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.

Unified storage solution supports cross-vendor replication and diverse industries
One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.

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.

Quotes from Members

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

Pros

"Non-disruptive upgrades: You can upgrade at anytime without worry."
"The performance is great."
"The support has been very good from Pure Storage FlashArray."
"This solution has improved the way our organization functions through its reliability and consistent platform for storage and has helped us to simplify storage because the management tools make everything a lot easier."
"The biggest return on investment for us is not having to do a swap out of the arrays every five years."
"Overall, I am sure that Everpure FlashArray is the best option on the market."
"From the performance that I've seen, the simplicity of how to use it, the responsiveness, and customer experience, it is one of the best companies that I have worked with so far."
"The amount of throughput that we're getting is really nice."
"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."
"It provides transparency, because of its advanced copy features."
"I like that it can virtualize more than three hundred storage providers."
"I think probably one of the biggest benefits of this solution is that it is relatively easy to use and easy to understand."
"It helps us to reduce time, reduce complexity, and be more responsive to requests instead of taking an hour to do one volume; now I can do one volume in less than two minutes."
"I love Spectrum Virtualize."
"Stability has been outstanding."
"It has significantly lowered management cost, overhead, and everything else."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."
"Quest QoreStor is very stable compared to our previous solution."
"Quest QoreStor definitely saved us money."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
 

Cons

"For large storage needs, it is expensive."
"In the next release I would like to see integration into other third-party player providers like Google."
"We haven't seen ROI yet."
"The only minor issues that come to mind are that, every once in a while, a hard drive will go bad. Also, the solution should be cheaper."
"I would like to have support available in Spanish."
"The solution could improve by having a multi-tenant feature."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."
"The product should have better management capabilities."
"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."
"It's been pretty stable, but we've had some issues. I wouldn't say it's poor, but the resiliency has been less than what we expect from an enterprise class product."
"Technical support can be improved in terms of the knowledge base for the first level of support. We have to reach the second level to receive good support."
"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."
"Level 1 technical support needs improvement."
"Anything which improves performance and the ability of our systems would be a nice."
"The setup of the software is definitely not the easiest thing in the world."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"The ransomware protection of QoreStor could use improvement."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
 

Pricing and Cost Advice

"We purchased a license to use this solution and we pay for the storage ourselves."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"FlashArray is expensive, but the quality justifies the price."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"The licensing is $100,000."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"This solution came as an additional cost for the TSM package we chose."
"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"I think it is a good value for the price."
"It has a lot of advanced functions for a reasonable price."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."
"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."
"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."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
