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 Manager at MSDSYSTEMS S.R.L.
Has simplified data protection across two locations and reduced time spent on recovery efforts
The best features DataCore Swarm offers are its scalability and the ability to truly solve many problems related to data loss and recovery. It is important because if we want to add a new code, it sets itself up from scratch, and if we want to add, for example, a 72 terabytes or petabytes node, we just drop it in, which is very easy. DataCore Swarm has positively impacted my organization through the support for my dedicated salespersons.
Amarnath Charugundla - PeerSpot reviewer
System Engineer at Tata Consultancy
Unified management and cost-effectiveness lead to positive experiences and future savings
Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.

Quotes from Members

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

Pros

"Performance is the most valuable feature."
"Technical support has been amazing."
"I like the performance. Performance-wise, it accommodates the needs of highly-critical servers. It is reliable."
"I have seen a huge increase in speed and performance on our databases."
"Its array houses our entire production environment."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"We have integrated the solution with VMware, and the process was seamless."
"Technical support is good."
"The first feature is compatibility with the S3 protocol. DataCore SWARM allows you to quickly have an on-premise, robust and scalable environment that is natively compatible with the S3 protocol. The functionalities used are therefore derived from the S3 protocol, notably versioning and therefore the possibility of configuring immutability in governance or compliance mode. The object metada can be enriched with the addition of tags to subsequently enable filtering and searching. Configuring and using DataCore SWARM is simple and flexible. It is very easy to create domains, tenants and buckets for different use cases with various authentications. The cluster architecture also allows replication between different clusters at different configured levels (Cluster / Domains / ...) A web interface for browsing the content of existing buckets allows simple and rapid manipulation of certain objects such as sharing via a link or cropping a video. Finally, the physical architecture of the solution is based on an x86 server and its scale-up or scale-out evolution is very simple by adding disks or servers."
"DataCore Swarm is highly available."
"I find its flexibility valuable, it's also user-friendly, and I'm happy with the dashboards and the customization."
"The ability for the solution to use any new hardware quickly and without administration is a great thing in the context of hosting."
"I find its flexibility valuable."
"The best features DataCore Swarm offers are its scalability and the ability to truly solve many problems related to data loss and recovery."
"With DataCore Swarm, we have transitioned from tape-based backups, which were long, to Swarm, making the process more rapid and efficient."
"Some of the features that we use include replication and snapshot capabilities, especially from remote locations to our data centers. The main benefit our company sees from using Nutanix Unified Storage is simplification. In the past, we used three-tier solutions with a lot of complexity and operational overhead. Now, we want to focus on the layers above. I want to have storage available, but I don't want to have to think about it. I want it to work without any issues."
"Nutanix is totally reliable and very stable, it operates 24/7."
"The solution's most valuable feature is the Prism Central centralized management console."
"Nutanix Unified Storage does a very good job of unifying our organization's block, file, and object storage. It puts it all in one place. From one platform, we can deploy S3-type buckets. We can provide iSCSI-level block storage if we need to. It does a great job with home folders and departmental shares, which is what we mostly use Nutanix Unified Storage for."
"The performance has been very good."
"The best features of Nutanix Unified Storage (NUS) are its excellent performance; comparing it with other vendors, there's no need for expertise as with other storage solutions."
"The solution is stable and extremely easy to calibrate."
"The most valuable feature is the easy interface."
 

Cons

"The best way to improve Pure Storage FlashArray is the active DR because that can get very confusing, especially when you're trying to test a failover and replicate back; better instructions on how to do that would help because we actually lost an entire volume when we were testing out some stuff as the fingerprint got reinitialized, and when you replicated back, it didn't know about that volume, causing a failure in that process."
"The negative aspect of Everpure FlashArray is that migrations can be somewhat complicated."
"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."
"I would like to see more cloud integration."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"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."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"The pricing can definitely be better."
"The product currently requires a significant number of servers to start. There are also network prerequisites to be met in order to guarantee good security of the architecture, which means that the product is only available to large customers. Besides, the license starts at 100TB. An Appliance version is being developed with an architecture based on containers which will make it possible to offer DataCore SWARM to everyone. The product has been evolving since the acquisition by DataCore, but maintaining and updating the product is not always easy and needs to be improved. For now, we only use DataCore SWARM for a few use cases and therefore a small part of the existing functionalities. With use we will perhaps have more criticism of the product but not for the moment!"
"The main issue currently is the hard installation process."
"The solution needs simpler architecture."
"We have some problems with Nutanix Unified Storage's support because they asked us to change our hardware."
"I think Nutanix Unified Storage (NUS) can be improved with integration with vendors other than VMware or Dell, seeking more integrations with other storage vendors."
"The licensing terms are restrictive, as they go by terabyte cost."
"I hope Nutanix Unified Storage (NUS) will improve the clarity of the licensing uses and enhance the reporting and analytics, which are not sufficient."
"Since it's part of Prism, I might suggest integrating the management console into Prism instead of having a separate console; that's the only change I would recommend, and it's not a significant issue."
"It's still pretty expensive."
"A centralized file share permissions console might be useful for Nutanix Unified Storage (NUS). Getting in and directly managing permissions instead of using the snap-in from Windows itself might be something to consider, but that's a small thing."
"Its features can be further enhanced from the DR and high availability points of view to match other vendors, such as NetApp. It has snapshot, replication, high availability, and other data and storage-level replication, but there are some limitations."
 

Pricing and Cost Advice

"We lost a lot of customers because we couldn't compete on price with other vendors."
"Because of the SSD, it is cheaper because I am not purchasing so many disks."
"The pricing of Pure Storage FlashArray is reasonable."
"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"The licensing is $100,000."
"There is always room for negotiation."
"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."
"We have an Evergreen Storage subscription, which I think is a great feature."
"The first installation brick is expensive but the upgrades are extremely simple and granular by adding disks or nodes."
"You pay for what you use. For example, if you use one terabyte, you just pay for that one terabyte. But the pricing could always be better"
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"It's definitely a lot cheaper than buying a new EMC array. We bought a five-year commitment on all the hardware and software. I don't know what the cost was back then, but I do remember it was cheaper."
"In my opinion, the product is fairly priced."
"Nutanix is very competitive."
"Compared to other solutions, NUS is cost-effective and efficient. It also has good performance."
"I am not the one who makes the calls, but it seems to me that it was very competitive. Other solutions would have required dedicated hardware, so an additional CapEx has to be put in place. In that sense, it was definitely a more competitive option to go with Nutanix Files."
"I find Nutanix Files Storage competitively priced, even its feature set. Its price is seven out of ten."
"It is not too high for what we are using."
