The Dell EMC PowerMax product family consists of two models: the PowerMax 2000 array and the PowerMax 8000 array. The PowerMax 2000 array provides customers with efficiency and maximum flexibility in a 20U stack height, while the PowerMax 8000 array is designed for massive scale, performance, and IOPS density within a two-floor-tile footprint. Both PowerMax models are based on the Dell EMC Dynamic Virtual Matrix architecture and a version of HYPERMAX OS that was rewritten for the NVMe platform. This HYPERMAX OS version is called PowerMaxOS.
Like the VMAX All Flash arrays, PowerMax arrays are specifically designed to meet the storage capacity and performance requirements of an all-flash enterprise data center. PowerMax products take advantage of the higher-capacity NVMe flash drives that are used in the densest configuration possible. PowerMax technology offers enterprise customers trusted data services along with the simplicity, capacity, and performance that their highly virtualized environments demand, while still meeting the economic needs of traditional storage workloads. Furthermore, the PowerMax platform enables you to deploy applications such as real-time analytics, machine learning, and big data, which require lower storage latency and higher IOPS densities than what was attainable with previous all-flash offerings.
The following figure shows the essential features of the PowerMax 2000 and 8000 arrays.

PowerMax configurations consist of modular building blocks called Bricks. The modular Brick architecture reduces complexity and enables easier system configuration and deployment. This architecture also enables the system to scale while continuing to deliver predictable high performance.
Two types of Brick blocks are available for PowerMax configurations:
The initial Brick block includes a single engine consisting of two directors, two system power supplies (SPS), and two 24-slot 2.5 in. NVMe Drive Array Enclosures (DAE24) preconfigured with an initial total usable capacity. The Brick 2000 block comes with an initial capacity of 11 or 13 TBu, depending on the RAID configuration. The PowerMax 8000 array model comes with an initial capacity of 53 TBu for open systems, 13 TBu for mainframe, and 66 TBu for mixed systems. Each Brick block comes preloaded with PowerMaxOS software.
The Brick concept makes it possible for the PowerMax platform to scale up and out. Customers can scale up by adding flash capacity packs, which include NVMe flash drive capacity that can be added to a PowerMax array. Each flash capacity pack for the PowerMax 8000 system has 13 TBu of usable storage. For the PowerMax 2000 model, each pack has 11 TBu or 13 TBu, depending on the RAID protection type selected. Scale out a PowerMax system by aggregating up to two Brick blocks for the PowerMax 2000 array and up to eight blocks for the PowerMax 8000 array in a single system with fully shared connectivity, processing, and capacity resources. Scaling out a PowerMax system by adding additional Brick blocks produces a predictable, linear performance improvement regardless of the workload.
The PowerMax provides multiple front-end connections that implement several protocols and speeds. The following table shows the various front-end connectivity modules that are available for a PowerMax system.

All PowerMax arrays come preloaded with PowerMaxOS software. Software for the PowerMax system is available in different packages, each with additional optional features. For up-to-date information about these options, see the Dell EMC PowerMax Family Overview White Paper.
PowerMax arrays provide a full NVMe flash storage backend for storing customer data.
The PowerMax NVMe architecture provides:
PowerMax uses a new active/active RAID group accessing scheme called smart RAID. Smart RAID allows the sharing of RAID groups across directors, giving each director active access to all drives on the Brick or zBrick block. Both directors on an engine can drive I/O to all the flash drives, creating balanced configurations in the system whatever the number of RAID groups and providing performance benefits.
Smart RAID also offers increased flexibility and efficiency. Customers can order PowerMax systems with a single RAID group, allowing for at least nine drives per engine with RAID 5 (7+1) or RAID 6 (6+2 and 1 spare) and as few as five drives per system for a PowerMax 2000 with RAID 5 (3+1 and 1 spare). These configurations leave more drive slots available for capacity upgrades in the future. When the system is scaled up, customers have more flexibility because flash capacity pack increments can be a single RAID group.
The Symmetrix Remote Data Facility (SRDF) is considered a gold standard for remote replication in the enterprise data center. Up to 70 percent of Fortune 500 companies use SRDF to replicate their critical data to geographically dispersed data centers throughout the world. SRDF offers customers the ability to replicate tens of thousands of volumes, with each volume being replicated to a maximum of four different locations globally.
SRDF is available in three types:
Every PowerMax array includes the local replication data service TimeFinder SnapVX, which creates low-impact snapshots. Local replication with SnapVX starts by creating a snapshot, a pointer-based structure that preserves a point-in-time (PIT) view of a source volume. Snapshots do not require target volumes. Instead, they share back-end allocations with the source volume and other snapshots of the source volume, and only consume additional space when the source volume is changed. A single source volume can have up to 256 snapshots.
You can access a PIT snapshot from a host by linking it to a host-accessible volume called a target. Target volumes are standard thin volumes. Up to 1,024 target volumes can be linked to the snapshots of a single source volume. By default, targets are linked in a no-copy mode. This functionality significantly reduces the number of writes to the back-end flash drives. It eliminates the need to perform a full-volume copy of the source volume during the unlink operation to continue using the target volume for host I/O.
PowerMax arrays use the Adaptive Compression Engine (ACE) for inline hardware compression. The ACE data-reduction method provides a negligible performance impact with the highest space-saving capability. PowerMax technology uses inline hardware-based data deduplication. This method identifies repeated data patterns on the array and stores those that are repeated once only, thus preventing the consumption of critical PowerMax system core resources and limiting performance impact.
The embedded NAS (eNAS) data service extends the value of PowerMax to file storage. eNas enables customers to use vital enterprise features such as flash-level performance for both block and file storage, as well as to simplify management and reduce deployment costs.
eNAS uses the hypervisor in PowerMaxOS to create and run a set of virtual machines (VMs) within the PowerMax array. These VMs host two major elements of eNAS software: data movers and control stations. The embedded data movers and control stations have access to shared system resource pools so that they can evenly consume PowerMax resources for both performance and capacity.
With the eNAS data service, PowerMax becomes a unified block-and-file platform that uses a multicontroller, transactional NAS solution.
