Senior Network Engineer at Holy Redeemer Health System, Inc.

High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

Manages large data sets efficiently with hybrid cloud integration

My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.

Offers the ease with which you can move data between on-premises storage and the cloud and then retrieve it back on-premises when necessary

IBM Cloud Object Storage supports big data and analytics workflows. However, I usually have to refer to my documentation for that. Cloud environments are part of almost every project I've been involved in over the last few years, but I rely heavily on documentation whenever I need to do anything in the cloud. I know the basics, but the technical details always need refreshing. I create the drawings or diagrams of how the on-premises and cloud environments interact. So, visual representations are helpful. I'll diagram the on-premises environment, the cloud environment, and any appliances in between and then work from there. The integration capabilities simplified our data workflows. Like, the integration itself is pretty easy. The access appliances create the connection between both environments.

Quotes from Members

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

Pros

"We have seen a reduction in the total cost of ownership by around 20%."

"The initial setup is pretty quick."

"Using this solution has made our backups more reliable."

"The product is scalable and easy to expand."

"The solution provides many controllers."

"It is very easy to use, and it is very fast."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

More Pure Storage FlashBlade pros

"There are also the policies that you set up on replication and purging files, and policies for something called WORM. That's a "write once, read many," where you can't overwrite certain files or certain data. It puts them in a "protected mode" where it becomes very difficult for someone to accidentally delete. We use that for certain files or certain directories, because we're dealing with video and some video has to be protected for chain-of-custody purposes. The WORM feature works great."

"You plug in a new node and data starts migrating over to it, and IT spreads out the load. We've added multiple nodes to the system since deploying it. The process is pretty seamless, and we are able to do it with no downtime. It's a very easy process to do."

"The solution is extremely easy to manage. This is its most valuable feature."

"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."

"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."

"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."

"The solution's most valuable features are scalability and flexibility."

"The solution allows me to use SSMDS to store data for end users and share it within different locations."

More Dell PowerScale (Isilon) pros

"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."

"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."

"IBM Cloud Object Storage integrates well."

"The integration itself is pretty easy. The access appliances create the connection between both environments."

"Overall, I rate IBM Cloud Object Storage a ten out of ten."

"One of Cloud Object Storage's best features is infinite capacity. This is one of the main advantages if you don't want to use your own storage. You also have the ability to write only, write once, and read many. It's like tape storage but software-based. This feature is essential for financial institutions that require that kind of protection if you write backup or data there."

"IBM has the most number of additional services, this is the main advantage."

"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."

Cons

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"The features provided for SMB customers are limited."

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"Pure Storage FlashBlade should improve on more cloud integration."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"I would like to see more monitoring capability included in the next release of this solution."

More Pure Storage FlashBlade cons

"If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened."

"Some improvements to the NFS support would be of interest to us."

"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."

"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."

"The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage."

"The analytics could be improved."

"Dell's customer service needs improvement."

"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."

More Dell PowerScale (Isilon) cons

"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."

"IBM Cloud storage is not cheap, but it could be."

"If I had to choose one area, it would be making the consoles more intuitive would be helpful. Sometimes, they can be a little complicated if you're not familiar with them."

"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."

"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."

"Room for improvement depends on customer needs. Some customers prefer pure Object Storage using the S3 protocol, while others use a gateway in front of the storage grid to enable CIFS or NFS."

"The performance could be better. It isn't bad, but everything is network-based, so you have a performance penalty on the network. You can never achieve the same performance as hardware. That's the disadvantage of cloud storage solutions in general. Cloud performance is one of the main issues clients have."

"IBM has limited cloud storage."

More IBM Cloud Object Storage cons

Pricing and Cost Advice

"The price is a little high."

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"We used a reseller for the purchase."

"Licensing fees are paid yearly."

"Our licensing is renewed annually."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"The price of this solution could be made more affordable."

More Pure Storage FlashBlade pricing and cost advice

"It is an expensive product with a high storage capacity suitable for large data requirements."

"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."

"The pricing for this solution is reasonable."

"The price of the solution is high."

"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."

"It is a really expensive solution."

"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."

More Dell PowerScale (Isilon) pricing and cost advice

"Like most cloud providers, IBM likely charges based on storage capacity, typically per gigabyte or terabyte. Their pricing is competitive when compared to AWS or Microsoft."

"Pricing is not cheap."

"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."

"You have the option of a monthly or yearly license. Most customers choose the monthly option. I understand what you would like to say. IBM also lets you choose among four types of Cloud Object Storage. The difference is usage, performance, etc. Of course, high-performance storage is more expensive, while low-performance storage is for cold data, and it's really cheap."
