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.

Deliver improved performance in data processing and foster extensive AI initiatives

I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system. It achieved the best results when integrated with IBM hardware. Even though it is complex, it provided significant performance advantages in large-scale data management. Its fault tolerance mechanisms and integration capabilities make it popular for extensive AI initiatives and data processing tasks for organizations like Daimler Benz and Bosch.

Offers advanced features with notable emphasis on innovation

The best features of NetApp Cloud Volumes ONTAP include deduplication, compaction, and autonomous ransomware technology that native cloud storage solutions in AWS, Azure, or Google Cloud do not support. Moreover, NetApp Cloud Volumes ONTAP allows the use of multiple protocols including NFS, CIFS, and iSCSI, whereas native options may only support NFS and iSCSI. Customers already using on-premises NetApp storage such as FAS, AFF, or ASA can experience the same functionality on the cloud with NetApp Cloud Volumes ONTAP, which adds significant value. For data protection, customers can take advantage of the Snapshot technology available with NetApp Cloud Volumes ONTAP. This technology facilitates data recovery by allowing snapshots to be stored either on the same storage or on a disaster recovery (DR) storage. NetApp Cloud Volumes ONTAP helps us to take snapshots and store them on the same storage, with options for migration or replication of those snapshots to different storage, including on-premises DR storage or other cloud storage, providing excellent disaster recovery capabilities.

Quotes from Members

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

Pros

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

"The product is scalable and easy to expand."

"It's very easy-to-use."

"The initial setup is pretty quick."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"We can capacity plan at a greater level than we used to."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"The initial setup is pretty easy and simple."

More Pure Storage FlashBlade pros

"It is incredibly scalable and stable."

"Allows us to share files across multiple environments."

"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."

"I would rate my overall experience with IBM Spectrum Scale as nine out of ten."

"Technical support has been very helpful. They provide us with pretty good solutions that we can implement moving forward."

"GPFS monitoring is the best feature."

"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."

"Its great servicing high availability. That is what it is used for."

More IBM Spectrum Scale pros

"SnapMirror helps mirror metadata and data volumes between endpoints in a data fabric."

"They have very good support team who is very helpful. They will help you with every aspect of getting the deployment done."

"If you have a fair amount of experience with NetApp, you can work on it very easily."

"The fast recovery time objective with the ability to bring the environment back to production in case something happens."

"We're able to use the SnapMirror function and SnapMirror data from our on-prem environment into Azure. That is super-helpful. SnapMirror allows you to take data that exists on one NetApp, on a physical NetApp storage platform, and copy it over to another NetApp storage platform. It's a solid, proven technology, so we don't worry about whether data is getting lost or corrupted during the SnapMirror."

"So a lot of these licenses are at the rate that is required for capacity. So they're they're able to reduce the license consumption and also the consumption of the underlying cloud storage."

"Unified Manager, System Manager, and Cloud Manager are all GUI-based. It's easy for somebody who has not been exposed to this for years to pick it up and work with it."

"The FlexClones make all the management easier for us."

More NetApp Cloud Volumes ONTAP pros

Cons

"It's on the expensive side, as expected for a niche product."

"I want efficiency. FlashBlade doesn't have efficiency now."

"The features provided for SMB customers are limited."

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"The speed could be improved."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"I would like to see more deduplication."

"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."

More Pure Storage FlashBlade cons

"Integration with other vendors is not available."

"The solution's pricing could be better."

"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."

"There can be improvements in fault tolerance and making erasure coding faster."

"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."

"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."

"I believe there is no graphic user interface, so they should include it."

"This is probably the biggest challenge, getting everything upgraded, because it just takes time. We wish it was a faster solution to be able to do everything at once, but you have do each node individually. The more nodes, the longer it takes."

More IBM Spectrum Scale cons

"NetApp's support could improve"

"When it comes to a critical or a read-write-intensive application, it doesn't provide the performance that some applications require, especially for SAP. The SAP HANA database has a write-latency of less than 2 milliseconds and the CVO solution does not fit there. It could be used for other databases, where the requirements are not so demanding, especially when it comes to write-latency."

"The product is more restricted with underlying cloud."

"How it handles erasure coding. I feel it the improvement should be there. Basically, it should be seamless. You don't want to have an underlying hardware issue or something, then suddenly there's no reads or writes. Luckily, it's at a replication site, so our main production site is still working and writing to it. But, the replication site has stopped right now while we try to bring that node back. Since we implemented in bare-metal, not in appliance, we had to go back to the original vendor. They didn't send it in time, and we had a hardware memory issue. Then, we had a hard disk issue, which brought the node down physically."

"The navigation on some of the configuration parameters is a bit cumbersome, making the learning curve on functions somewhat steep."

"In the next release, I would like to see more options on the dashboard."

"Multipathing for iSCSI LUNs is difficult to deal with from the client-side and I'd love to see a single entry point that can be moved around within the cluster to simplify the client configuration."

"The key feature, that we'd like to see in that is the ability to sync between regions within the AWS and Azure regions. We could use the cloud sync service, but we'd really like that native functionality within the cloud volume service."

More NetApp Cloud Volumes ONTAP cons

Pricing and Cost Advice

"The pricing for FlashBlade is between cheap and moderate."

"Licensing fees are paid yearly."

"Our licensing is renewed annually."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"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."

"The price could be cheaper."

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

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

More Pure Storage FlashBlade pricing and cost advice

"The licensing is based on the number of terabytes."

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."

"The solution is costly but reliable."

"I know the licensing is a bit on the high-end. That's when we had to downsize our MetroCluster disks and just migrate to disks that were half used. We migrated into those just to reduce maintenance costs."

"The standard pricing is online. Pricing depends. If you're using the PayGo model, then it's just the normal costs on the Microsoft page. If you're using Bring Your Own License, which is what we're doing, then you get with your sales contact at NetApp and start figuring out what price is the best, in the end, for your company."

"Our licensing costs are folded into the hardware purchases and I have never differentiated between the two."

"For enterprise customers, it's a very cost effective. But in the SMB segment, yeah, pricing is a little bit challenge for your time."

"They allow a special price if you are working closely with them. Since we have a lot of NetApp systems, we got some kind of discount. That's something they do for other customers, not just for us. The price was fair. In addition to the licensing fees, you're paying Amazon for your usage..."

"It is not a cheap solution because we need to pay for the license and pay for Azure resources as well."

"Overall, the pricing of NetApp is aggressive and the pricing becomes more aggressive as the amount of data increases. The cost for a given volume of data that you are storing becomes lower. The greater the volume of data, the cheaper the license."

"It is expensive. There are no costs in addition to their standard licensing fees."

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

IBM Spectrum Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.
