Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration.""Performance, deduplication, compression, and fast response time for requests from servers and applications.""NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support.""It's easy to use, and the maintenance upgrades to get free controllers work really well.""The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions.""I never have to worry about its performance or if it is the root cause of an issue.""The most valuable feature of Pure Storage FlashArray is its high stability level.""The speed is one of the most valuable features of Pure Storage FlashArray."

More Pure Storage FlashArray Pros →

"The solution is very user-friendly in terms of maintenance and configuration. It's also possible to connect the solution to other storage management solutions.""The deduplication is useful for us because we don't have that much money for our lab infrastructure. Deduplication means we have more storage available. And the IOPS are really fast.""The solution provides excellent scalability.""The active-active option seemed to be working well and overall, it was a solid product.""It's a state of the art solution in storage systems. High-availability and performance are the strongest aspects of these machines.""This is one of the most reliable and dependable products on the market.""Overall, the solution is strong, easy and fast.""The most valuable feature is that it has 'eight nines' availability, 99.999999 percent of the time. That is the main selling point."

More Hitachi Virtual Storage Platform Pros →

"It runs. I don't have a problem with it. If it needs an update, I can do it in the middle of the day with nobody being the wiser. It is phenomenal in that respect. As a hospital, I get two hours every quarter to reboot things, so it is imperative that nothing goes down.""Remote-copy provides high availability and disaster recovery for the connected clients.""It allows us to cohost as needed. We are able to put more systems on one data storage system and it is still able to deliver the availability and speed that we need it to deliver.""We use for our tier one and two apps, so they can do failover, synchronous replication.""We like something called Virtual Volumes and how we can do thin provisioning.""It is very stable. That is why we bought it.​""Its stability is the most valuable. It has soft alerts. When an alert is raised, we get a call from HP saying that there is this type of alert, and they need to do a remote session to check things. Similarly, for firmware updates, they get in touch to say that a firmware upgrade is required on your storage. They schedule a time and take control remotely to upgrade the firmware. In all such cases, there is no downtime. Everything is done when a full-fledged operation is going on. Its user interface is also quite good. We are quite accustomed to this user interface. We can easily take a look at the current usage or the amount of storage. It is quite easily understandable, and I can present those things to my seniors or other people who are not that tech-savvy, and they can easily understand what we are trying to tell them. We can easily show them that we are using around 87% of the storage, so we need to plan for another tree and things like that.""The most valuable features for me are the simple management of the platform and its performance."

Cons
"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case.""There was some complexity in the initial setup.""Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing.""It is not possible to create a cluster on top of multiple arrays.""We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter.""The GUI could improve, it could be more intuitive. There is hidden functionality.""I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable.""If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."

More Pure Storage FlashArray Cons →

"This product should be easier to install and set up.""It seemed like every time we turned around it was a statement of work and we'd have to pay for something that our previous vendors would not have billed us for.""The solution is priced higher than its competitors.""The embedded management for installation feature has neither simplified nor complicated the management process, therefore, there is room for improvement.""The initial deployment was somewhat complex when it came to the installation because of the network connectivity. It was more difficult, in this specific case, than with other platforms.""The snapshot and clone operation functions can be made easier.""For the support windows to work, maybe they have to upgrade the firmware of the VSP. They changed the hardware or the disk. I don't know if it was the port blade they changed or a VM for a memory cache. Also, replacing the old target with the processor target would be fine. The old equipment is very easy to manage, and I don't have any bad commentary.""n future releases, I would like to see enhancements in the web GUI capabilities for direct management without additional PCM."

More Hitachi Virtual Storage Platform Cons →

"Sadly, the support from HPE has not been all that great. It is tough to get a tech out or get a response from some of the techs that we have.""The replicating software is pretty complicated. I probably would have put it on a sequence.""The speed of the hard disk could be better. The performance is the main issue for us. The performance of the VMs is not comparable to desktop machines, for instance, and we might need another solution to improve the performance. Other than that, we don't have any issues. We already have a great part of storage with SSDs, and the performance is not as good as I expected.""We need longer names for our volumes. Now it's only 28 characters. It should be 64, or at least more than 32 characters.""I would like to see an automatic re-balancing system or functionality for adaptive optimization.""HPE could improve by raising awareness when a new product is launched. They must think of ways to better serve and engage with their enterprise customers. HPE is selling enterprise products and mission-critical support.""While the stability is pretty good, it could always be improved upon.""This solution is now at end-of-life."

