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.

Extends data management capabilities while offering robust options for further enhancement
Dell ECS provides features such as active-active and geo-replication, which offers a good approach for disaster recovery. As a Dell platinum partner, we appreciate that most Dell portfolio products are integrated together. For example, Dell ECS can be integrated with other file share systems or PowerScale without requiring third-party tools. The integration between Dell products is particularly noteworthy because Dell provides the full cycle of storage solutions, from NAS, SAN, hybrid, to object storage. All these solutions are fully integrated together. The pricing is competitive when compared to other vendors. While comparing with HP's offerings, Dell ECS as object storage is one of the best. Pure Storage might offer better pricing, but you won't find the same level of integration across products if you source the full cycle from one vendor. The complete integration of Dell solutions is one of the main features I appreciate, and I often advise my customers to consider this ecosystem. This integration helps with having a single point of contact and support.

Enables seamless file distribution while benefiting from scalability but could use simplified implementation
IBM Storage Fusion is used in telecoms. It is a file center that receives and shares files. It is also used for writing the CDR zone on the storage, since it offers a cost-effective solution for large-scale storage needs in a telecom setup The deployment of Storage Fusion has been new for us in…

Quotes from Members

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

Pros

"Redundancy and the fault tolerance of the platform are the most impressive."
"The best features of Pure Storage FlashArray are its ease of use and user-friendly interface, and the performance allows all types of services to be visualized from a single point of interface, making it more robust and user-friendly."
"Pure Storage has the right business model and will be around for a long time."
"It's actually very stable"
"It's simple, powerful, and ready to use."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"It has a small footprint, as the current system is only four units per rack, it's got good speed for the price as it uses eMLC, an advanced type of SSD, and it's very scalable, and we're not paying for capacity as we get free controllers every three years."
"The security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."
"Dell EMC provides good service, and their products are easy to use, to install and configure."
"If someone doesn't want to go on the cloud, then this is the best solution that we have in the market right now."
"The setup was straightforward."
"I have found Dell ECS to be scalable."
"The stability is extremely good; it's one of its selling points, we don't have bugs or glitches, it doesn't freeze, and it's completely reliable."
"The most valuable features of Dell ECS are its capability to integrate multiple protocols seamlessly with other Dell solutions like PowerScale and data domain."
"What I like best about Dell ECS is its stability. I also like that you can use it for large-scale data purposes. The solution works fine for me, and I haven't encountered any issues with it."
"I would rate scalability ten out of ten since you buy what you want."
"Fusion provides the ability to install the secret server and distribute files; it serves as a black box where tickets are opened only if issues arise, reducing frequent upgrade problems."
 

Cons

"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"One requested enhancement yet to manifest is the scheduling of snapshot replications."
"We had one instance with an eight-hour outage in our primary data center because the upgrade to the controller failed, and the controller redundancy didn't work."
"The technical support is okay, but could be improved."
"Price per terabyte is substantially higher than their competition. We would like to see it drop."
"We would like to integrate it more with our backup solutions."
"The solution could improve by having a multi-tenant feature."
"The solution is not cheap. It's much more expensive than DataCore."
"We have had issues when the ECS is expiring or the NetBackup is expiring images."
"You should be able to calculate so that when it's full it's 100% full, not just 90%."
"There is room for improvement in the DPI reports, as they could be made more user-friendly."
"It is a good solution, except for the cost."
"In Taiwan, they don't have professional technical support."
"They need to ensure that the system will work if a site goes down."
"The major weakness in the solution is that there is no cloud version for Dell ECS."
"They could provide centralized reports."
"The implementation is complex, especially when using custom servers."
 

Pricing and Cost Advice

"The cost has room for improvement."
"The pricing is reasonable."
"The best features come included without any additional cost."
"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"We do not incur additional costs beyond the licensing fee."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"It is an expensive solution. There is a need to make yearly payments towards the licensing costs attached to the product."
"Dell EMC ECS is too expensive."
"If I remember correctly, Dell ECS is an appliance, so if you buy Dell ECS, you also have to buy the hardware, while IBM is standalone software, so you can buy IBM as software only without needing to buy the hardware. On a scale of one to five, I'm rating the pricing for Dell ECS a four."
"The charges for this solution are made in blocks of models, which are purchased depending on what features an organization requires."
"The product is quite expensive."
"We initially purchased all of the licenses at the same time."
"The solution's cost is quite reasonable."
"It's a lease-based model, so it's capacity-based. We already negotiated the price a lot, but we're still doing that with Dell because somehow the product was not installed successfully, so there was a lot of struggle in the distributor territory between Dell and the environment itself. I would give the solution a 6 out of 10 for the pricing. There's a little room for improvement."
