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.

Quotes from Members

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

Pros

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

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

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

"The most valuable features of this solution are the rewrite speed and the nonstop services."

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

"The most valuable feature is Safe Mode."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

More Pure Storage FlashBlade pros

"Its technical support is excellent."

"The initial setup is straightforward."

"It's mainly about the storage expansion, like in hyper-converged solutions."

"The most valuable feature is that there is no single point of failure."

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

"The most valuable feature are the caching capabilities using the storage class memory."

"The performance, reliability, and affordability has been most valuable."

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

More Microsoft Storage Spaces Direct pros

"It is a stable solution."

"The solution made our backups way more reliable."

"StarWind VTL allowed us to back up to virtual tape that was created within Veeam and upload the tape to the cloud."

"The most valuable feature of the StarWind Virtual Tape Library is the archiving to the AWS cloud."

"I like the fact that we can simultaneously upload the virtual tapes to different cloud providers, and the settings can be adjusted to speed up the upload times even further."

Cons

"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."

"They need better integration with public clouds along with a better hybrid solution."

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

"The features provided for SMB customers are limited."

"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."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"The documentational aspect of FlashBlade needs improvement."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

More Pure Storage FlashBlade cons

"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."

"I think the online documentation needs a lot of work and so do the sizing tools."

"Microsoft closed the shared cluster support, which is important for the solution."

"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."

"Documentation management could be improved"

"It is difficult to get a hardware compatibility certification for the solution."

"More optimization could be done in terms of mirroring."

More Microsoft Storage Spaces Direct cons

"The main thing that I felt could be improved was having an estimated time of completion for the virtual tape uploads to the cloud."

"The initial installation can be complex and should be simplified."

"The solution's training process and online documentation could be more thorough."

"I am not sure if this is a limitation of my physical hardware or if it is the software itself. However, I would like the throughput to be faster."

Pricing and Cost Advice

"The price could be cheaper."

"I understand that it is competitively priced compared to other brands."

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

"We used a reseller for the purchase."

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

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

"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."

More Pure Storage FlashBlade pricing and cost advice

"With the data center licensing and everything that is connected to that, this solution is relatively costly."

"Cost-wise the product is one of the more affordable within the category of products."

"The solution is expensive."

"The pricing of the solution could be more flexible to meet the needs of smaller to mid-market size companies."

"The solution is cost-effective."

"The initial setup and deployment are also covered in the purchase at no additional cost."

"If you currently have Veeam there is no other solution that is as easy and affordable as StarWind."

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

Storage Spaces Direct uses industry-standard servers with local-attached drives to create highly available, highly scalable software-defined storage at a fraction of the cost of traditional SAN or NAS arrays. Its converged or hyper-converged architecture radically simplifies procurement and deployment, while features like caching, storage tiers, and erasure coding, together with the latest hardware innovation like RDMA networking and NVMe drives, deliver unrivaled efficiency and performance.

Microsoft

For SMB and Enterprises, who either look to get rid of backup tapes completely, or are willing to accelerate backup process and add an extra level of protection, our solution is StarWind Virtual Tape Library (VTL). It is an appliance that eliminates the need in physical tape and “pretends” to be a supported tape drive or autoloader, keeping all data on inexpensive, fast and high-capacity spinning disks.

Even with explosive data growth, StarWind VTL fits the backup into backup window by accelerating it, so the process does not overlap with production time. Optionally, it creates additional copy of backup data for better safety. It is also available in a software-only form, as part of StarWind VSAN functionality.

StarWind VTL targets those, who need to replace existing tape backup infrastructure or accelerate it if regulatory requirements prohibit replacement. In case the goal is just virtualizing tape backup or creating a stretched backup infrastructure, StarWind Tape Redirector will come in handy.
