Enterprise features for snapshot management and replication benefited us greatly, but performance and vision for the product were lacking

What is our primary use case?

We ran a large data housing solution that contained billions of data files.  We also used the product for VM storage and file server storage.

How has it helped my organization?

When initially purchased, it brought enterprise-class features to our systems. Very solid manageability and the product worked well with few technical or hardware issues. The performance was never very good, and its latency was higher than expected.

What is most valuable?

Enterprise features for snapshot management and replication benefited us greatly. The ability to quickly view and select from snapshots allowed us to restore data very quickly. Replication allowed us to move data from one data center to another with ease.

What needs improvement?

Performance and vision for the product were lacking.  DELL was taking on too many storage solutions, and it felt like the EqualLogic series was not aggressively supported.

High-availability, a lot of redundancy, good management software but it's entry-level SAN
Pros and Cons
  • "Its high availability. It has a lot of redundancy and good management software as well as good alerting."

    What is our primary use case?

    We use it for virtual machines and data. It performed well but it's end-of-life now. We have to refresh everything. It's still working but it's end of support for the product.

    How has it helped my organization?

    It did what it was supposed to do and it worked well. 

    What is most valuable?

    High availability. It has a lot of redundancy and good management software as well as good alerting.

    What needs improvement?

    Some of the new features include what they call auto-tiering, where data that needs to be on a faster storage, it would automatically detect that and move it to the faster storage or the most frequently accessed area. Data that doesn't move that much or is not accessed that often would go on a slower storage. It's more efficient, helps a company to maximize what they spend. This kind of storage costs a lot of money; they build that into the newer functionality and into newer SANs.

    If you are going to go with all-flash then it's very expensive but it has a lot of performance benefits and a lot of improvement in reliability. Some companies can afford leading edge. My company cannot afford leading edge, so we probably have to go one generation below.

    What do I think about the stability of the solution?

    It's very stable. We have had no issues.

    What do I think about the scalability of the solution?

    You have to determine your size as a company, if you're a small business, medium, or enterprise. The model that we bought was scaling to about a small- to medium-size business, but they give you enterprise functionality. That was the EqualLogic. But if we were bigger or we planned to grow or acquire, we probably would have selected Compellent or some other product line.

    You have to make sure you buy the right fit for you to scale because if you're a small company and you don't plan to expand, then this is a solution for you. If you plan to grow, then you need to buy a different model or different solution.

    The one that we're buying now is a unified storage solution. 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.

    At the end of the day, you have to remember that every three to five years you have to toss this equipment away and buy a new one. You don't want to overspend.

    How are customer service and technical support?

    The support was excellent. When there are alerts, they would get them and they would be on it right away, and they would send a technician to replace. If there was a hard drive that failed or controller that failed, they would send a technician. It was always up, never down. Very good support.

    Which solution did I use previously and why did I switch?

    We have alerts. Then the lifecycle refresh time came up, end-of-life. Now, you can continue getting support from a third-party who would support for 10 years after the end-of-life. What triggered us to make a change is the fact that we're running our production data on equipment that is no longer supported by the manufacturer.

    When selecting a vendor support is key, support and part-availability. The features, they are important too, but the most important thing to me and to us is the fact that, if there is a problem, the company will support you. Dell does an excellent job of support.

    We had HPE before. In my country, the local support vendor of HPE wasn't as diligent as Dell, but that may be different in another jurisdiction. I'm in the Bahamas, so if I was in America maybe I would have a different opinion.

    How was the initial setup?

    I was involved in the initial setup. It was straightforward.

    Which other solutions did I evaluate?

    The last five to seven years we went with Dell and they are a good vendor so we continued with them. The only difference is that EMC products have been acquired by Dell. 

    What other advice do I have?

    It's now end-of-life, end of support, so we're shopping around for a replacement. With all this technology, they only have a lifespan of three to five years and then new features and new functionality come along. New speed. The new ones perform at much faster speed, so you have to change everything often.

