Sowjanya MV

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.

Operates seamlessly and minimizes downtime while meeting enterprise file share demands

The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed. These features benefit my company by providing less downtime and less overhead. While I have not calculated an exact number regarding the reduction in downtime, we have always been using the product, so we have no baseline to compare it to. However, it is a very good product. Dell PowerScale (Isilon) scales very well with the growing needs of my company.

Rifat Rahman

Infrastructure Architect & CEO at Tirzok Private Limited

Offers reliable performance and availability for large deployments

I would like to see improvements in Red Hat Ceph Storage not because I necessarily think it needs improvement, but because I generally prefer to do things manually rather than following the containerization part. Current deployments are based on containers, but I deploy manually with my scripts and controls. If there are no Kubernetes-like requirements, I often prefer to deploy a whole manual process. I don't ask for improvements in the deployment model because Red Hat has its own philosophy about making things, but it's my personal choice that I prefer things manually. Some features are available only in the containerization part, so if those are also available in manual deployment, that will help.

Quotes from Members

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

Pros

"The initial setup was really straight forward."

"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."

"FlashArray's data reduction and NAS features are incredible. Its performance is the best I've worked with."

"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."

"The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."

"It is an easy to use product for all of my team members."

"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."

More Everpure FlashArray pros

"The solution in general has allowed us to move off of multiple Windows boxes where they had huge data stores, and we migrated it to the Isilon, making it easier and more cost-effective with just one point of contact."

"With Dell PowerScale (Isilon), it uses not just a terabyte but petabytes of data, storing a large amount of data takes within minutes, and you can bring it down to seconds as well, as it does not take much time to upload or copy the data here and there, and upgrades also do not take much time."

"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."

"I buy Dell PowerScale (Isilon) because of the price, service, and technology, and the technology that is particularly good for my company is that I have two Dell PowerScale (Isilon) systems in two sites, and I use replication between them with Superna software, which is a third-party Dell technology."

"My experience when deploying Dell PowerScale (Isilon) was very straightforward, as we had Dell come on site to do all the actual setup, which was a big help."

"Dell has been great with everything."

"There are also the policies that you set up on replication and purging files, and policies for something called WORM. That's a "write once, read many," where you can't overwrite certain files or certain data. It puts them in a "protected mode" where it becomes very difficult for someone to accidentally delete. We use that for certain files or certain directories, because we're dealing with video and some video has to be protected for chain-of-custody purposes. The WORM feature works great."

"The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once."

More Dell PowerScale pros

"I can compare Red Hat Ceph Storage with products from other vendors; I explored quite a few, but I still find that Red Hat Ceph Storage is making the most disruption."

"It opens doors for completely open-source cloud."

"Red Hat Ceph Storage is a reliable solution, it works well."

"We have not encountered any stability issues for the product."

"We have some legacy servers that can be associated with this structure. With Ceph, we can rearrange these machines and reuse our investment."

"It has helped to save money and scale the storage without limits."

"Red Hat Ceph Storage is working exactly as it should be; it's running in the background, it's working, and it doesn't bother me."

"radosgw and librados provide a simple integration with clone, snapshots, and other functions that aid in data integrity."

More Red Hat Ceph Storage pros

Cons

"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."

"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."

"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."

"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."

"The interface lacks the same level of control as some other arrays I've used."

"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."

"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."

"I would like to see box-to-box encryption on replication included in the next release."

More Everpure FlashArray cons

"Dell PowerScale can improve on its multi-tenant part because as a service provider, we have bigger clusters in data centers where we can serve multiple customers and grant them dedicated management points and automation features that can be managed in a multi-tenant environment."

"It is a bit higher priced than some of the other systems."

"The product itself is capable of very much, but the initial deployment experience can be lacking possibly because it does not incorporate any design phase."

"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."

"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern."

"My experience with customer service and technical support has been challenging. The reason is that it is difficult to find subject matter experts around the solution."

"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."

"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."

More Dell PowerScale cons

"Areas of Red Hat Ceph Storage that have room for improvement include more promotion. Many people do not know about the Stratus case, which is one of the most reliable systems available in the world, but they are not aware that a system can keep working even if there is a hardware failure."

"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."

"This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing."

"I have encountered issues with stability when replication factor was not 3, which is the default and recommended value. Go below 3 and problems will arise."

"While the documentation for Ceph Storage is helpful, it could be improved."

"In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures."

"What could be improved in Red Hat Ceph Storage is its user interface or GUI."

"We have encountered slight integration issues."

More Red Hat Ceph Storage cons

Pricing and Cost Advice

"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."

"It was less expensive than some of the alternatives. It's not as though it was a premium price to get that kind of quality. It's a very competitive product from a price perspective..."

"The price is reasonable."

"We have seen a reduction in total cost of ownership (TCO)."

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."

"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."

"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."

"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."

More Everpure FlashArray pricing and cost advice

"The pricing for this solution is reasonable."

"The solution's licensing cost varies based on capacity and performance requirements."

"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."

"It is an expensive product with a high storage capacity suitable for large data requirements."

"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."

"Dell PowerScale is an expensive solution compared to other products like Qumulo."

"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."

More Dell PowerScale pricing and cost advice

"I rate the product’s pricing an eight out of ten."

"There is no cost for software."

"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."

"If you can afford a product like Red Hat Ceph Storage then go for it. If you cannot, then you need to test Ceph and get your hands dirty."

"The price of Red Hat Ceph Storage is reasonable."

"We never used the paid support."

"The operational overhead is higher compared to Azure because we own the hardware."

"Most of time, you can get Ceph with the OpenStack solution in a subscription as a bundle."
