Sowjanya MV - PeerSpot reviewer
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.

Sales Engineer For Channel Organisation at a tech vendor with 1,001-5,000 employees
Enables seamless data replication and supports comprehensive data analytics workflows
The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites. Also, important is the capability to provide RESTful APIs for custom connectors. In terms of security, I advise customers to rotate access keys to enhance protection. Additionally, scalability is effortless as you can add nodes or expand the license.
Jccerong Heron - PeerSpot reviewer
System Engineer at a tech vendor with 10,001+ employees
Support team has guided us through deploying virtual storage on legacy hardware and reducing operational costs
The reason I chose StarWind Virtual SAN for this particular scenario is really the features, the ease of use, and most importantly, the price. In my opinion, the best features StarWind Virtual SAN offers are easy integration with the system installed in the data center. The integration with my existing systems in the data center works well, especially with VMware, as we already have a big cluster in VMware, and the easy integration with that is helpful to solve some problems with the platform. StarWind Virtual SAN has positively impacted my organization by reducing OPEX costs. My OPEX costs have gone down as we reutilize some old servers, and this reduces the CAPEX of hardware in the data center.

Quotes from Members

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

Pros

"Everpure FlashArray is very user-friendly, easy to learn, and makes it easy to identify issues while providing more redundancy on both the controller and host sides."
"It simplifies building out the storage."
"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"Their evergreen solution is probably the most needed in any industry, especially today in unprecedented times and supply chain issues, their evergreen solution is amazing."
"They have a very good support system, and the GUI is also very intuitive."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"The most valuable feature of this solution is the support."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"IBM has the most number of additional services, this is the main advantage."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
"One of Cloud Object Storage's best features is infinite capacity."
"One of Cloud Object Storage's best features is infinite capacity. This is one of the main advantages if you don't want to use your own storage. You also have the ability to write only, write once, and read many. It's like tape storage but software-based. This feature is essential for financial institutions that require that kind of protection if you write backup or data there."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"It eliminates the use of expensive physical shared storage."
"The feature I have found most valuable in VSAN is its high availability capability."
"This combination of low price with enterprise-grade HA features is key in the market."
"The user interface for this application is amazing."
"StarWind vSAN has a lot of great features and is a perfect solution for mirroring internal disks and flash between servers."
"Existing common-purpose servers were transformed into flexible, redundant, high-performance storage clusters."
"Before VSAN, hypervisor configuration changes and updates resulted in VM outages. Now, downtime is dramatically reduced."
"The ROI is great on this product."
 

Cons

"Enhanced documentation and beginner-friendly guidelines would benefit users with less configuration experience."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"They could improve the price."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"One improvement could be incorporating a feature similar to Dropbox's version history. This would allow users to track modifications made to files over time, which is particularly important for maintaining a record of changes. While the free version might not include this feature, it could be included in the paid version to provide added value to clients. Additionally, having a version history feature that allows users to access modifications made to files over the past three months could be beneficial."
"If I had to choose one area, it would be making the consoles more intuitive would be helpful. Sometimes, they can be a little complicated if you're not familiar with them."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"IBM Cloud storage is not cheap, but it could be."
"The performance could be better. It isn't bad, but everything is network-based, so you have a performance penalty on the network. You can never achieve the same performance as hardware. That's the disadvantage of cloud storage solutions in general. Cloud performance is one of the main issues clients have."
"IBM has limited cloud storage."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"Room for improvement depends on customer needs. Some customers prefer pure Object Storage using the S3 protocol, while others use a gateway in front of the storage grid to enable CIFS or NFS."
"They recommend RAID10 for HDD, which reduces the usable storage capacity."
"Being able to run StarWind vSAN on top of any free UNIX operating system to build a resilient iSCSI/FTP/SMB storage system would be useful."
"It would be great if the Linux version of the management console offered the same features as Windows."
"A better overall view of the different deployments could be beneficial, although this is difficult due to how flexible the solution is."
"The initial setup got a little confusing at a few points with differences between the VMware version in documentation vs the latest, etc."
"High availability for direct attached hardware drives (without virtual disk layer) could be useful to increase the performance of StarWind virtual storage cluster."
"I think the setup could be streamlined a bit."
"The most disappointing side of the application is the free edition. There used to be GUI attached. That has recently changed to only CLI management of the application."
 

Pricing and Cost Advice

"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"I would prefer that they lower their pricing."
"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."
"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."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"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."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"Like most cloud providers, IBM likely charges based on storage capacity, typically per gigabyte or terabyte. Their pricing is competitive when compared to AWS or Microsoft."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
"You have the option of a monthly or yearly license. Most customers choose the monthly option. I understand what you would like to say. IBM also lets you choose among four types of Cloud Object Storage. The difference is usage, performance, etc. Of course, high-performance storage is more expensive, while low-performance storage is for cold data, and it's really cheap."
"Pricing is not cheap."
"The premium support from StarWinds is a must have. The ability to have access to a storage engineer 24/7 is a must for a production environment."
"We are happy with the price."
"Licensing is based on nodes rather than TBs, which means that the users are free to increase storage capacity without putting thought into licensing."
"The pricing is more than reasonable."
"I think the bang for the buck is much better with StarWind Virtual SAN."
"The licensing is straightforward, with free and trial versions available."
"The cost was ultimately low to implement, which allowed us to be 3-2-1 complaint."
"I would suggest that you download the free version, deploy in your lab, and play with it."
