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.

Collaborate effectively with partners and benefit from robust data management capabilities
The functions of HPE StoreOnce that I find most valuable are its deduplication and replication options. These features save data and reduce the size of data significantly. If the actual size for backup data is 100 terabytes, using StoreOnce, it will be around less than 10% of the original size due to the 1 to 10 deduplication ratio. So, compression and replication are critical features I appreciate. Additionally, adaptive backup and restore capabilities of HPE StoreOnce are indeed very helpful functions. As I know from my technical team, the process is very easy for end users because the GUI and user experience with StoreOnce are straightforward. They can restore their backups at any time. An important feature of StoreOnce is that they can reserve an amount of storage capacity as protected capacity for a limited time, safeguarding their data against intrusion and other interactions. Based on feedback from customers, StoreOnce is regarded as a highly useful solution for backup. I am satisfied with the security aspects of HPE StoreOnce, but it's crucial for any company to maintain a multi-layer security approach. Starting with a firewall is essential for maintaining their environment. Additionally, security features on StoreOnce are useful. I believe that no company should rely solely on one layer of security; they should adopt a multi-layer security strategy that begins at the network level and extends to their internal solutions.

Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"Support has been helpful."
"Data reduction and compression. Sub millisecond latency."
"It solved many problems and provided unexpected features that improved our business execution, making us more agile internally."
"From the first test that we have conducted, we are very satisfied with this solution."
"Pure is simple to set up and manage on a day-to-day basis."
"Reliability and performance are its most valuable feature."
"The snapshot feature is valuable. It protects data based on the policy."
"When using de-duplication, backups take less space than they previously did, and this minimizes the costs to our company."
"Most important criteria to look for includes: Price, features, functionality, and ease of use; definitely look at this solution as a viable option as it is cost effective and reliable."
"It is at the top of its class, in my experience."
"Recovery is important."
"Support is the main thing; if we have any issue, it’s easy for us to track or investigate it, because we don’t have different solutions from different vendors."
"The time to do the backups is great for us because the last backups we used to have took at least 8 - 10 hours and at the moment the backups takes one hour or less."
"If you want a reliable and reasonably-priced product, I would recommend it."
"It is an absolutely stable solution; we haven't had any issues, there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
 

Cons

"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"It needs to improve its price."
"It is a bit expensive."
"Pure Storage's logs could provide more visibility to the end-user. The logging algorithms are different from those of other vendors. For example, Cisco's logs provide extensive troubleshooting data, whereas Pure Storage logs offer limited information. We have to contact support to get more information."
"The scalability of the solution is extremely costly."
"If I need to change or troubleshoot the dashboard, I cannot do it without calling support. If I want to move something critical, I cannot do it by myself. The dashboard blocks me from changing those critical things."
"Price is about the only thing that's wrong with it."
"I think that technical support is a weak point. I feel that technical support does not know the product."
"Six months after purchasing StoreOnce, the database became corrupt and the unit had to be replaced."
"So when we had the systems put in the technician that came out actually hadn’t seem them before."
"The solution's pricing could be improved."
"But the initial network setup is not intuitive, and this could be improved."
"It's not big, but it could be smaller and take up less space in the data center."
"We’ve experienced data lost. We’ve had three stores go off-line (which were recoverable) and had a disk become corrupt at the service set/couplet level."
"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"We are finding the TCO of flash to be lower than SSD implementations."
"You get what you pay for. It is expensive, but it really works."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"Pure Storage has not helped to reduce our HANA licensing costs."
"The pricing of Pure Storage FlashArray is reasonable."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"It is light years beyond anything else with the same price point."
"It is cheaper than NetApp."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"We have got a perpetual license, and we have access to all the features. If you are using cloud banks, you can store the internal data in HPE Cloud if needed. You can offload the data to the HPE Cloud. It is a licensed product. We have got around 10 TB of cloud bank storage with a one-time payment. We specifically took 10 TB for very critical offsite backups. We can also increase it in blocks if needed."
"The solution is pretty expensive."
"The price of the product is reasonable."
"HPE StoreOnce is cheaper compared to other solutions in the market."
"I rate the platform's pricing a seven out of ten."
"There are costs for additional storage and space."
"The price puts me off. It's definitely on the high side."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
