We use Dell EqualLogic PS Series as a secondary (mostly backups) device. The product seems to be completely abandoned by Dell (there is no Dell Virtual Storage manager for VMware vCenter 7.0+ and no recent firmware upgrades).
  • Snapshots
  • Replication
  • Performance is significantly lower than one would expect.
  • Support for VMware vVols is rudimentary.
While it is reliable, in my opinion, the performance is not so good. Additionally, the whole Dell EqualLogic PS Series seems to be abandoned by Dell in favor of other products (many of which they also abandoned since then). I would not recommend this product.
  • On the positive side, we managed to consolidate our storage and got sufficient capacity for our needs.
  • On a negative side, in my experience, there were many promises that Dell did not deliver (every time we wanted to use a specific feature that originally was mentioned as "coming soon" (e.g. compression or deduplication) we discovered that we would be forced to migrate to other models and invest a significant amount of money.
We picked Dell EqualLogic PS Series based on combination price/capacity/performance parameters. Unfortunately, in my opinion, not all of what we were promised came true.

We employ multiple Storage Area Networks (SANs) throughout our infrastructure, spanning various environments. Specifically, in our testing environment, the Dell EqualLogic PS Series server functions as our SAN solution. However, in our production environment, where we require over 100 TB of storage space, we faced limitations that prevented us from deploying this particular SAN due to space constraints.
  • Easy to configure
  • Simple ISCSI connectivity
  • Easy to provision LUNs and present it to ESXi
  • The Dell EqualLogic PS Series series I utilize is not capable of being upgraded to Fiber Channel
  • Given that all disks are SAS, the likelihood of disk failure during power issues is significant
  • Not many security features
Given its IO performance and bandwidth limitations, deploying this system in an enterprise-level setting would be impractical. However, it can effectively serve in non-production environments where demands are lower. Despite its unsuitability for heavy-duty tasks, the system offers valuable features such as straightforward configuration for data replication to its array partner. This replication capability enhances data backup processes, providing a reliable solution for safeguarding critical information in less demanding operational scenarios.
  • Few years back we experienced a severe power failure that resulted in multiple reboots of the storage system within a single day. When attempting to reconnect to the storage, we were confronted with the devastating discovery that the RAID configuration had been lost. To compound the issue, a staggering eight out of the twelve disks had been flagged as faulty. The situation quickly escalated into a nightmare as we embarked on the arduous task of recovering the critical data. It was a challenging and stressful ordeal, highlighting the importance of robust contingency plans and data backup strategies in mitigating such catastrophic events.
As the company initially operated on a smaller scale, we opted for Dell EqualLogic PS Series storage solutions, primarily because our data storage needs were modest. However, as the company expanded and demands grew, it became evident that the Dell EqualLogic PS Series system struggled to cope with the demands of enterprise-level applications. This instability posed significant challenges to our operations. Consequently, we made the strategic decision to relegate the EqualLogic storage to non-production environments. While it served adequately in smaller capacities, its limitations became increasingly apparent as our organization evolved, prompting the transition to more robust storage solutions better suited to our growing needs

We have multiple PS SANS across our organization in production and test environments. They serve as storage for a variety of physical and virtual nodes across our landscape. For an organization of our size, we needed heavyweight enterprise level storage, which could handle large Oracle databases, web servers, and general internal servers.
  • Provides a hybrid mixture of SAS and SSD disks
  • Different raid levels allowed across shelves
  • Daisy chain SAN controllers
  • One SAN controller failure can lead to big issues we unfortunately learned
  • Disks tend to fail quite frequently
  • The firmware upgrading process could do with an overhaul
If you need SAN storage at an enterprise level that can serve iSCSI and/or FC then EqualLogic shelves are a safe bet, especially as you can tier your storage for different speeds. We have a total of four PS Series units across the estate, all various sizes. However, we would recommend looking a Dell Compellents as well, as these are also excellent SANS for the enterprise.
  • Easy deployment with assistance from Dell meant a quick turn around time
  • Dell after support very good. Disk failures are dealt with quickly
  • Management of the units and ease
MD shelves which we also use, are a great, smaller alternative to SAN for backup solutions and small projects. The PS series and the Compellent shelves are powerful SAN units, with nothing between them really, apart from the pricing.

Dell EqualLogic PS Series is being used across our entire organization to store virtual servers and data. It allows our entire environment to run on one platform and gives us the ability to manage our data easily. More importantly, we are able to provision new servers and backup existing ones more efficiently.
  • iSCSI-based system that is quick to configure and set-up on the network.
  • Provisioning new LUNs and unified storage makes it straightforward to use with various systems.
  • Graphical interface is easy to use, allows for quick implementation of data pools and volumes.
  • Firmware issues sometimes hamper network connectivity across the network.
  • Pricing is more expensive than building your own network-attached storage.
  • Additional support costs for maintaining the latest software that the Dell EqualLogic runs on.
Dell EqualLogic is well suited in a virtual environment where the ability to quickly create new volumes is important. Also, being able to back-up and restore data pools is a key factor, as well as automating your storage environment. Smaller businesses would be less suited in this scenario and would be better off with a less expensive NAS solution.
  • The initial rollout of the Dell EqualLogic was quick and saved us time and money as a result.
  • Virtually zero downtime with the unit and redundant hardware is in place if an issue does arise.
  • Ability to scale the unit by purchasing larger drives, without having to purchase new hardware.
Having used HP StorageWorks, I have found that the Dell EqualLogic works more smoothly in a VMware environment. There are plugins that work in vSphere that allow you to create volumes and provision new virtual servers with relative ease. The software and interface that the EqualLogic runs on is more straightforward as well.

We use one PS series as our primary SAN for the whole organization for our virtual environment, and another PS series in our disaster recovery site. The primary replicates to the DR site.
  • Rock solid. A few hard drive failures over the years, but that is to be expected on a device that runs 24 hours a day.
  • Easy to configure and maintain
  • Solid redundancy. No single point of failure.
  • Be nice to use a hybrid of drives. Solid state and hard disk drives.
  • Configuration was easy, but the maintaining of it can be a little difficult. We are a small shop. The system runs great, but when it comes to increasing storage space, etc., it can be difficult because we aren't in it daily. Some options are buried pretty well, which makes it tough to find.
I find the PS Series is well suited for the small to mid-size organization. Larger organizations may need faster IOPS and 10Gb connections.
  • Great ROI. We have been using it for 5 years, with no downtime due to equipment failures.
  • Hewlett Packard
I think the PS Series stacked up equal to HP, for a lot less money.