    I'd give the EqualLogic solution a seven out of 10. It is an entry-level SAN for the enterprise. We're a small business. The price point was good for us and it's scalable; we could buy as many modules as we need, as we grow. They work together. The management of it is good but it can't go higher than a seven because, like I say, it's entry-level. It doesn't have all the functionality and features of some of the more expensive ones. But again, based on the budgets we have to work with, it was the best we could afford.

    Gives us the flexibility to put in a new shelf whenever we need to expand
    Pros and Cons
    • "We were attracted by the flexibility of being able to put in a new shelf whenever we needed to, to expand."

      What is our primary use case?

      It is shared storage for VMware.

      How has it helped my organization?

      It was necessary to enable a lot of the advanced functions of VMware.

      What is most valuable?

      When we bought it, we were attracted by the flexibility of being able to put in a new shelf whenever we needed to, to expand.

      What needs improvement?

      They may already have a product, but I would be interested in either hybrid-flash or possibly an all-flash option.

      For how long have I used the solution?

      More than five years.

      What do I think about the stability of the solution?

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

      What do I think about the scalability of the solution?

      Scalability is pretty good.

      How are customer service and technical support?

      Technical support has been good to us.

      Which solution did I use previously and why did I switch?

      We used NetApp for a while, but we hated the interface. That is why we switched.

      When selecting a vendor, at this point I am looking for someone who can talk technical stuff with me, not just throw a storage number at me and then expect me to figure everything out.

      How was the initial setup?

      It was pretty straightforward. The first time around, we didn't completely understand how much space we were going to need for things like Snapshots and replication. So we didn't buy enough storage the first time.

      What's my experience with pricing, setup cost, and licensing?

      Licensing is pretty straightforward.

      What other advice do I have?

      I would give this solution an eight out of 10. It's pretty straightforward most of the time, and tech support is there when it's not straightforward. I'm giving them a knock for having had that string of hardware problems.

      The biggest hangup for us was knowing how much disk translates into how much actual space you have, when you're done doing the setup.

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

      How has it helped my organization?

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

      What is most valuable?

      • Reliability
      • Ease of implementation
      • Performance

      What needs improvement?

      1. Why is it not possible for both controllers to be simultaneously active (load balancing)?
      2. The searchable online documentation is missing.

      For how long have I used the solution?

      More than five years.

      What do I think about the stability of the solution?

      None.

      What do I think about the scalability of the solution?

      Not yet.

      How are customer service and technical support?

      I can't say as we have had no significant issues.

      Which solution did I use previously and why did I switch?

      No previous company. We migrated from a PS4110.

      How was the initial setup?

      Initial setup was straightforward. We had an EqualLogic course.

      What's my experience with pricing, setup cost, and licensing?

      It is a fair price.

      Which other solutions did I evaluate?

      We evaluated NetApp and EMC.

      What other advice do I have?

      Be sure the product is suitable, the warranty is guaranteed, and technically, use a disk (RAID) calculator for sizing.

      Among other things, ​block size, controllers, and failover mechanism for the controllers need improvement
      Pros and Cons
      • "If you have one datacenter fail, the VMs will start to run inside the other data center."
      • "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."

      What is most valuable?

      Synchronous replication. One group, one pool, one IP address, the member stands in two different datacenters with, for example, two hosts in DC1 and two hosts in DC2 in same ESX cluster. If you have one datacenter fail, the VMs will start to run inside the other data center.

      How has it helped my organization?

      EQL is pure block storage. EQL has not improved anything. It created a rigid change regime and bureaucracy after several firmware upgrade failures.

      What needs improvement?

      Block size, controllers, failover mechanism in general for the controllers. 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.

      For how long have I used the solution?

      Five years.

      What do I think about the stability of the solution?

      This product was very unstable in the beginning. A pool with more than one member could get crazy and start to empty one member to another member (if the pool went below 10% free capacity [from Dell], for real EQL processes started between 11-12% capacity). One member became full and crashed production which used the EQL pool.

      Fixed somewhere in v.6.1.x!? Two 6510es in pool generate, for example, 125TB. So we need 10% free capacity, 12.5TB in the pool to make sure EQL does not go crazy.

      What do I think about the scalability of the solution?

