Juliana Camargo

Vendor business manager at TD SYNNEX BRASIL

AI projects have gained momentum as our team has built a strong pipeline for data‑intensive workloads

The best features Everpure FlashBlade offers, which stand out to both me and our customers, are its exceptional performance for AI and analytics workloads, its ability to scale seamlessly, its unified file and object storage architecture, and simplicity of management. Customers also value the fast backup and recovery capabilities, which are critical for cyber resiliency strategies. One of the challenges we face in Brazil is the price point. Everpure FlashBlade is a premium solution, and for many customers, the initial investment can be difficult to justify unless they have very demanding workloads such as AI, large-scale analytics, high performance, or cyber recovery. Because of this, our focus is on identifying customers where the business value and performance benefits clearly outweigh the cost. Since we have not yet deployed Everpure FlashBlade in production with a customer in Brazil with TDCX, I cannot speak from direct operational experience regarding its positive impact. However, Everpure FlashBlade has helped us engage in strategic conversations around AI, cyber resiliency, and modern data architectures. We have Everpure FlashBlade available in Brazil with TDCX for proof of concept activities, which allows customers to validate performance, scalability, and their real-world use cases before making an investment decision. This has been a significant asset in the presales and technology evangelization process and has helped customers understand the business value of Everpure FlashBlade. We have a proof of concept with a customer called M. Dias Branco in Lardas in Brazil. The project is in progress and we hope to close this sale this year.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options

The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

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

"The main feature I have found to be product replication."

"We can capacity plan at a greater level than we used to."

"This solution has improved how our organization functions in the way that it has essentially made us not have to think about storage."

"The most valuable features are the Metro clustering, and disaster recovery."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"It works quite well for us, and I would recommend it."

"The initial setup is pretty easy and simple."

"Speed and ease of use are the two most valuable features."

More Everpure FlashBlade pros

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."

"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."

"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."

"Quest QoreStor is very stable compared to our previous solution."

More QoreStor pros

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

"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."

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

"Overall Zadara is a useful solution that provides good services."

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

"Zadara was a key enabler for us to be able to enter the cloud business because if it wasn't for them, it would have taken us a lot longer."

"With Zadara Storage Cloud, you simplify the management, which is absolutely true."

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

More Zadara pros

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."

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

"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."

"We have one system at a customer's site that has had a lot of problems over the last year — I think maintenance was required over seven times before everything was corrected."

"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."

"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 not rate Everpure FlashBlade as a perfect score primarily due to the price point in the Brazilian market."

More Everpure FlashBlade cons

"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"The setup of the software is definitely not the easiest thing in the world."

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."

"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."

"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

More QoreStor cons

"Right now, to use Zadara, you have to go through some hoops."

"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."

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

"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."

"I wouldn't say that it's very stable. It can recover from outages, however, there's still room for improvement on the stability."

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

"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 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

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

"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 could be cheaper."

"Our customers have seen a reduction in TCO."

"Licensing fees are paid yearly."

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

"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."

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

More Everpure FlashBlade pricing and cost advice

"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."

"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."

"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."

"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."

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