What is our primary use case?
Someone approached me to get a review of my experience with Dell PowerVault. I have used Dell PowerVault servers on multiple sites, and recently, those were customer sites. I work for one organization that had some customers, so I have worked directly with the hardware, from the starting configuration to the basic cable connection, configuration, and then connectivity.
I am an engineer. I work for different customers, whatever the project comes to me, rather than being a customer of this solution or an integrator, reseller, or consultant.
I mostly work with the storage part of Dell PowerVault. There were the primary servers and there was a 4012 expansion or storage expansion, or I think 512. I do not actually remember the model.
I mostly use it as a storage solution. I have worked with some Dell stand-alone servers, but for Dell PowerVault, I have used the storage part.
What is most valuable?
The first aspect of Dell PowerVault that I like is that it is easy to configure. It is available in GUI, so you can easily configure and change the settings as required. Another feature I appreciate is that it provides two controllers, which need to be configured for redundancy. If you lose one controller or there is any hardware failure, the other controller will take over. It keeps going on, and you can always do thick hardening or thin hardening. You can create pools and LUNs inside it. Many features are available inside it, and you can easily do it.
Dell PowerVault provides a streamlined workflow for me and my customers. I have worked on hundreds of projects right now, and they either opt for Dell or HP, who are the top competitors in the market. Out of 100, about 60-70 sites have Dell hardware only, which is what solution architecture even recommends.
What needs improvement?
I had one issue with managing comprehensive storage data management features such as snapshot, replication, and provisioning with Dell PowerVault. Once you create the LUNs, you can always expand the storage, but you cannot really reduce it. Sometimes, engineers or someone who does not have proper knowledge always give more storage than what is required initially, and then we cannot reduce that storage. That particular storage LUN gets wasted, which is something I am always negative about because we cannot reduce any size of LUN. The only option is to expand it.
In addition to being unable to reduce the storage, I believe the setup of Dell PowerVault, such as the main primary server and expansion, needs improvement. When you have a power failure or you lose your expansion or primary server, it seems to get corrupted easily. It was supposed to be that you have to first shut down the expansion and then the primary server. However, in hardware failure cases, if your primary server goes down before the expansion, sometimes there is a risk of getting the storage corrupted. If there could be a controller inside it that can manually shut down in the case of UPS for a minute, it would make a significant difference.
I would appreciate more advanced management of expansion because, in the case of UPS, you have one main power supply and then a UPS power supply. You get enough time to shut down the servers if there is a particular power failure.
For how long have I used the solution?
I have been using Dell PowerVault for more than two years.
What do I think about the stability of the solution?
I would say the stability and reliability of Dell PowerVault are good because for the last two years, I have not faced any failure—not a single failure.
Outages do happen, but I would say that is majorly because of the data center where it is installed in the rack, not the actual server or Dell PowerVault itself. Maybe the temperature is rising and they are not able to keep it cool enough or there is any cable fault in that particular data center. Other than that, I have never faced a scenario where the reason for any outage was Dell PowerVault.
What do I think about the scalability of the solution?
The only complexity I found in the initial setup process I was involved in was the cable connection for Dell PowerVault. It is not mentioned anywhere how to connect it. We faced some issues with the connectivity. For example, I have three physical servers and only one storage expansion, and I have multiple physical servers that need access to that single shared storage. For that kind of architecture, we faced an issue because I think it is mostly supported for a maximum of three physical servers; you cannot connect more than that.
I would appreciate Dell improving the scalability of Dell PowerVault. I think four or five is enough; if you can scale it to up to five physical server connections, it will be more helpful. Then they can increase the storage size in the single hardware, and we do not have to purchase another expansion for it.
How are customer service and support?
I am not often communicating with the technical support of Dell PowerVault; there is a middleman who actually purchases the server, and he is the one who connects it. I only share logs from the server.
I do use official documentation, guides, or manuals that Dell provides for Dell PowerVault. Whenever we raise any ticket or case with them, they communicate via email and share what they need or ask us to check for initial troubleshooting or logs. They share steps or a link to follow and tell us over the email.
I think the amount of documentation I have is enough for now, but I do face an issue only with the response time. Sometimes they take days to respond back.
Which solution did I use previously and why did I switch?
Before Dell PowerVault, we were using HP ones with the HP vendors.
How was the initial setup?
I did participate in the initial setup of Dell PowerVault. Even when it gets delivered, we are the ones who unbox it, and I am involved from the unboxing to cable connection, and then configuring it for the first time by providing the management IP to access it virtually from anywhere.
What about the implementation team?
I have not used the HTML5 PowerVault Manager GUI for ME5. I do not use the terminal mostly because I think the GUI is easier and more accessible.
I only use the actual management IP we configure with it, not the HTML5 PowerVault Manager GUI for ME5.
I have not utilized the bi-directional asynchronous replication feature of ME5.
What was our ROI?
Dell PowerVault has definitely helped streamline workflows for me and my customers. I have worked on hundreds of projects right now, and they either opt for Dell or HP, who are the top competitors in the market. Out of 100, about 60-70 sites have Dell hardware only, which is what solution architecture even recommends.
What's my experience with pricing, setup cost, and licensing?
Budget is one concept I am not aware of because I am not really involved in it, so I cannot comment on whether Dell PowerVault has contributed to staying within budget for operations.
Which other solutions did I evaluate?
I think the reason I decided to switch from HP to Dell PowerVault is that even today, I am working with one of the Dell NAS, 1FS something. It is easier to manage, and I would say it is very GUI friendly. Your configuration is easier, and you can make more changes. Other vendors are very hardcore, and you have to involve a vendor every time, but with Dell, engineers can manage things by themselves without needing to include the vendor repeatedly for making changes.
What other advice do I have?
We do use on-demand and scheduled snapshots with Dell PowerVault at the start of the projects, but we are not using it once we hand over the project. Once we go live with productions, we are not, because I work as an implementation engineer. I am not there for the full life of something such as a 10-year project, so I am not there to manage all of this.
I am not sure about any impact of these capabilities on data management strategy. I cannot recall any sample or any case right now. We can create different types of LUNs according to our use, and we were able to manage whatever our goal was with Dell PowerVault, but I do not really recall any specific case.
I would rate this review 9 out of 10.
