Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Offers cost-effective storage for small companies with budget constraints

IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies. However, other features like deduplication and compression do not perform effectively. The price sensitivity makes it a viable option for clients with budgetary constraints, as it allows us to secure deals based on the cost rather than advanced performance.

Quotes from Members

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

Pros

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"The initial setup was extremely simple and straightforward."

"The latency is good."

"Technical support has been helpful and responsive."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"It has benefited my organization because it has reduced time to insights."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

More Pure FlashArray X NVMe pros

"The initial setup is straightforward."

"We use IntelliFlash products for larger environments, like Qatar Airways."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"It performed great originally, and when it performed great, it was awesome."

"Data Compression: Up to 80% space reduction in the database"

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

More DDN IntelliFlash pros

"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."

"We've found the solution to be very stable so far."

"The initial setup is straightforward and can be done in an hour and a half by one person."

"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."

"Stability-wise, this solution is fine."

"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."

"The initial customer technical support was efficient and effective."

"IBM FlashSystem is the best solution for storage virtualization."

More IBM FlashSystem pros

Cons

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"The UI for this solution needs to be improved."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"There are some challenges with data encryption and reduction."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

More Pure FlashArray X NVMe cons

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

"Snapshots are not as easy to access as on a NetApp device."

"It's somewhat scalable, but maybe not so much as some of the competition."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"In future releases, I look forward to more AI features."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

More DDN IntelliFlash cons

"Customization features must be improved."

"The solution should improve its pricing and the mechanism in the reduction pool."

"Sometimes the performance is effective but it gets resolved in the process."

"Events/log analysis tools."

"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."

"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."

"I would like to see bigger modules."

"The array level RAID does not seem available."

Pricing and Cost Advice

"Our licensing fees are $500,000+ USD."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"We pay approximately $50,000 USD per year in licensing fees."

"The support cost per array is about $20,000 a year for 24/7 support."

"The product is expensive."

"With VMware, we pay $300,000 annually."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

More Pure FlashArray X NVMe pricing and cost advice

"I think we pay around 100 grand per year for three arrays or four arrays."

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"The cost of the IBM FlashSystem is lower than the HPE solution."

"I price of IBM FlashSystem is reasonable and competitive."

"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."

"Overall the price of the solution is expensive and this includes the license."

"The solution requires a license and could be less expensive."

"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."

"Its price is very good."

"The price is a little bit high so is rated a six out of ten."

Overview

Pure Storage FlashArray//X is the world’s first enterprise-class, all-NVMe flash storage array. It represents a new class of storage – shared accelerated storage, which is a term coined by Gartner – that delivers major breakthroughs in performance, simplicity, and consolidation.

Pure Storage

Western Digital through its IntelliFlash arrays delivers high-performance storage with a complete range of features and connectivity options, including inline compression and deduplication, application and VM consistent snapshots, replication, RAID, data encryption, VMware vCenter integration, and multi-protocol support for SAN (FC, iSCSI) and NAS (NFS, SMBv3). IntelliFlash arrays deliver high availability through dualredundant and hot-swappable components, active/active or active/passive controllers, non-disruptive software upgrades, eMLC flash, and proactive cloud-based monitoring, analytics, and intelligence. A RESTful API provides scripted or programmatic control.

DataDirect Networks

IBM FlashSystem products are enterprise computer data storage systems that store data on flash memory chips. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 acquisition of Texas Memory Systems. This hardware provides performance, reliability, and efficiency benefits versus competitive offerings.
