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.

Cons

"The features provided for SMB customers are limited."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

"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."

"The feature that we're waiting on is better integration with the cell services."

"I have not seen ROI."

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

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

"Its configuration should be easier."

More Pure Storage FlashBlade cons

"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."

"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."

"Maybe it needs integration with HA."

"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."

"The solution's pricing could be better."

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

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

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

More IBM Spectrum Scale cons

"The performance is not as good as some competing products and reporting can be improved."

"I'd like to see improved hardware compatibility"

"There is room for more integrations and plugins into more storages."

"It doesn't have the ability to be deployed on any kind of hardware and network connectors."

"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."

"Simplifying the licensing model and making it cheaper would improve the solution."

"The license model of the product is an area of concern where improvements are required."

"VMware Software Defined Storage should include a shared database on a standard version."

Pricing and Cost Advice

"I feel that the price could always be lowered."

"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."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"Licensing fees are paid yearly."

"The product is very expensive."

"Our licensing is renewed annually."

"The price is a little high."

"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 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."

"The solution is very expensive."

"VMware Software Defined Storage is a slightly expensive solution."

"The product is quite expensive and is among the most expensive for this type of solution."

"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."

"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."

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.

IBM

VMware software-defined storage is a simple, yet intelligent, storage data center architecture that aligns with business and application demands—eliminating static, purpose-built and inefficient hardware with dynamic, agile and automated solutions.
