Sowjanya MV

Technical Lead at Wipro Limited

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.

Sr. Project Manager IT at ITC Ltd

High‑performance all‑flash storage has transformed data warehousing and reporting speed

The features of Dell PowerMax that I find most valuable so far include its all-flash capability, along with its performance, reliability, and efficiency. Additionally, it has snapshot-level features that allow me to take snapshots or backups within only a few seconds. There is no need to wait long, and unnecessary high bandwidth used for backup does not occur because I can take the whole snapshot backup within a fraction of a second. I have used the deduplication feature of Dell PowerMax. Deduplication and compression are very effective, so despite my large amount of data, the effective size is reduced due to this deduplication and compression, allowing me to store more data on the same storage. Regarding the impact of Dell PowerMax's real-time data encryption on my data protection strategies, I have not used that feature personally. However, in another department, my colleagues are using it, and they have not faced any performance bottlenecks due to data encryption. The encryption is very powerful, but I have not implemented that encryption in our database data warehouse systems since they are for internal use only, not exposed worldwide. At first, I faced several issues, and our report rendering complaints were quite annoying. However, now with Dell PowerMax storage's high IOPS handling capabilities, the output comes within a fraction of a second, making our users happy. Whatever our requirement or demand is, it has already been implemented in Dell PowerMax with its all-flash NVMe storage. New bricks can also be added if a size increase is required, allowing for additional bricks to be added as needed. Everything is in place; therefore, I do not think any other improvements are required. However, it is worth noting that Dell is continuously inventing and releasing more powerful types of storage. This results in increased reliability, enhanced data handling capabilities, improved deduplication ratios, and the fulfillment of more IOPS demand.

Has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category

VIOLIN QV2020 lacks scalability. This affects both the timeframe for installation and the performance of end-users. Additionally, there's a challenge in deploying horizontally, either by deploying between different nodes or adding new ones. We have many customers. 50,000 users are using this solution. It depends on the projects being taken out of the operations team.

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 it never goes down. We can expand and create volumes."

"The deduplication and compression rates are beyond impressive."

"Performance, dedupe, and that it works well with database workloads are its most valuable features."

"The biggest lesson that I have learned from using Pure FlashArray is that it's user-friendly, easy to manage, and very flexible."

"If I want a product which has reliability and high speed, and Pure Storage is the first name that comes out of my mouth."

"The speed is the most valuable feature of this solution."

"The solution offers amazing performance."

"Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."

More Everpure FlashArray pros

"The smaller footprint of the device has been really nice. We have gone from eight bays to one bay. Having one floor tile in our data center has been pretty awesome. A lot less power and HVAC cooling is being consumed."

"The solution is stable. I would rate it ten out of ten."

"The product is very fast and reliable."

"Symmetrix has always been a high-end, high availability system where we have never had one go down."

"I am impressed with the tool's reliability since we see a few hardware failures with it. Also, the solution's replication configuration is good."

"The stability is great. It is five nines."

"It is a fantastic Dell EMC product ever competing with all the vendors. It stands out in terms of performance. You can ask for mission-critical application workloads."

"It's faster and more resilient."

More Dell PowerMax pros

"It has lowered batch times from 14 hours to two hours."

"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."

"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."

Cons

"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."

"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."

"The only issue is the pricing. Because we have competition, our customers always take another brand and say they can save their investment."

"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."

"We would like to be able to connect to data tape for backup, specifically to the LTO backups."

"The capability from Pure as far as sharing out files and things of that nature is a little bit lacking."

"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."

"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."

More Everpure FlashArray cons

"The technical support is lacking. We are working with Dell EMC to get some better understanding of this."

"I would like to see the rack change. They have defaulted to the standard rack, so our fiber cables are crowded when we shut our back door."

"The management interface needs improvement. It shouldn't be as hard to do some of the functions as it is."

"I would appreciate seeing Dell PowerMax improve by having more flexible configuration options, specifically from physical configurations that are less constrained to Dell racking."

"Support of the product can be slow and an administrative challenge: planning, scheduling, and overseeing data center access for a Dell EMC rep."

"We have had some trouble with the VMAX-to-PowerMax migration, but the VMAX box will be powered down after the migration. The PowerMax boxes are working fine and we don't have any issues with them."

"We've had issues with whole waves of memory DIMMs that had to be replaced in a machine, which is 32 sticks of memory in one director. It was a tedious day; we've had that on multiple arrays due to a bad batch of memory."

"PowerMax's software is highly stable, but we faced two hardware issues in one year. We had a failure of the storage director module, and the physical disk failed on another occasion. Dell EMC should improve its hardware quality."

More Dell PowerMax cons

"VIMM replacement is poorly designed."

"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."

"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."

Pricing and Cost Advice

"The price is very reasonable when compared to other solutions."

"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."

"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."

"The solution could be cheaper."

"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."

"We have seen a reduction in TCO."

"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."

"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."

More Everpure FlashArray pricing and cost advice

"From a general capital investment, it's one of the higher price points in the market. It depends on the size and software features that you would include in a system. So, the cost varies dramatically."

"The PowerMax appliance pricing was reasonable. Dell EMC quoted us a substantial discount."

"The cost is expensive. While VMAX now has good pricing, PowerMax is a little expensive."

"I think it is an expensive tool, but it is the best product. I think it is expensive and the cost one must pay for the best solution."

"The price is really high."

"The labor savings and support have been significant. If we're talking 100 hours of labor every three months, that is 100 hours of a database engineer costs. There are performance latency numbers as well as costs associated with recovering data that gets lost, and this system doesn't lose data. You can look at numbers that go around the cost of downtime, if data is not available. This system doesn't go down. Everyone's ROI is going to be unique, but the dependability and performance of the system combined with its ease of operation will definitely save businesses of all sizes money."

"One area for improvement, one that everybody always comes to, is price... it's still quite expensive to purchase these big arrays... For us, the pricing doesn't make Dell EMC uncompetitive."

"It scales enormously, but it's expensive to do so."

"They will beat anyone’s price right now. They are struggling and just need to get product out their doors."