      Number of iSCSI connections. The EQL group has a maximum of four pools (at least in v.7xxx). You need at least one pool as a "maintenance" pool. In practical terms, we have only three useful pools in one group.

      How are customer service and technical support?

      Horrible. Very rarely do you meet people with a passion for the product. Meaning, how can people have passion for this product series?

      Which solution did I use previously and why did I switch?

      Started with 14x 6110x to run OS and regular data and some SQL. Filled up the IO long before capacity. Split up the groups and reformatted some of the EQLs to RAID 10 to run only the OS. That worked well. IO and storage capacity was quite even. Dell was very positive against snapshots. They forgot about their 15-16MB block size. Local snapshots on data stores which only run OS which generates 20% random reads and around 80% writes.

      Data retention was one snap each day in a seven day rotation. We got around 150% on the top of the datastore in only snapshot storage. EQL cheap? Hmmm... I don't think so.

      How was the initial setup?

      Straightforward.

      What's my experience with pricing, setup cost, and licensing?

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

      What other advice do I have?

      Do not go for EQL. It will be out of production in a few years. Dell EMC Unity is a much better option for price, performance, and safety.

      If you don't have alternatives, management should be fired! But seriously, you need to have very good control of your workload and IOPS. Which data cause random reads, sequential reads, random writes, sequential writes, etc. And you need to build your environment. The workload needs to be separated in VMs on different disks which touch different data stores and SAN environments.

      Our relationship with Dell EMC is very good. Dell has always been a good hardware vendor and are really good at it. They are also good in local storage in, for example, their MD series. Really good!

      They could not make the SAN part in EQL and Compellent. Maybe that was the reason Dell bought EMC.

      We are also using Dell F10 which provides quite good performance. Hardware is the same as Cisco, but there are some downs with their software. F10 doesn't have any control over some packages, such as pause frames. The switch will try to send those packages to all ports. So if you have activate flow control, you need to turn off RX or TX or the switch will flood all the ports with "unknown" packages.

      In the end. We will replace all EQLs with Dell EMC Unity. We have not upgraded EQL after 7.1.8, which is quite stable, because firmware upgrades cause us alot of trouble.

      Continues to be my gold standard for SMB storage

      Valuable Features:

      - Great performance for the price - Fantastic scalability via stackable scale-out units - Management interface is simple to use and understand - All tools and add-ons are included in the produce support, including future tooling releases - Support is always terrific - In seven+ years of using Equallogic, I have experienced ZERO unplanned outages on at least fifty arrays

      Room for Improvement:

      - The price of any good iSCSI array is prohibitive for small businesses - Higher price than other competitors in the same space, but the product is superior

      Other Advice:

      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. In my years of using these arrays, I continue to be impressed with their products, performance, configurations, and support.

      Dell Equallogic PS Storage System: a true virtualized iSCSI Storage Platform

      Valuable Features:

      a. A true virtualized storage system or enterprise storage system for capacity/data level virtualization. b. Performance increased with capacity if additional array included with existing deployment (Scale up architecture). c. Firmware compatibility across models and generations. Virtualization can be done with any generation and any feature model. d. All included application model. Need not to worry about application selection or pricing. Even if any new application/functionality included into PS Series platform in future that will also be entitled for current system.

      Room for Improvement:

      a. Only iSCSI interface. No choice for Fiber Channel connectivity. Have to select either 1G or 10G connecting iSCSI interfaces. b. Have to buy at pre-configured capacity models. Cannot buy 1 or 2 disks to increase existing capacity. c. Limitations to mix different types of disk (SSD, SATA, SAS) into same enclosure. d. Higher price at entry level systems compared to competition. For larger deployment price becomes more than competitive.

      Other Advice:

      a. Equallogic PS series arrays are the best suited storage platform for mid to high level enterprises. b. Cost of acquisition may seem to be higher but TCO is lower when compared for the high capacity deployments for virtualized environment. c. A very easy to use interfaces and easy to use wizard based configuration. d. PS Series comes with embedded 24x7 supports from Dell to ensure zero system downtime.
