Pure Storage in Mountain View, California offers all-flash array data storage promising affordability, high availability, and consistent performance.
Due the corporations history of using Dell solutions, Dell EMC Unity fit in perfectly with the corporations technology strategy. It also was comparable to other solutions in terms of performance and reliability. The support was also exceptional.
We were directed to buy these arrays and didn't have the ability to evaluate the other arrays. Once we evaluated the other products in the market that compete with Unity we saw that the younger, more built from the ground up arrays, had much better features, software, and ease …
Really the deduplication and compression ratio has been all over these guys. The speed on the flash storage seems more customized if I may say and our deployments were smooth. Nothing against these guys since we work with all at the same level, but there are very notable perks …
The ease of use was the best part. Even the more modern versions of Dell EMC still had the "old school" way of dealing with things. I did not need a Pure engineering team to come out and install the array like I would have needed with EMC.
The FlashArray is faster and easier to use than all the other products I've used. Other ones are close, but from our perspective, Pure won in every area.
FlashArray beat the Unity in every single test I made! The Test result for the Unity was so bad that EMC sent 7 technicians/salesmen to check our test results. Even with specialized firmware, they can't nearly reach the Result of the FlashArray.
Nimble storage could not be clustered like Pure, Simplivity was completely converged so if one aspect of the design was under-specified it would require a full new node, Netapp only offered clustering with a special cost licence, whereas with Pure all functionality upgrades are …
Pure Storage blew everyone else out of the water in terms of performance, ease of use and setup. Getting a PoC unit allowed us to fully test the array with our own workloads, and fully vet that it would stack up. No other provider was able to give us this comfort!
Our Unity 300F was horrible and had we even been able to POC it, it would have failed but it wasn't our call. EMC support used to be something to be proud of (think 2011 before the Dell purchase) but has become the butt of many MANY jokes. The PURE Storage system is better in …
Dell EMC Unity is an easy system and very flexible component and very easy to navigate while providing effective services and management of multiple project information management and the data pulling from the supported third-party platform is easy and quick. Excellent reporting features and easy to use and the analytics tools are amazing.
When you need speed, it's FAST, especially for MS SQL databases. If you are having bottlenecks, you can spend your time finding it in the code because it's not Pure Storage. Love the data reduction and duplication. We can store so much more on this unit than the base physical size. Love the data snapshots. When you need to complete copy your entire environment for testing etc. Nothing is easier, a few clicks and you are done. Extremely helpful for testing and training.
Alerting: receiving an alert when an issue occurs. That is good to know. However, if the alert is cleared, or somehow no longer in alarm, no email is received. At times I will receive the email alert on weekends, not knowing if the issue is resolved or not until Monday when I can access the unit. I have learned in most instances, the alert is a false alarm, which could be a problem.
The alerting itself is sometimes not clear. For example, it tells me the link is down, we reset the connection, the link is still down, a tech was dispatched, he troubleshot, and finally the alarm cleared. This incident took almost a week. It went back into alarm after he left, then suddenly it cleared on its own.
Reporting is too general. Being a tech nerd, I want to be able to see the nitty-gritty details. I also need to be able to define canned sets of reports for problem application systems.
Pricing is a bit higher then some of their direct competitors .
It has so far been a very fast and stable product. We have had wonderful support when we have needed it and the account manager and engineer attached to our organization have been very responsive with any questions and concerns we have had.
From the day our first array was put in (2017) we have had very little issues using it the way we wanted to and none of the setup or processes we incorporate this into have ever been complex. All of the interfaces in the GUI are very intuitive and do not require any CLI experience to do what we need it to do.
We have never had an outage with Purestorage. Yes we have had 2 drives go out but replacements were installed so fast there wasn't any issues. We have had a NVRAM module replaced but were noticed from Pure they were sending a replacement because they were predicting a failure so pure was proactive preventing any issues. Knowing Pure is monitoring our device 24x7 gives us peace of mind.
The corporation has a very diverse data load and when we migrate from a hybrid storage to pure all-flash, significant gains have already been observed. Latency always remains below 1 ms regardless of the load and volumetry used. Application performance also depends heavily on whether or not the code is more permormatic and network access infrastructure. The product has been meeting expectations
Not only support for Unity, but for any Dell product, whether for companies or for the end consumer. Support is agile, helpful, and always focused on solving the problem. To date, there has been no problem that Dell's support has failed to resolve and help us with.
Pure Support is timely and communicative. They are always ready to assist and very skilled at what they do, no matter the time of day. Even at 12:10 a.m. on New Years Day when your array has a hiccup that causes some errors in your environment, they will be on the phone with you in an instant. If they are unable to determine the cause right away, because things appear to be normal, they will take your environment's configuration, lab it up in their support environment and then research until they figure out what caused the problem. Even if it takes 3 months. True story.
Excellent training and really you don't need that much. We received training at the Pure offices and also on site when the product was installed. Simple things like how to login to the GUI interface, how to setup users, how to create volume and mount it. How to make a snapshot, how to copy it and mount it. Really is pretty self explanatory on how to do things with the GUI interface. We were expecting complicated base on other vendor products, we got super simple.
Great videos and documentation. There is a common theme with PureStorage, "Keep it elegantly simple". They have great support network and great support user groups. Documentation has been very helpful with providing auditors with methods and procedures on security and other ways the product works. Great documentation on setting PureStorage to be the most effective with VM's, SQL Server, and other products.
I was instructed to buy these arrays, but I was not given the opportunity to evaluate other arrays. We evaluated other products in the market that competed with Unity and found that the younger array built from scratch had far better features, software, and ease of use. The Unity system has a unique way of storing the data when compared with other systems.
Pure Storage FlashArray came up as being the most cost-effective of the lot plus the extras added like call-home support were very welcome. The competitors' options were a lot more expensive and the call-home support added a lot more to the already high costs.
Thanks to the deduplication that is built into the product we are seeing great reduction in total space required by consolidating similar data types on the same array.
Our users are very pleased with the performance.
The replication allowed us to move our workload from to another data center with minimal downtime.
