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.

Storage platform has improved data performance and has provided reliable support for my clients
It's difficult to know how DataCore SANsymphony can be improved. I think DataCore SANsymphony could be deployed on Linux environments, which could be a great thing for clients. I would like to see the stabilization of the Veeam implementation in the future, and perhaps the integration or officialization of compatibility with Proxmox and XCP-ng. With Proxmox, it wasn't easy while integrating it with third-party solutions. It's working, but it was a bit difficult to deploy.

Quotes from Members

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

Pros

"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"The solution offers amazing performance."
"I have never experienced an outage with the product or had any support that was below excellent."
"The stability of Pure Storage is very very good."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"The code upgrades are very smooth."
"It is an easy to use product for all of my team members."
"It saved a lot of space, as far as physical space in our data center."
"Cluster maintenance is super easy: just add a node to the second site and the software takes care of the data."
"The dashboard is very intuitive, and there are many counters to diagnose what happens during a short period (like when a backup is in progress)."
"The better features are the synchronous replication and the management console."
"The support is excellent."
"The solution has 100% storage availability and we've had that for more than ten years."
"It is a stable solution."
"It's a software storage solution that can scale as we like. There is also has a parallel feature that enhances the performance of the storage solution. We can separate storage and computing, and we can scale these two parts of the platform to meet business needs efficiently."
"DataCore gave us speed, redundancy, reliability, and works great with our backup system."
"This is an easy-to-use product for adding flexibility to your storage solution."
"The product is user-friendly from an administrative standpoint and very easy to use."
"The most valuable features of the solution are that it is easy to deploy and the support is really good."
"The solution is simple to configure and provides good performance and less footprint."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
"The single management panel is the main feature that is wonderful for the customer."
"VMware Software Defined Storage gives higher availability against data corruption."
"The technical support is awesome."
 

Cons

"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."
"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"It doesn’t provide enough information on performance analytics. For example, Nimble Storage has Infosight, which provides data; Pure Storage doesn’t have an equivalent."
"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"Regarding documentation, it would be helpful if we could have access to the root passwords for administrative tasks."
"The system has dual controllers but does not have a high level of resiliency built-in."
"I would like for it to improve into a more ergonomic management console and a translation into the French language. It should have some process for a shutdown of a VM properly in case of a problem."
"We are waiting for container support (on the roadmap), as well as a user-friendly full web-administration capability, and an improved API."
"The so-called hyperconverged infrastructure edition, sometimes known as vSan, should be addressed."
"I think the performance reporting can be improved by adding historical statistics into a database for the purpose of comparison."
"DataCore should integrate its own file server into SANsymphony."
"For customers or technicians that don't speak and understand English, it could be great to have other languages support, all the more so given the number of countries in which SanSymphony is used."
"Unified storage (all block, objects, and files) should be in a single storage pool with unified storage concepts, hence providing the user with whatever they want."
"The heavy client mode console should be improved by having a web console to improve accessibility."
"The cost of the product is where an improvement could be made. It's generally very expensive and requires a lot of architecture that needs to be designed according to specific situations."
"I'd like to see improved hardware compatibility"
"It's easy to scale and expand but the main catch is the cost. It's expensive."
"It doesn't have the ability to be deployed on any kind of hardware and network connectors."
"Simplifying the licensing model and making it cheaper would improve the solution."
"The performance is not as good as some competing products and reporting can be improved."
"VMware Software Defined Storage should include a shared database on a standard version."
"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."
 

Pricing and Cost Advice

"The price, in general, is around $100,000, however, I know it costs more."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"Pure has been flexible with us on the pricing models."
"There are no fees for licensing. The hardware is paid for only once."
"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."
"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."
"Cost-wise, it's been very effective."
"There are no licensing fees aside from the support."
"Make sure you are made aware of the annual subscription cost when purchasing."
"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."
"Pricing has improved but it is still expensive."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"The cost is at the same level as other storage solutions and it is easy to understand the licensing."
"The pricing and licensing are better with DataCore."
"The solution is cost effective."
"This product has a good ratio between quality and price. In many cases, it's less expensive to work with DataCore than other storage systems."
"The product is quite expensive and is among the most expensive for this type of solution."
"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."
"VMware Software Defined Storage is a slightly expensive solution."
"The solution is very expensive."
"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."
