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.

HPC CTO at a manufacturing company with 10,001+ employees

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

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

"The initial setup is pretty easy and simple."

"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 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."

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

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

"FlashBlade offers low latency, high throughput, and seamless scalability."

"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

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

"One of the most valuable features is its integration with other cloud solutions. We have a presence within Amazon EC2 and we leverage compute instances in there. Being able to integrate with compute, 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."

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

"A nice feature is the immutable object storage, which can be used in conjunction with Veeam."

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

"Zadara is a fully-fledged platform, and our customers are happy with its use."

"The most valuable features of Zadara are its visibility and simplicity to use."

"Being able to scale on demand, and being able to get out of our security operation center, and not having to purchase hardware upfront, has drastically reduced the overhead that was required to maintain our information. We have also gained additional capabilities in terms of speed of replicating that information."

"Zadara Storage Cloud having 24/7 management saves me support and engineering costs because the storage and computing are managed by a third-party. We are able to focus more attention on the customer, which is truly our core business. Even at 1:00 AM or 2:00 AM at night, someone will answer, which is important."

More Zadara pros

Cons

"I have not seen ROI."

"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."

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

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

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

"I would also like to see better support for CIFS workloads."

"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."

"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."

More Pure Storage FlashBlade cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

"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."

"Some of the features are a little bit slow to come to market."

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

"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."

"The cost is not favorable as Zadara does not provide competitive rates for regions like South Africa and Ethiopia."

"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."

"In the next release, there can be some improvements to the web console by adding more features because the console is simple. Additionally, the calculator could improve."

"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."

More Zadara cons

Pricing and Cost Advice

"We used a reseller for the purchase."

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

"Licensing fees are paid yearly."

"Our licensing is renewed annually."

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

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

"The product is very expensive."

"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

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."

"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."

"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."

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

Innovation to break decades of data storage trade-offs.

VAST Data

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.”
