Sowjanya MV

Technical Lead at Wipro Limited

Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades

The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Sachin Prakash

Assistant Consultant at a tech vendor with 10,001+ employees

Has optimized performance using cluster deployment and distributed file access but needs better visibility into network dependencies

IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM. This is one of the features I appreciate most because if you have existing infrastructure at your site but don't want to reinvest in hardware, you can purchase IBM Spectrum Scale software and deploy it as software-defined storage. Users can comfortably access data from their host to the storage host without relying on new network setup when deploying GPFS as it uses the existing corporate network. However, high-speed ethernet network is required. By adding switches to the same network where client hosts reside and deploying GPFS storage array, any file system created on the storage cluster can grant export permissions determining which hosts can access specific file systems. These hosts can directly mount them as remote file systems. The process is simpler compared to defining IQN for providing access to client hosts. Creating a cluster for clients with virtual machines or physical Linux/Windows machines requires installing GPFS services on client nodes, which creates a client cluster. Access is defined on the storage cluster for the particular client cluster, allowing all hosts in that client cluster to mount file systems with granted permissions.

Adeilson Araujo

Arquiteto De Cloud at Claro Brasil

Hybrid data migration has reduced costs and now needs stronger security and database integration

I would like to share something that I believe could improve Zadara's process, which is the issue of communication with databases. Today we have MongoDB as a cloud service, so integration with databases in Zadara would bring better performance in connection in SaaS models and in dynamic models that could bring a platform and a solution that could increase Zadara's usage in the market and in its business scope. Zadara can improve in the database integration area as I mentioned. Zadara can have better dynamism such as MongoDB in SaaS and bring this better dynamism by connecting and offering it within the clouds as a possibility of block storage within that partner cloud, such as AWS EBS, Google's cloud storage, or something within Azure. Creating a stronger partnership where this block storage can become an API connectable across various clouds but native to those clouds would be beneficial. I noticed simplicity in the security part during the time I used Zadara, so I believe Zadara's security needs to improve to provide more and deliver more security visibility to the end customer so that they feel more secure with data encryption and attack protection. A WAF on the API connection that goes through greater protection, something along those lines, could help guarantee that the data is protected by Zadara.

Quotes from Members

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

Pros

"I never have to worry about its performance or if it is the root cause of an issue."

"The most valuable feature of this solution is the support."

"The features that are there now are really what we need."

"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."

"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."

"It saved a lot of space, as far as physical space in our data center."

"Pure Storage has been the go-to storage array for me; it's a lot smaller, easier to set up, faster to upgrade, more reliable, and the performance is very stable."

"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."

More Everpure FlashArray pros

"There is nothing else that even compares to Spectrum Scale."

"The profile share is a valuable feature."

"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."

"It is incredibly scalable and stable."

"We use it for our data over multiple systems, and at the same time it is a shared file system that works pretty well for the most part."

"The high performance of the solution is its most valuable aspect; if you compare it to other storage solutions, it is much better."

"The most valuable feature is the ability to share files across different platforms."

"I rate this product ten out of ten."

More IBM Spectrum Scale pros

"Zadara offered better cost and better cost-benefit regarding cloud compatibility and also data traffic over the internet."

"Zadara has positively impacted my organization as it has added power and momentum to our vision, particularly when working with AI."

"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."

"The most valuable feature of Zadara is its ease of use and safety, and overall the solution is a complete package with all the features needed."

"Zadara is a key underpinning of that because, without that common storage layer and the services running on top of that, we wouldn't have a business to run."

"Compared to us trying to do this ourselves, we've probably seen about 50 to 60 percent in cost savings over the last five years."

"Zadara offers competitive services that are among the best options available for storage services and cloud computing."

"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."

More Zadara pros

Cons

"Some of the issues are that it's probably not on a par with other large storage enterprise type products."

"During heavy load situations with 100K IOPS on one specific port, it requires more granularity level for distribution."

"Technical support needs improvement. With respect to them being able to respond, they're more marketing people, less technical."

"CIFS and SMB Shares cannot be mounted directly."

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."

"They should work on their upgrades, they're not smooth."

"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."

"Reports of performance and LUN utilization could be improved."

More Everpure FlashArray cons

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

"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."

"We do have some issues where Spectrum Scale does not work as expected."

"The biggest problem is that it is not able to provide block storage."

"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."

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

"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."

More IBM Spectrum Scale cons

"Zadara can be improved by making their interfaces more attractive. They currently look like simple PHP interfaces, but they need to customize and work on their interfaces and user interfaces significantly."

"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."

"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."

"We had a lot of issues with the Zadara recently regarding performance, reports, and offloads, the customers could not send backups to Zadara."

"The initial setup of the solution is complex."

"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."

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

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

More Zadara cons

Pricing and Cost Advice

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."

"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."

"The licensing is $100,000."

"Pure has been flexible with us on the pricing models."

"Our costs are around $100,000."

"There are no licensing fees or other costs."

"The price is very reasonable when compared to other solutions."

"For us, as the customer, it reduced the price of the management."

More Everpure FlashArray pricing and cost advice

"The licensing is based on the number of terabytes."

"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."

"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."

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

"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 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."

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

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

"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."
