Dell EMC today announced PowerMax. Described as the next generation of VMAX, it’s been designed from the ground up to support NVMe. It’s being pitched as suitable for both traditional applications, such as:
- Virtual Machines;
- Relational Databases; and
And “next generation applications”, such as:
- Real time analytics;
- IoT; and
- Mobile Applications.
From a performance perspective, Dell EMC tell me this thing can do 10M IOPS. It’s also been benchmarked delivering 25% better response time using NVMe Flash (compared to a VMAX AF using SAS Flash) and 50% better response time using NVMe SCM (Storage Class Memory). They also say that can get 150GB/s out of a single system.
- End to End NVMe
- NVMe over Fabric Ready (soon)
- NVMe based drives (dual ported) – Flash and SCM (*soon)
- NVMe-based Disk Array Enclosure
- Industry standard technology

Scalability and Density
Starts small, and scales up and out.
- Capacity starts at 13TB (effective)
- As small as 10U
- Scales from 1 Brick
- Scales to 8 Bricks
- 4PB (effective) per system

From a storage efficiency perspective, a number of features you’d hope for are there:
- Inline dedupe and compression – 5:1 data reduction across the PowerMax
- No performance impact
- Works with all data services enabled
- Can be turned on or off by application
There are two different models: the PowerMax 2000 and PowerMax 8000.
- 1.7M IOPS (RRH-8K)
- 1PB effective Capacity
- 1 to 2 PowerBricks
- 10M IOPS (RRH-8K)
- 4PB effective Capacity
- 1 to 8 PowerBricks
PowerMax Software comes in two editions:
- Non-disruptive Migration
- iCDM Basic
The Pro edition gives you all of the above and
- iCDM Advanced
The PowerMax is available from May 7, 2018.
Dell EMC tell me the VMAX 250 and 950 series aren’t going away any time soon, but there will be tools made available to migrate from those platforms if you decide to put some PowerMax on the floor. PowerMax is an interesting platform with a lot of potential, hype around the quoted performance numbers notwithstanding. It seems like it takes a lot of floor tiles compared to some other NVMe-based alternatives, although this may be down to the scale of the platform. It stands to reason that the kind of folks interested in this offering are the same ones that were interested in VMAX All Flash. I’d be curious to see what the compatibility matrices look like for the existing VMAX tools when compared to the PowerMax, although I do imagine that they’d be a bit more careful about this then they have been with the midrange products.
