Eric Black

Solutions Architect at Recovery Point Systems

The ability to leverage multi-tenancy along with immutability is a huge benefit for us

The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

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

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

"I would rate Pure Storage FlashBlade a ten out of ten."

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

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

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

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

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

More Pure Storage FlashBlade pros

"We can have multiple systems within the same file system."

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

"The profile share is a valuable feature."

"GPFS monitoring is the best feature."

"We are using it for monitoring all of our storage."

"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."

"It is a scalable solution."

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

More IBM Spectrum Scale pros

"Its scalability is very good."

"Replication to the cloud is the most valuable feature. Deduplication and compression are also very important to us. We are in the process of adopting to the cloud. We are going to AWS and we are trying to do a safety technician call out with integration to the cloud. NetApp allows us to move some of the volume to the cloud, at the same time that we continue providing the cloud services that we have on premises."

"Its functionality and technical support are adequate to help prevent failure due to errors."

"This solution has made everything easier to do."

"The good thing about NetApp is the features that are available on the cloud are also available on-premises."

"One of the features our customers like is that it can be used from one cloud provider to another. They can use it from Azure to AWS or vice versa. That way, they don't need to use the same provider for backups. If something goes wrong on the primary site, having the same data in another cloud service provider is important."

"If anything happens, their technical support will come onsite and fix it."

"NetApp's Integration with AWS has helped us because we had a tough time transferring data when we used an ONTAP competitor as our storage partner. They don't have integration with AWS tools, so we had to figure it out on our own. ONTAP has built-in integration and allows us to replicate a copy to our second data center."

Cons

"It would be nice if you could store file-based in the same box with the same technology."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

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

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

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

"I would like to see the licensing fees improved as well as the price per terabytes."

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

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

More Pure Storage FlashBlade cons

"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."

"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."

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

"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."

"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."

"Maybe it needs integration with HA."

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

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

More IBM Spectrum Scale cons

"The automated deployment was a bit complex using the public APIs. When we had to deploy Cloud Volumes ONTAP on a regular basis using automation, It could be a bit of a challenge."

"I would like this solution to be brought to all the three major players. Right now it's supported only on AWS and Azure. They should bring it to Google as well, because we would like to have flexibility in choosing the underlying cloud storage provider."

"NetApp Cloud Volumes ONTAP should improve its support."

"If they could include clustering together multiple physical Cloud Volumes ONTAP devices as an option, that could be helpful."

"I would like some more performance matrices to know what it is doing. It has some matrices inherent to the Cloud Volumes ONTAP. But inside Cloud Manager, it would also be nice to see. You can have a little Snapshot, then drill down if you go a little deeper."

"The DR has room for improvement. For example, we now have NetApp in Western Europe and we would like to back up the information to another region. It's impossible. We need to bring up an additional NetApp in that other region and create a Cloud Manager automation to copy the data... I would prefer it to be a more integrated solution like it was in the NetApp solution about a year ago. I would like to see something like AltaVault but in the cloud."

"In terms of improvement, I would like to see the Azure NetApp Files have the capability of doing SnapMirrors. Azure NetApp Files is, as we know, is an AFF system and it's not used in any of the Microsoft resources. It's basically NetApp hardware, so the best performance you can achieve, but the only reason we can't use that right now is because of the region that it's available in. The second was the SnapMirror capability that we didn't have that we heavily rely on right now."

"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

"Our licensing is renewed annually."

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

"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."

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

"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."

"The product is very expensive."

"We used a reseller for the purchase."

More Pure Storage FlashBlade pricing and cost advice

"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."

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

"Once we deploy the pay as you go model, we cannot convert this product as a BYOL model. This is a concern that we have."

"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."

"Purchasing through the AWS Marketplace was good, but it was a test system, not a real purchase."

"If we wanted to use the AWS solution, we would have to manage two or three different platforms and pay more money than what we should have to pay, as some of the features don't even exist. If we wanted to, we could use AWS cloning, but it is useless because it uses more space, is more expensive, and takes more time."

"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."

"For NetApp it's about $20,000 for a single node and $30,000 for the HA."

"They give us a good price for CVO licenses. It is one of the reasons that we went with the product."

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.
