The NetApp® EF-Series is a family of entry-level and midrange all-flash storage arrays that accelerate organizations' access to data and help derive value from it. These systems offer NVMe flash storage and provide more affordable to extreme IOPS, boasting response times under 100 microseconds and bandwidth up to 44GBps.

NetApp acquired the scale-out flash storage startup SolidFire in late 2015. The product line was discontinued in October of 2023, and is no longer available from NetApp.
NetApp EF-Series All Flash Arrays is useful for the application that required high badwidth , IOP's like Video surveillance, analytics (hadoop), online transaction processing applications, fast data backup and restore. NetApp EF-Series All Flash Arrays is less appropriate for the application that required low/medium IOP's . i.e log collection application server, snapshot collection ... etc.
Solidfire is a good, multi-purpose array for iSCSI environments. Grid architecture allows incremental, linear expansion of the array both in capacity and performance. The all-flash is a very high performance, low latency platform for a lot of applications. The way the company has architected the platform allows for continual upgrades and removes the lift-and-load replacements if you stay with Solidfire in the future. The Solidfire fiber channel implementation is workable, but largely there is a checkbox. I cannot imagine any fiber channel shop is going to look at a Solidfire seriously, unless they are looking to move towards Ethernet based transport. Write intensive workloads struggle on the array. The double-helix data protection combined with the architecture can make writes more latent than expected - well into the teens and 20's of ms within the array.
When we have had problems, the response on the Solidfire side has been strong, but not perfect. As they scale and integrate into NetApp, support from regions outside of the USA are having a more difficult time diagnosing and addressing issues for complex problems. The Boulder, CO, and Raleigh, NC, support teams are both extremely strong and provide top-notch support. ActiveIQ is a great support tool both for NetApp/Solidfire and for the customer. The proactive support tickets opened have been helpful. The node-based support has been excellent - meaning when we had a DIMM fail, they sent a replacement node - no time consuming troubleshooting of internal components to fix the issue. Upgrades are handled by SF technicians, so it feels white-glove
I have not been able to work with such a great platform in my career experience. Data storage and networking of all databases have been a great achievement of this platform. The user interface is simple and the dashboard shows clear trends in data infrastructure. There are backup storage systems on our cloud servers in case we lose any data. It has an automated update system that keeps our applications up to date.
SolidFire was chosen over these other service providers because of relationships we have with the company, with our reps, and with the local Denver presence. We also are a partner, and we felt that the solution stacked up technologically very well against the competition and was more cost effective.
