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.

Offers performance control and cloud integration while supporting data management with granular flexibility

The scalability of NetApp Cloud Volumes ONTAP is interesting. We have thought about it, but we haven't used it. I think the scalability is something you scale up rather than respond to peak demand. It wouldn't help with outages either; the scaling is manual, and there are no processes we've used to automate that for unexpected scenarios. We like the scalability; it's enough for what we're planning to use, but we haven't used any advanced features. The standard platform is NetApp Cloud Volumes ONTAP, which is their cloud service. In fact, that's probably the most experience I have with NetApp. I've experienced it on-premise, but kind of secondhand.

Meets our customers' needs but they should move towards high-level scaling

I the product already has scalability features, but in terms of size maybe they could do more to work with parent storage and move to high-level scaling. That area, I feel, is a place where there could be some more options in this solution. It would be a way to improve the scalability in another direction, maybe options to scale out rather than just up. So far we have done very few installations. So maybe in the coming days, weeks and months, we would be able to come up with some additional features that are needed, but right now the product has the competitive features that our clients need.

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 features I have experienced are the centralized management and redundancy under speed of the right disk."

"One feature that's particularly valuable for our finance customers is Pure Storage's safe mode. It protects against ransomware attacks by taking snapshots. Our customers were very impressed with this capability. The data reduction is also impressive compared to other providers."

"We experience fast demos and zero downtime; we do not experience any downtime with Pure Storage, thanks to resilience with Safe Mode, integration with backup software, and everything related to cyber resilience."

"The predictive performance analytics is a very good feature, as our system is performing better than before."

"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."

"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."

"Performance, deduplication, compression, and fast response time for requests from servers and applications."

"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."

More Everpure FlashArray pros

"Even with that size of infrastructure, it's being supported by three people, and it's not like we're working 24/7; it gives us the ability to do a lot, to do more with less."

"So a lot of these licenses are at the rate that is required for capacity. So they're they're able to reduce the license consumption and also the consumption of the underlying cloud storage."

"The storage tiering is definitely the most valuable feature... With respect to tiering, the inactive data is pushed to a lower tier where the storage cost is cheap, but the access cost is high."

"The most valuable features are that it's reliable, simple, and performs well."

"The ability for our users to restore data from the Snapshots is very valuable."

"We are definitely in the process of reducing our footprint on our secondary data center and all those snapshots technically reduce tape backup. That's from the protection perspective, but as far as files, it's much easier to use and manage and it's faster, too."

"The ease of use in terms of how the product works is valuable. We are able to work with it and deploy the storage that we need."

"The most valuable feature is the ease of file storage."

More NetApp Cloud Volumes ONTAP pros

"Comparing other products that are competing with Dell EMC (Enhanced Memory Controller), Dell seems to us to always come out on the high-side."

"We are using it as the primary virtualization storage (both for internal corporate users and external customers) for VMware and Hyper-V virtualization platforms."

"The ScaleIO UI: EMC has been working with storage for a long time; therefore, they know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth, and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects."

"Automatic rebalancing is the feature saving administration time, and also auto rebuilding."

Cons

"I would love for them to have a hyper-converged solution."

"Pure will probably have to move to other layers of the stack, not only storage but, maybe, hyperconverged."

"The price should be lower."

"They could improve the price."

"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."

"Pure Storage support could be a little better."

"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."

"The price is too high."

More Everpure FlashArray cons

"The data tiering needs improvement. E.g., moving hard data to faster disks."

"NetApp Cloud Volumes ONTAP does have a bit of initial complexity for users who are new to the system."

"Multipathing for iSCSI LUNs is difficult to deal with from the client-side and I'd love to see a single entry point that can be moved around within the cluster to simplify the client configuration."

"We've just been dealing with general pre-requisite infrastructure configuration challenges. Once those are out of the way, it is easy."

"NetApp Cloud Volumes ONTAP needs to have customizable pricing options such as 10 TB increments. They seem to have only two options: 10 TB or 250 TB."

"NetApp's support could improve"

"We have had issues with everything failing back 100 percent correctly."

"I'm very happy with the solution, the only thing that needs improvement is the web services API. It could be a little bit more straightforward. That's my only issue with it. It can get pretty complex."

More NetApp Cloud Volumes ONTAP cons

"It would be nice to set minimum IOPS per volume, besides just the maximum, to be able to satisfy this demand from customers out-of-the-box, not by calculating number of disks, etc."

"There is room for improvement in the area of horizontal scaling."

"Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS. We have to provide graphing by Prometheus and Grafana, which would be a good new feature in ScaleIO."

"If they could introduce a write cache feature, the product would be perfect overall."

"I think ScaleIO already has some features for scalability as it is part of the reason for the product, but in terms of size, maybe they should try to address parent storage."

Pricing and Cost Advice

"I would rate it a seven out of ten for pricing. It could be improved."

"The pricing is very attractive and it delivers performance for the money."

"Pricing is very competitive, and it's better than other competitors."

"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."

"The price is reasonable."

"Pure came in at a better price point than EMC and performed better than Compellent."

"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."

"It is cheaper than NetApp."

More Everpure FlashArray pricing and cost advice

"Cloud is cloud. It's still expensive. Any good solution comes with a price tag. That's where we are looking to see how well we can manage our data in the cloud by trying to optimize the costs."

"Some flexibility around the licensing model would help. The product is licensed based on capacity. Basically, the largest capacity license that you can buy is 368 terabytes. At this point, NetApp is addressing some people's concerns around this."

"Purchasing through the AWS Marketplace was good, but it was a test system, not a real purchase."

"It is not a cheap solution because we need to pay for the license and pay for Azure resources as well."

"If a customer is only using, say, less than 10 terabytes, I don't think CVO would be a good option. A customer using at least 100 or 200 terabytes should get a reasonable price from NetApp."

"The solution's pricing is reasonable."

"Our licensing is based on a yearly subscription. That is an additional cost, but because of the storage efficiencies that the NetApp gives, even with the additional cost of the NetApp license, you still end up saving money versus straight Azure native for storage. It's definitely worth it."

"For NetApp it's about $20,000 for a single node and $30,000 for the HA."