    Anonymous User
    Leading up to EMC World 2015, IT Central Station asked how I would compare EMC XtremIO and HP 3PAR. Until recently, the flash storage conversation in my organization and many others has centered on XtremIO and Pure Storage, the leaders of the all-flash array (AFA) space. To that end, I've written a few posts already. In 2015, though, the HP giant began to rouse and challenge the mainstream status quo with its 3PAR offering. Quantifying 3PAR's platform is different from XtremIO and Pure, though, as it can seem amorphous given the many ways it can be quoted. Are you asking for all flash? 3PAR will give you that and lay claim to the best-of-breed title. Oh, but you want some mass storage akin to archival or virtual tape, too? 3PAR changes jerseys and shouts, "I'm it!" Is it, though? Let's put 3PAR against XtremIO and see how they measure up! Define the Conversation  The hard part about these comparisons and competitive analyses is that we aren't talking about products of the same species or specialization. I struggle to put it properly, but consider it this way. In pre-AFA days (the age of traditional spinners like NetApp FAS3040, EMC CLARiiON or VNX, and even last-gen 3PAR), the contest was like pitting a Toyota Camry against a Nissan Altima. They did most of the same things with minor strengths, weaknesses, and preferences. Talking about XtremIO versus 3PAR 74xx is more of a discussion about construction-grade, heavy-duty cranes versus massive earth movers. They are in the… Read more →

    3PAR is SAS-based storage. The industry is already moving away from the 35-year-old SCSI-way, so it's not a good idea to buy any product with it. 


    I'm not sure about Hitachi, but as far as I know, they also have SAS backend, so, the obvious answer to the question "Which should I choose?" is "none of them". 


    My recommendation is - choose other vendors (or models) which provide end-to-end NVMe support and make a choice between them.

    Hitachi, if cost and performance for mission-critical apps are high priority. 


    Otherwise, HPW 3PAR (or now HPE Primera) will be the best all-around for cost and performance. Plus, HPE's Storage Insight is the best on the market

    It depends on what kind of requirement you will use with this All-Flash Storage Array. 


    Usually, high random IOPS is a must for AFA, however, recently there are more and more requirements that are talking about low latency as the key in the virtualization environment. So if you would like just for high random IOPS and MBPs, considering the SAS SSD AFA will be enough, but if lower latency will be your major impact in the environment, NVMe AFA will be the best.

    NImble Storage from HPE or Primera, Hitachi sold their disk division. HPE 3Par will be announced soon as the end of life. 


    Instead, Primera has been created (Primera has the best from Nimble and 3Par). I hope it helps.

    I think that you need to meet the needs looking to the best fit to your environment. Looking into Hitachi Vantara portfolio, you will see entry level storage to enterprise. At my point of view, performance, reliability and scalability should be considered.


    Another consideration above performance (IOPS and latency), you must to provide the correct profile, such as block size, random or sequencial data, cache hit, replication and snapshots needs. All those informations provides a better solution for your environment. 


    Dont you forget about the scalability, I think that you must to know how you are growing to fit the best equipment.

    Hi, 


    Just assess Pure Storage box as well and also if you are focusing on some specific workload do mention it while discussing with the Pure Storage team like OLTP, DB(SQL/Oracle) or any platform service, etc. At last, your budget is also a major factor while evaluating. As all Flash Arrays do cost more.

Additionally, it offers users quick memory read and data access speeds.

    • A higher bang for your buck in terms of the storage capabilities you get for the money you pay. They are smaller in size than more standard storage technologies, but they offer flash memory, which enables users to store larger amounts of data than the current standard.

    Reviews from Real Users

    Pure Storage FlashArray is a highly effective piece of storage technology which stands out among its competitors for a number of reasons. Two major ones are its overall robustness and the value that it offers by way of its reliability and ease of use. It provides users with many valuable features that allow them to maximize what they can do with this solution. Pure Storage FlashArray’s reliability and ease of use make it a highly valuable solution. 

    PeerSpot user Prabakaran K., a technical consultant at Injazat Data Systems, notes the robustness of this solution when he writes, "FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."

    PeerSpot user Jason D., a cloud solutions architect at a tech services company, notes three features that make this solution valuable when he writes, "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."

    Reviews from Real Users

    Below are some reviews and helpful feedback written by PeerSpot users currently using the HPE 3PAR StoreServ solution.

    A SAN Consultant at a tech services company says, “One of the features that I like the most is the data replication element. The reason I like it is due to the fact that it's pretty clean on replicating data over to a second site. The product stands on its own in heavy enterprise environments. It's easy to make changes without affecting the environment. The solution is very easy to use. The product is very robust and offers very good performance.”

    A Storage Manager at a financial services firm mentions, "There are a lot of screens for easy management where you can change some settings. But after a few years, the important settings were better after an upgrade, and all the vendors have other ways to upgrade their systems."

    A Senior IT Infrastructure & Data Center Operation Engineer at Ministry of Communications and Information Technology (MCIT) comments, “The adaptive optimization is the biggest feature in 3PAR. 3PAR is very usable with thin volume because it detects zeros while writing. Every time I tell the hypervisor to make the full provisioning, it makes the volume as simple provisioning in 3PAR, not full provisioning.”
