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.

Ease of implementation and robust performance enhance multi-OEM support experience

We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

The Nimble CS-Series has proven to be reliable with 100% uptime

When we started the process of looking for a SAN vendor I had four primary criteria: reliability, performance, cost, and simplicity. We were really looking for a unicorn and were fully expected to have to make compromises in one of those areas. The Nimble CS-Series was recommended by our solutions provider, and we were blown away. Not only was it the most affordable option, but it was the easiest to deploy, had the best performance, and has proven to be reliable with 100% uptime.

Quotes from Members

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

Pros

"Data deduplication features make it easier to manage storage and forecast growth."

"The management features are well organized and they have a very good dashboard."

"One could tell, the minute we switched to this program, everything ran a lot faster."

"I have seen a huge increase in speed and performance on our databases."

"After the implementation, the time to run the process was reduced to minutes and it did not require any manual intervention from our DBAs."

"It saved a lot of space, as far as physical space in our data center."

"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."

"Pure Storage FlashArray's overall speed is its most valuable feature."

More Everpure FlashArray pros

"There are some alternatives, but what we've found, working with our partners, for mid-range storage it's probably the best one you could choose."

"It is very stable."

"It is scalable. We can add additional tools if we need to expand it."

"Overall this solution provides exactly what we needed, which is fiber channel block storage in the cloud."

"From my experience, EMC provides good support, and Dell's service is very good."

"The most valuable features are its performance and simplicity."

"Quick Snapshots and cloning are key features."

"The initial setup is very easy. I would rate my experience with the initial setup a nine out of ten, with one being difficult and ten being easy."

More Dell Unity XT pros

"Reliability, excellent support by EMC, and VMware integration High availability including non-disruptive updates: We cannot afford downtime windows."

"I have worked on CLARiiON and all series of VNX."

"If you are looking for a stable, powerful and effective entry level SAN that you can provision on your own for a small environment or a small office/remote office situation - this is definitely the product for you."

"Depending on how simple the customer needs it to be, might sway my recommendation one way or the other, but in terms of functionality, VNX is very very good."

"Tiering, because it allows your data to dynamically move among different disk types based on demand in the last 24 hours."

"Since implementing VNX, we achieved a 10 times increase in the performance for its end users."

"The most valuable feature is the auto-tiering, which helps in the speed of data access."

"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."

More VNX [EOL] pros

Cons

"On the technical side, the way that the array performs cleanup and garbage collection sometimes pushes it close to 100 percent utilization, causing some stress."

"For large storage needs, it is expensive."

"The price could be better."

"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."

"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."

"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."

"The solution is not cheap. It's much more expensive than DataCore."

"We have not seen a reduction in our TCO nor have we seen ROI."

More Everpure FlashArray cons

"The reports could possibly export all the data at once."

"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to be enhanced."

"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."

"Dell operates at the commodity end of the market, so if they really want to get into storage in a big way, they need to have better pre-sales technical support and engagement."

"They should update to the cloud."

"Inline dedup compression security is coming up as an issue, encryption, etc. is key for our customers. If we could have more ways to do software-based encryption, those are the features customers are asking us for, as well as replication."

"The only challenge I've ever had was with a Drive firmware upgrade."

"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."

More Dell Unity XT cons

"It only supports 10Gb copper, and cannot do 10Gb fiber."

"With this product, the licensing software and capacity are very expensive."

"EMC products are costly when compared to other vendors such HP, Hitachi, Dell, and NetApp."

"Customer Service: I don't like the way EMC's Powerlink support is behind a wall."

"You need a lot of licenses in order to use this product, which makes the product expensive; the maintenance contract price also increases significantly every year."

"We encountered scalability as it is limited by backend slots, and NAS performance is significantly reduced when scaling."

"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."

More VNX [EOL] cons

Pricing and Cost Advice

"The cost was initially high, but once more people were using it, the costs came down. This was because the University was reselling it to other departments."

"It is a more expensive solution, but it is worth it. You are getting what you paid for."

"You get what you pay for. It is expensive, but it really works."

"There are no licensing fees aside from the support."

"We purchased a license to use this solution and we pay for the storage ourselves."

"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."

"We are finding the TCO of flash to be lower than SSD implementations."

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."

More Everpure FlashArray pricing and cost advice

"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."

"This product is cheaper than the EMC VNX solution. It is good for small businesses."

"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."

"The solution is very expensive."

"Licensing is fine. We worked with a sales rep to purchase our Unity."

"I liked the price point when we purchased it."

"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."

"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."

More Dell Unity XT pricing and cost advice

"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."

"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

"Make sure you understand how the licensing works and that you are getting the right set of licenses if you need array-to-array replication."

"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"

"Reducing dependency on JavaServer Pages (JSP) could improve the administrative overhead."

"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."

"While EMC tends to be on the expensive side, the stability and support of their products are top-notch and I feel are worth the cost."

The VNX range is older and is being phased out. I think you mean VNX 5200? That said the Unity 400 is the better investment as it is newer, cheaper to support, faster, and with higher capacity and bigger supported file system size.
