Dell (EMC) and NetApp dominate the all-flash storage array market, having overtaken Pure many years ago, and they have been my focus for many years. I have worked with EMC storage going way back to the days of the CLARiiON CX300, about 15 years ago, through to this year’s release of PowerStore – it has been an interesting journey to see the product evolve overtime.
I started working with NetApp about 10 years ago, around the time they were transitioning from 7-Mode to Clustered ONTAP. This was a challenging time for the company as it took many years to migrate all the features, but once this was complete NetApp evolved ONTAP into a very powerful solution.
Let’s take a quick high-level look at how their latest all-flash offerings compare:
Dell PowerStore advantages
- Very simple to deploy and manage
- Dynamic Disk Pools and a single pool of storage
- AppsON integrated VMware ESXi hypervisor
- In-line always-on data reduction with a 4:1 guarantee with no assessment required
- Support for persistent Storage Class Memory drives
- Intelligent data placement with Machine Learning load balancing
- Anytime controller upgrades
NetApp AFF advantages
- Software runs on multiple generations of hardware
- Tight integration with the leading public clouds (Amazon, Microsoft and Google)
- Scale-out NAS with support for multi-PB file systems
- Software-defined option
- NVMe over FC and 100GbE
- Double drive failure protection
- Clusters with All-flash and Hybrid arrays
- NAS, synchronous and active/active replication, and replication to Hybrid arrays
- Advanced integrated snapshot based data protection, QoS and VMware NFS integration
As always it’s not as simple as one product being better than the other, it comes down to your specific requirements and priorities. So if you are considering purchasing a new all-flash storage array, or maybe a hybrid one, then do get in contact as we can use our many years of experience to help you compare and contrast the two vendors offerings.
