Chief Technology Officer at Lambda256

Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Reliable and secure storage solution supports core banking operations effectively

The replication technology that Hitachi Virtual Storage Platform uses is quite older, and the replication methodology they employ for data between the data center and the production and standby database shows no significant improvement in that particular field. With respect to storage administration, I'd like to see more clarity on the encryption side; data being stored in an encrypted manner is essential, but the customer or end-user doesn't understand which encryption is being used and doesn't have a direct view stating that their data is encrypted using AES 256 or DES, or whatever standard they follow. This lack of transparency may not be acceptable during audits.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

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

Pros

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"The latency is good."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"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."

"I appreciate the performance."

More Pure FlashArray X NVMe pros

"The first thing that attracted this model to us was the non-disruptive migration. We had a very large database application that was on older gear and needed to be migrated to these arrays. We had experience with virtualizing behind an array and moving applications and data but this made it even better."

"The product has great data storage performance with a 100% data security and availability guarantee."

"The setup is very easy to manage and configure. The initial setup and takes one hour more or less."

"The most valuable feature is that you can use it with all deployment models."

"It's a state of the art solution in storage systems. High-availability and performance are the strongest aspects of these machines."

"The most valuable feature is that it has 'eight nines' availability, 99.999999 percent of the time. That is the main selling point."

"The service provided by Hitachi is good, and I get the IT support I need from the vendors."

"The hybrid array provides scaleable, predictable, high performance with no capacity constraints."

More Hitachi Virtual Storage Platform pros

"The most valuable feature is definitely the always-on data deduplication."

"Logic/software management"

"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."

"The GUI is very straightforward and easy to use."

"Implementation of the solution is very simple."

"Latency is definitely the big key for us."

"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."

"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."

More Kaminario K2 [EOL] pros

Cons

"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."

"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."

"There is room for improvement in the pricing of the product."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

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

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

More Pure FlashArray X NVMe cons

"The complex setup phase is an area where improvements are needed."

"The solution is stable. However, there have been some software crashes where we had to restart the system. They could improve the hardware to prevent this type of issue."

"The distributor needs more knowledgeable resources for technical support. It would be better to connect directly to the vendor in case of queries."

"Hitachi Virtual Storage Platform needs to improve its scalability options where there are a few shortcomings."

"The initial deployment was somewhat complex when it came to the installation because of the network connectivity. It was more difficult, in this specific case, than with other platforms."

"The centralized management console in Hitachi Virtual Storage Platform is not very comfortable and user-friendly."

"They should look at the cost because there are other vendors who offer the same cost with more features."

"The solution is priced higher than its competitors."

More Hitachi Virtual Storage Platform cons

"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

"The front panel of the drive shelf doesn't always seat firmly."

"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."

"A single pane of glass to monitor/manage multiple arrays would be helpful."

"I would like them to improve the look of the product’s external casing and shelves."

"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."

"The management graphical interface needs more improvement."

"I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

"Given its price, Pure is not the first option."

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

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

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"The licensing is on a yearly basis."

"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."

"The product is expensive."

More Pure FlashArray X NVMe pricing and cost advice

"Our main issue with the Hitachi G-Series is what we consider to be an archaic software licensing scheme and high maintenance costs."

"In our company, we only pay towards the licensing charges associated with Forcepoint, as Hitachi is considered to be a third-party product for us."

"A drawback of Hitachi storage systems is that they are expensive. The upfront cost is very high compared to others. But when you compare the IOPS at the same price, Hitachi gives you better business value..."

"When you are looking for high-end solutions such as this, price is less important than stability and availability."

"The licensing cost of Hitachi Virtual Storage Platform G Series, whether it would be high or more affordable, would depend on location. For example, here in Brazil, Hitachi charges in dollars and this means my company still needs to convert that into local currency. Sometimes, my company also needs to discuss the pricing with the Hitachi sales team and request for a discount. At the moment, pricing for Hitachi is high, but my team can have some global funding or global accounts that would help reach the price my company is aiming for."

"This is an expensive solution."

"Considering the solution's price, it is very competitive compared to the other competitors in the market. I rate the product price a nine out of ten."

"Hitachi Virtual Storage Platform is a very expensive product."

More Hitachi Virtual Storage Platform pricing and cost advice

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"The licensing is all-inclusive."

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"Kaminario is very competitive on price. They also have a pay per TB model."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."
