly straightforward, and Dell's technical support is very good."

"The technical support is very good."

"It has contributed to the implementation of virtualization and all its benefits."

"Before deploying it, we used public clouds for our services, facing latency and other issues with other vendors; after deploying this cluster, we were very satisfied and relieved."

"If you have one datacenter fail, the VMs will start to run inside the other data center."

More Dell EqualLogic PS series pros

"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."

"The ability to create LUNs and modify them are the most valuable features of this solution."

"It's a mature product. It's like a BMW that evolves consistently."

"No queuing and high ops, speed, and performance."

"The stability is awesome, based off a mature product line that has been around since 1999, combining two well-known and well-proven technologies into a very solid solution."

"User friendly interface Robust hardware Good support"

"Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."

"Our automatic banking systems have become twice as quick with flash storage."

More IBM FlashSystem pros

Cons

"Dell EqualLogic PS series could improve by providing fiber channel connectivity. Fiber channel connectivity is not supported, which is a requirement of advanced applications, such as SAP HANA. SAP HANA recommends fiber channel connectivity, but the Dell EqualLogic PS series is only an ISCSI data storage."

"Why is it not possible for both controllers to be simultaneously active (load balancing)?"

"Synchronous replication uses space inefficiently."

"Three of the four devices have been rock solid, and one of them had a string of issues that we eventually resolved."

"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."

"Dell EqualLogic PS series could improve the performance because in our hybrid configuration the read speed is faster than the write speed."

"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."

"One problem with this solution is that synchronous replication requires lots of duplicated space."

More Dell EqualLogic PS series cons

"It doesn't scale out that well."

"This is an expensive solution compared to other similar solutions."

"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."

"The solution is quite expensive. That's one of the downsides to using it."

"The GUI needs some improvement."

"I don’t really have a feature that I’d be using."

"The stability of the solution isn't great; we have had a lot of issues with discs over the years."

"Cloud file sharing is an area that needs improvement."

More IBM FlashSystem cons

Pricing and Cost Advice

"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."

"All features are out of the box. The license will be in the virtual, OS, or application layer."

"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."

"There are annual maintenance costs beyond the original licensing period."

"It is a fair price."

"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."

"Initial packages include all upgrades and services."

"It seemed expensive at first, but the durability lowered the cost of ownership dramatically over time."

More Dell EqualLogic PS series pricing and cost advice

"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."

"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."

"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."

"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."

"I find the pricing of the solution to be very reasonable."

"The price is a little bit high so is rated a six out of ten."

"The tool is cost-efficient."

"Pricing can be considered as per market competition."
