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's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done."
"It makes things ten times easier."
"The features that are there now are really what we need."
"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."
"The compression and deduplication features help to make the best use of the capacity."
"The most valuable features I have experienced are the centralized management and redundancy under speed of the right disk."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"The solution has 100% storage availability and we've had that for more than ten years."
"SANsymphony-V offers a comprehensive set of storage virtualization functions to build a very robust storage network that speeds up applications, ensures business continuity and facilitates disaster recovery."
"It is a well-proven, automated management tool in all dynamic provisioning, auto-tiering, great performance, parallel I/O​, cache speed mechanism, etc."
"The most valuable feature for us is that we can adjust the size of the storage very easily, without stopping production."
"DataCore is very fast storage, applications start faster, and database access is improved."
"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."
"For us, fault tolerance is the most important feature of DataCore."
"DataCore has been doing software-defined storage since back before SDS was even a buzzword, and it has provided a great deal of flexibility, performance, and efficiency for our Enterprise SAN."
"The best part of the solution is that you can actually scale up to a large number of operating systems without the requirement of additional hardware, which is the biggest advantage."
"VMware Software Defined Storage gives higher availability against data corruption."
"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 technical support is awesome."
"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."
"The solution is simple to configure and provides good performance and less footprint."
 

Cons

"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."
"One improvement area is the eradication time delay."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"The product should improve its response time. I have also encountered issues with its configuration."
"Self-backup is the only feature lacking in this solution."
"Going forward, don't complicate things for the customers."
"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."
"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."
"I found it a little unnecessary to have to rename the configurations within the graphics console in order to have unique names."
"The solution could be better packaged and marketed."
"NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future."
"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."
"I think an easier way to open a service call, right through the DataCore GUI, would be an improvement, especially when there is an urgent issue."
"In my opinion, there should be improvements in how to get and filter logs."
"The alert system could have more features."
"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."
"It's easy to scale and expand but the main catch is the cost. It's expensive."
"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."
"There is room for more integrations and plugins into more storages."
"Simplifying the licensing model and making it cheaper would improve the solution."
"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."
"I'd like to see improved hardware compatibility"
 

Pricing and Cost Advice

"We purchased a license to use this solution and we pay for the storage ourselves."
"Pricing is very competitive, and it's better than other competitors."
"It's priced higher than the market."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"There are no licensing fees aside from the support."
"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."
"Its price is almost double than any other flash storage solution."
"Make sure you are made aware of the annual subscription cost when purchasing."
"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."
"The pricing and licensing are better with DataCore."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"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 cost is at the same level as other storage solutions and it is easy to understand the licensing."
"Pricing has improved but it is still 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."
"VMware Software Defined Storage is a slightly expensive solution."
"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."
"The solution is very expensive."
