What is our primary use case?
The primary use case for Dell PowerStore was for our disaster recovery site at our secondary data center.
The equipment there was already eight years old and we really needed to replace it. We couldn't get finance to back us with a big deployment and substantial funding. So we determined that we needed something that could run our critical tasks if our main data center goes offline.
While it's running particular tasks of secondary importance at that data center, it can also take the load of the critical systems that we're doing on daily backups and weekends' full backups.
What is most valuable?
The most valuable features of Dell PowerStore include the completion through or the integration with OpenManage, where it can communicate and send back critical alerts or issues from a storage standpoint, heating, cooling, and all the typical management aspects. That's a time saving. It's all under one window. I can look at the servers, I can look at the storage, and I can see if there are any alerts on anything if it's all green, versus having different management windows to go back and forth between.
I've realized cost savings from switching to Dell PowerStore from Nimble. There definitely has been cost savings since the integration and everything we're doing is easier on our internal time to manage.
I'm saving approximately 20% of time managing and running it, which is easier having it all under one access panel.
Going to all NVMe storage, the abilities for the access time and the latency with Dell PowerStore's all flash storage is fantastic. Before, we had spinning disk with front-ended SSD cache. Now we're all SSD, making it very fast.
We have some legacy apps, including our biggest ERP system that we're migrating from, which isn't even SQL server-based; it's a ProvideX database. We're considering a data warehouse and examining ETL options to get that data into a format that AI can analyze. Dell PowerStore and those PowerEdge servers have substantial capacity for that.
Dell PowerStore has features that specifically cater to the needs of our medium company. We're standardized with our network core at 10 gigs, however, they can go to 25 gigs. If we need changes, we're not ripping and replacing; we're simply changing some GBICs and fiber interfaces. Dell PowerStore itself can accommodate faster connections. I appreciate that we won't be forced into obsolescence within the first year.
One of the big performance metrics I use to measure success with Dell PowerStore is latency. The read and write latencies dropped significantly over our old system. With our Nimble storage, we had between 14 and 40 millisecond access times on some of our busier runs. Dell PowerStore rarely goes above five milliseconds. It's significantly faster, with most operations being sub-millisecond.
What needs improvement?
I understand the software-defined storage and other capabilities. That said, I still am a traditional person who considers block and file storage, and I need to double or triple it. What are my pathways for scaling or do I need to rip and replace with another product? So maybe some of the scalability issues are present with Dell PowerStore.
To make it a perfect 10, I would have wished the deployment staff had indicated this is the regular support line, yet offered to connect directly with support personnel to walk through the process. It would have been beneficial to have someone from the support team do a warm handoff to clarify who to contact for future assistance.
For how long have I used the solution?
It's still early to tell how Dell PowerStore has supported growth or operational success for our company since we've only had it in place for five months, having been implemented at the end of last year.
Going forward, as we replace additional equipment, we'll probably select Dell PowerStore again. We've been really happy with it and expect it to continue to provide good service for us in the future. Its manageability and feature set fit our company size really effectively.
What do I think about the stability of the solution?
In the five months we've been running Dell PowerStore, it's been 100% uptime with no issues at all, so it's been excellent.
What do I think about the scalability of the solution?
Scalability isn't necessarily our issue currently with Dell PowerStore, however, when adding substantial storage, it seems to require transitioning to other Dell products. Perhaps that's by design, moving into PowerFlex or other systems PowerScale.
Our initial deployment is 35 terabytes, and the dedupe, deduplication, and compression are all excellent. However, if we needed more capacity, it quickly moves out of Dell PowerStore into something else. If I needed something more, I would prefer to stay in the Dell PowerStore ecosystem.
How are customer service and support?
Based on our experience, I rate Dell's support overall as a nine out of ten.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
The primary reasons we switched to Dell PowerStore were that the reasons we originally selected Nimble seemed to be replaced or equivalent with Dell for cost per storage, features, functionality, and ease of use. With Dell PowerStore, we wanted to keep everything under one roof with Dell and not have vendors point fingers at each other.
When we have a support question with Nimble, they sometimes say it's the Dell server that's the problem. When we call Dell, they say it's the storage that's a problem. We wanted to eliminate that situation, so we brought in Dell PowerStore with the refresh of the PowerEdge servers.
How was the initial setup?
My experience with deploying Dell PowerStore has been really good. It's been great with no problems at all.
We also used the white glove install services where Dell would come in and we wrote out the worksheets of all the IP addresses, all the names, and everything, and Dell came on-site and configured everything for us. That was a great time saver; getting that up and running and fully deployed was a big help.
What was our ROI?
The return on investment since switching to Dell PowerStore has been really good.
The finance department didn't understand that our project was about $180,000 worth of equipment. I explained we're getting that on the leasing schedule or the Flex on Demand, bringing that in at $1,800 a month. They keep asking about the purchase price, however, I clarified that's what our monthly cost will be if our planned usage remains constant. If our usage increases, our monthly bill will increase. However, if our usage is what we expect, then we already know our costs for the next five years. In five years time, we can extend or replace it and get something different. The whole package turned out to be really good for us.
Which other solutions did I evaluate?
Before selecting Dell PowerStore, we considered staying with Nimble and just replacing it with the current solution. We also considered direct attached storage by putting more storage in and doing the vSAN type approach.
However, I always worry that with hyper-converged infrastructure, it's too many eggs in one basket. Despite having redundancy, I really prefer being able to have the storage in one basket, and the compute and the bare metal, the OS and guests in separate ones, so I can do maintenance on either of them separately. I still prefer that standalone separation between storage and compute.
What other advice do I have?
As the IT director, I helped select the process for managing and using Dell PowerStore. We replaced a Nimble iSCSI SAN with Dell PowerStore, and we're using Flex on Demand to minimize our costs. We also used a VAR to help us understand our costs and the equipment to basically avoid CapEx and turn it into just a monthly expense.
Everything worked effectively with Dell PowerStore. I have no reason not to rate it a ten out of ten.
