Network Executive at Virtual University

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

"You can always trust it. It is stable."

"Enterprise features for snapshot management and replication benefited us greatly."

"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."

"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 scalability of the Dell EqualLogic PS series is very good, we had no issues."

"Dell EqualLogic PS series is a highly stable solution."

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

More Dell EqualLogic PS series pros

"The speed, performance, and stability are the best features of IBM FlashSystem."

"The most valuable features are deduplication and compression."

"This is probably the best unit you're going to find out there."

"IBM Storwize makes management of the IT environment much easier, with high availability and enhanced security, proven dependability, data compression with hardware acceleration, and advanced copy services features all in this product."

"IBM FlashSystem is flexible, quick, and has a solid design."

"This storage has incredible performance, the I/O is awesome."

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

"If you are looking for a great flash solution that can be virtualized or utilized as a building block for a scalable flash solution, or if you're looking for flash for a very specific workload, then you may want to consider a FlashSystem 900."

More IBM FlashSystem pros

Cons

"The price of any good iSCSI array is prohibitive for small businesses."

"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."

"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."

"Higher price at entry level systems compared to competition."

"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."

"The solution is out of date and the new version has a lot of advanced features."

"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."

More Dell EqualLogic PS series cons

"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."

"IBM should improve its data reduction development."

"The solution's pricing is a bit high so there is room for improvement."

"The GUI needs some improvement."

"It could be easier to implement."

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

"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."

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

More IBM FlashSystem cons

Pricing and Cost Advice

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

"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."

"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."

"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."

"Licensing is pretty straightforward."

More Dell EqualLogic PS series pricing and cost advice

"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."

"Our customers would like IMB FlashSystem to be less expensive."

"This solution is expensive compared to other solutions."

"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."

"The solution requires a license and could be less expensive."

"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."

"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
