Solutions Architect at Recovery Point Systems

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.

Auto-scaling capabilities enhance file management while reducing downtime

The most valuable feature of Amazon EFS is its auto-scaling capability. It's really easy to configure EFS by just creating it and running a command to directly configure it with my servers. It supports unlimited use, and charges are applied based on the file usage at the end of the month. The solution offers reduced downtime and increased durability through its auto-scaling features.

Cost-efficient, highly scalable, and installable on different types of hardware

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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"The most valuable feature is Safe Mode."

"The solution provides many controllers."

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

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

"The most valuable feature of this solution is performance."

"It is very easy to use, and it is very fast."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"The product is scalable and easy to expand."

More Pure Storage FlashBlade pros

"Amazon EFS is extremely stable, as it is managed by AWS."

"The solution's technical support is good."

"Elastic File Systems allow me to share data, provision, and manage capacity and performance in AWS."

"The first valuable thing is it is scalable."

"The platform is highly scalable."

"We can run code and deploy it whenever we want."

"We are not that big of a cloud user. We just use it for the storage of our bytes. The most valuable aspect is the storage."

"The initial setup was straightforward."

More Amazon EFS (Elastic File System) pros

"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."

"I would rate QoreStor a ten out of ten for what it offers for the price."

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

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

"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."

"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."

"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."

"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."

More Quest QoreStor 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."

"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."

"The documentational aspect of FlashBlade needs improvement."

"I would like to see better integration."

"I would like to see more deduplication."

"The solution is expensive."

"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."

"There could be improvements in public cloud integration."

More Pure Storage FlashBlade cons

"The platform's connectivity could be improved to be more comparable to S3 buckets, which offer better API availability."

"The main challenge with EFS is its cost, which is slightly higher compared to EBS or S3."

"It should be simplified. There are people who don't have cloud experience. It should be storage that we are able to just connect to."

"There are challenges related to AWS, such as ensuring proper security measures with IMS code and encryption."

"It could be better in connecting with Windows Server instances."

"The lack of transparency in the costs attached to the product is an area of concern where improvements are required."

"The user activity needs to be more connected."

"Elastic File Systems can be expensive due to the nature of data transfer costs, using services like SSTP, and potentially being costly in a rate-shift context."

More Amazon EFS (Elastic File System) cons

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"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."

"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."

"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."

"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."

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"The ransomware protection of QoreStor could use improvement."

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

"Our customers have seen a reduction in TCO."

"Licensing fees are paid yearly."

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

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"The product is very expensive."

"The pricing for FlashBlade is between cheap and moderate."

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

More Pure Storage FlashBlade pricing and cost advice

"The product charges are based on the amount of data stored."

"I would rate the pricing 7 out of 10."

"The product's price depends on the services and the size and capacity at which it is used in a business environment."

"Amazon EFS (Elastic File System) offers a pay-as-you-go model, so whenever you use its services, you need to pay."

"It has flexible pricing. You are charged based on your storage."

"The main challenge with EFS is its cost, which is slightly higher compared to EBS or S3. For one GB or ten GB of data, S3 is much cheaper. EFS could cost around $30 to $50 per month for similar usage."

"The solution's price is mid-ranged."

"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."
