Offers good stability and simplicity

The room for improvement lies in the responsiveness and real-time feedback of the web server setup. We could set up the installation through a web server, but it's not very reactive on the web server. For example, when you launch a task, and you don't know exactly if the task has begun or if the task is in progress, or if it's finished. You have to wait for three to five to ten minutes to be sure that the task is running or in progress or finished. So at that point, it's not very good. For the rest, we have a good organization for the platform. And it's working everywhere. Another area of improvement is duplication.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable feature of Dell PowerVault is its ability to provide small to medium-range storage. It doesn't have any specific standout features, but it's great for applications, such as surveillance where a large number of videos need to be recorded and performance isn't a priority."

"The most valuable features are that it's easy to set up PowerVault. I also like the provisioning of storage."

"Dell PowerVault is cheap."

"The initial setup was easy and simple."

"The most valuable feature of this solution is that it is easy to manage and easy to use."

"Stability-wise, I rate the solution a ten out of ten."

"It is an inexpensive storage solution."

"Dell PowerVault offers valuable full flash storage."

More Dell PowerVault pros

"Based on customer feedback, I rate it highly as one of the most stable products in the backup and archiving line compared to offerings like Data Domain or from Huawei and Lenovo."

"HPE StoreOnce is particularly useful in situations where organizations require a backup solution to store their data. Its deduplication feature is quite impressive, providing a deduplication ratio of around 25 to 26."

"Currently, VTLs can only be created on individual service sets and cannot be used to share the resources of other nodes."

"Recovery is important."

"HPE StoreOnce works well, it is stable."

"Has very good deduplication and encryption features."

"The solution saves a lot of storage capacity."

"The most valuable feature of the solution is that the tool provides good value for somebody who needs an affordable and reliable storage solution."

More HPE StoreOnce pros

Cons

"If the solution came with a synchronous application, it would be particularly advantageous for small businesses operating across multiple sites."

"Sometimes integrating into a cluster can be difficult as you have to do it manually."

"There have been situations when our customers requested professional support and the price of that feature is quite high."

"If you do not have an existing relationship with Dell or are exploring the market for the first time, the initial acquisition cost of Dell PowerVault is high compared to competitors such as Hitachi or IBM, which often undercut prices."

"In the next release, I would like the deduplication and compression included, as well as the flash technology. It doesn't currently use it."

"In most instances, clients are using Dell PowerVault with tape drives, but we want to transition them away from tape drives due to the risk of data loss."

"Dell PowerVault could improve by having a higher cache and file protocol support added."

"I would like Dell to improve on the configuration of the disk groups. Only one group is expandable. Once you configure the other disk group types, you cannot expand them. It limits scalability. If you want maybe to grow a disk group, you lose information, and then you need to build it up again, which is not a good use case for customers."

More Dell PowerVault cons

"They could provide more options for storage capacity."

"The setup phase is not so simple that an end user can plug and play to make it operational."

"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."

"The solution would be improved if it could also be used as a data store for VMware."

"The solution should continue to refine its integration capabilities. I also see they are starting to use cloud integration as well, which is good, but they should do more to integrate with it."

"When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later."

"We're outsourced with a partner who recalls a larger amount of problems with the stability of the product."

"The user interface of HPE StoreOnce is an area of concern where improvements are required."

Pricing and Cost Advice

"Dell PowerVault's price is the tool's main attraction."

"They are offering a wide range of support models for the customers such as basic support that is budget-friendly, but they also provide a professional support solution that is a bit costly"

"The solution is more cost-effective than the competitors. It’s an affordable option for small businesses."

"The cost, compared to other solutions, is on the higher end."

"I rate the solution's pricing a seven to eight out of ten."

"I rate Dell PowerVault a six or seven out of ten for pricing."

"The product is inexpensive."

"The price of Dell PowerVault could be reduced. It is more expensive than some IBM solutions."

More Dell PowerVault pricing and cost advice

"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."

"To be honest, we were quite happy with the price, but we always want things cheaper than they are. I think for what we got, we felt that the price was quite reasonable comparing it to other products that provide that same level of functionality."

"Price-wise, it comes with a high price tag when compared to other products."

"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."

"We have got a perpetual license, and we have access to all the features. If you are using cloud banks, you can store the internal data in HPE Cloud if needed. You can offload the data to the HPE Cloud. It is a licensed product. We have got around 10 TB of cloud bank storage with a one-time payment. We specifically took 10 TB for very critical offsite backups. We can also increase it in blocks if needed."

"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."

"The solution is pretty expensive."

"The solution's cost is above average."
