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

"It simplifies the overall management. We don't have to worry about storage anymore."

"Firstly, dedupe is the most valuable feature, hands down, and simplifying storage is also a big win overall."

"We were previously on legacy storage systems, and after moving to Pure Storage, our stability and performance both drastically improved."

"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."

"Performance is the most valuable feature."

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

"All my customers are pretty happy with most Pure Storage solutions."

"The top-tier support and reliable storage are the most valuable features of this solution."

More Everpure FlashArray pros

"The solution provides us unified storage, no matter what kind of data we have."

"The most valuable features are tiering to S3 and being able to turn it on and off, based on a schedule."

"The initial setup was straightforward. We started with a small pilot and we then moved to production with no downtime at all."

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

"One of the features our customers like is that it can be used from one cloud provider to another. They can use it from Azure to AWS or vice versa. That way, they don't need to use the same provider for backups. If something goes wrong on the primary site, having the same data in another cloud service provider is important."

"The solution's high-availability features are cost-effective for us because we are able to use the cloud benefits to reduce the cost of DR."

"Los resultados son sorprendentes en términos de funcionalidad y defensa contra terceros."

"It functions and I think in the future it will be a reasonable method of getting NFS in the cloud."

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."

"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."

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

Cons

"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."

"Self-backup is the only feature lacking in this solution."

"Currently, the solution fails to support file screening."

"It needs to improve its price."

"If they could make it cheaper, that would be something."

"I would like a feature to integrate with external or cloud solutions."

"The price could be better."

"In the next release of the solution I would like to see Vormetric native block encryption."

More Everpure FlashArray cons

"I would like some more performance matrices to know what it is doing."

"The navigation on some of the configuration parameters is a bit cumbersome, making the learning curve on functions somewhat steep."

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

"The solution is not stable when using single nodes. This is a problem. NetApp should work on this solution to make it more stable with HA nodes and resolve this issue."

"We would like to have support for high availability in multi-regions."

"Something we would like to see is the ability to better manage the setup and tie it to our configuration management database. We manage our whole IT infrastructure out of that database."

"I would want more visibility and data analytics where we can see anomalies within the shares within the GUI."

"Their support and development teams can collaborate better to resolve an issue."

More NetApp Cloud Volumes ONTAP cons

"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."

"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."

"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."

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

Pricing and Cost Advice

"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."

"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."

"We have seen a reduction in total cost of ownership (TCO)."

"We do not incur additional costs beyond the licensing fee."

"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."

"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."

"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."

"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."

More Everpure FlashArray pricing and cost advice

"The pricing could be improved. It is a good product, but it is very expensive for me."

"For enterprise customers, it's a very cost effective. But in the SMB segment, yeah, pricing is a little bit challenge for your time."

"Our licensing costs are folded into the hardware purchases and I have never differentiated between the two."

"It is expensive. There are no costs in addition to their standard licensing fees."

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

"I know the licensing is a bit on the high-end. That's when we had to downsize our MetroCluster disks and just migrate to disks that were half used. We migrated into those just to reduce maintenance costs."

"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."

"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."
