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

"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."

"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."

"The solution has been extremely consistent over the years, we've had absolutely no issues with the product at all, and it's lasted a long time without causing any problems."

"The technical support for EqualLogic has been universally outstanding."

"It has been extremely reliable and very easy to upgrade and expand."

"It is stable and scalable."

"The support was excellent."

"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."

More Dell EqualLogic PS series pros

"Virtualization of external storage, while adding cache and speed to the external storage."

"The pricing is reasonable."

"This solution is very stable."

"If someone wants a robust, scalable, and consistent behavior for their site, then they should use IBM FlashSystem."

"The compression and deduplication features are the most valuable."

"IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies."

"We are a 100% satisfied with the stability of the solution."

"The speed and the ease of installation are the most valuable features, and the IBM FlashSystem is the fastest in the industry."

More IBM FlashSystem pros

Cons

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

"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."

"Individual file recovery would be a nice additional feature."

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

"The solution is out of date and the new version has a lot of advanced features."

"The replication efficiency needs to be improved."

"There is no option for mixing RAID types in one device."

"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."

More Dell EqualLogic PS series cons

"The array level RAID does not seem available."

"The interface could improve in IBM FlashSystem."

"Support response times are bad."

"The solution is not easy to use and could improve."

"The GUI needs some improvement."

"I would like to see an improvement in the handling of large amounts of rights."

"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."

"I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that."

More IBM FlashSystem cons

Pricing and Cost Advice

"Licensing is pretty straightforward."

"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."

"Initial packages include all upgrades and services."

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

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

"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."

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

More Dell EqualLogic PS series pricing and cost advice

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."

"We have no issues with the price as it is very competitive."

"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."

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

"The price of IBM FlashSystem is reasonable."

"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."

"Its price is very good."

"You purchase it as a bundle and the price is comparable."
