MikaelHellström

IT Manager at Regin Dalarna

Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

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.

More Zadara pros

Cons

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

"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."

"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."

"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."

"I would like to see more VM-Aware features in the next release of this solution."

"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."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

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

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."

"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."

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

"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."

"Currently, when we do firmware upgrades, it sometimes causes issues and is not as nondisruptive as desired."

"There are still some storage features that they lack. For example, other vendors implemented the auto-tiering feature a long time ago, while Zadara Storage Cloud is just coming out with this feature today. So, they are a little bit late compared to the market."

"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."

"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."

More Zadara cons

Pricing and Cost Advice

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

"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."

"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."

"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."

"Our customers have seen a reduction in TCO."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

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

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

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

"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."

"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."

"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."

"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."

"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.”
