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

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"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."

"I find Zadara's user-friendliness from both the customer and engineering perspectives highly appreciated."

"One of the most useful features is that they provide iSCSI as a service."

More Zadara pros

Cons

"The documentational aspect of FlashBlade needs improvement."

"The solution is expensive."

"I would like to see more deduplication."

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

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"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."

"There could be improvements in public cloud integration."

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

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."

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

"Documentation management could be improved"

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

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

"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."

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

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

More Microsoft Storage Spaces Direct cons

"I would like to see them be a little bit more proactive in terms of the patches and updates that are available. I would like to see more disclosure and information around what fixes or what enhancements are available within a patch, and help in coordinating and scheduling that. Right now, it's driven more by the customer in reaching out via a support ticket."

"The management interface is more geared towards end-users rather than a service partner like ourselves, and there are improvements that can be made around that."

"Having iSCSI over the internet using a VPN, the IPSec tunnel is really the only thing that I find missing from this product."

"The initial setup of the solution is complex."

"The range of support of VMware could be better. It can support Windows, however, it cannot support other operating systems like IBM AIX. This needs to improve."

"Cost-wise, because it's a pay-per-use model, it may ultimately end up costing us more in the long run than something we developed ourselves."

"There is room for improvement in pricing as it is currently quite expensive."

"The initial installation was difficult because many steps required the command line interface (CLI). Maintenance can also be complicated, especially when deeper troubleshooting requires navigating the CLI and searching for logs."

More Zadara cons

Pricing and Cost Advice

"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."

"Licensing fees are paid yearly."

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

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

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

"Our licensing is renewed annually."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"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."

More Pure Storage FlashBlade pricing and cost advice

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

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

"The solution is expensive."

"The pricing and licensing are very simple and the cost is predictable, although, like everything that you pay for as you use, you have to be mindful of what you're using."

"If you just take the street price of Zadara Storage Cloud and look up the price or cost per hour, then you could think that Zadara Storage Cloud is extremely expensive or a solution only for enterprise use. That is not true. You need to compare the entire system. This means that you don't stop looking at just the street price, but you need to consider all the features, requirements, and costs of support as well as the extra cost that other vendors have. Other players just play with hidden, additional costs. Everything is included in Zadara Storage Cloud's licensing cost; what you get is what you pay for."

"The pricing is very competitive and the fact that they have very compelling discounts for multi-year commitments is great."

"For our use, it's appropriately priced and overall, it's proved to be very cost-effective against other tier-one vendors."

"The price of Zadara is very good and it covers everything. There is no subscription needed."

"One of the factors that ruled out several providers was cost. They were way too expensive for the volume of data that we needed and the speed at which we needed to be able to manage it. There aren't a lot of providers that can do that."

"It is a nice licensing model and it makes it quite simple because we just pay for what we use, and the bill that comes shows us exactly what customers are using what resources."

MS Storage Spaces Direct

No data available

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

Zadara is a powerful enterprise-level storage solution whose design enables it to handle every aspect of a user’s data storage needs. It can be deployed in any location, using any protocol, and storing any data type that an organization requires. With Zadara, organizations can do everything that they were able to do with more traditional systems in a cheaper and more efficient way.

Zadara Benefits

Some of the ways that organizations can benefit by choosing to deploy Zadara include:

Security. Zadara is built with data security in mind. All of a user’s data is heavily encrypted by Zadara’s software so that it is safe both while it is in storage and while it is being transferred somewhere else. It comes with role-based access controls that prevent a user’s data from being seen by those who lack the proper level of authorization. It also comes with dual-factor authentication and other similar methods of identity management.

Reduced costs. While Zadara offers enterprise-level storage capabilities, the costs associated with utilizing it are far less than those of similar solutions. Some of the resources that it offers are totally free of cost. The model that it utilizes is a pay-as-you-go model. Organizations only pay for the resources that they use and nothing more. Users are not required to sign up for any particular period of time. They are in complete and total control of what they spend on the solution.

Storage efficiency. Zadara ensures that users are able to store their data in the most efficient way possible. It takes a number of approaches that prevent insufficient data storage. These approaches are:

1. Thin-provision volumes. This method only allows actually written data to be counted toward the storage capacity that is consumed.

2. Pattern removal. Zadara searches a user’s stored data for repetitive binary sequences. Once it identifies the repetitive binary sequences, it deletes them.

3. Inline deduplication (all-flash only). This method ensures that Zadara only stores unique data blocks in its system.

4. Inline compression. Zadara takes data that is stored in its system and compresses it. This keeps larger blocks of data from taking up too much room.

Zadara Features

Centralized management. Zadara comes with a centralized dashboard that enables organizations to monitor and control their storage operations from a single location.

File analytics. Organizations can leverage a powerful analytics package that can provide them with critical insights. These tools can help users sort through their data and make more informed data management decisions.

Remote mirroring. This feature enables users to replicate data in two remote locations at the same time. This makes it easy for data to be recovered in the event of an unexpected loss. It also aids remote teams in their collaboration efforts by giving them access to the same data at the same time.

Reviews from Real Users

Zadara is a highly effective solution that stands out when compared to many of its competitors. Two major advantages it offers are its extensive suite of cloud solution integrations and its object storage capability.

Steve H., the chief technology officer at Pratum, writes, “One of the most valuable features is its integration with other cloud solutions. We have a presence within Amazon EC2 and we leverage computer instances there. Being able to integrate with computing, both locally within Zadara, as well as with other cloud vendors such as Amazon, is very helpful, while also being able to maintain extremely low latency between those connections.”

Mauro R., the CEO of Momit SRL, says, “The object storage feature is wonderful. With traditional storage, you have a cost per gigabyte that is extremely high or related to the number of disks. With Zadara Storage Cloud, you have a cost per gigabyte that you can cut and tailor to your needs independent of the number or size of the disks.”
