Infinite scale. Infinite possibilities.

ExaFlash all-flash arrays offer virtually infinite on-demand scalability, up to 95% lower energy consumption, unmatched multiprotocol support, and up to 50x greater rack density, all at less than half the cost of competing solutions. ExaFlash was engineered to enable the adoption of flash at scale, simplifying management and maximizing the efficiency of flash to the fullest.

Existing Approaches Fall Short

Conventional scale-up and scale-out architectures were never designed with flash in mind. Both approaches are legacies of the hard drive era, when processors were fast and storage was slow. In scale-up designs, flash is cascaded behind a fixed set of controllers, reducing effective performance as capacity is added. Scale-out was designed to overcome this by combining a controller and flash in one node and then striping data across nodes for capacity and redundancy. However, this approach is grossly inefficient, resulting in poor utilization of flash capacity, unpredictable latency at scale, very high power consumption, and excessive rack space requirements.

ExaFlash is Built for Flash at Scale

With ExaFlash, data flow is decoupled from metadata, and management is centralized, operating completely out-of-band. This approach ensures that customers have one interface and one pane-of-glass for all administration. There is no data network between the storage arrays themselves, guaranteeing that performance truly scales in lock-step with capacity and with consistent latency.

ExaFlash Operating System

The ExaFlash Operating System is powerful, API-driven storage and data management software for the ExaFlash platform.

Superior Versatility for Greater Consolidation

The ExaFlash OS provides a single pane-of-glass administration interface for total control. The ExaFlash Operating System also provides support for all major storage protocols, including block, file and object protocols, simultaneously. Using the API, storage administrators can automate every conceivable storage task centrally.

Comprehensive Data Management Features

The ExaFlash OS incorporates flash-optimized parity protection and hot-spares to protect individual flash drives against failure. Unlike conventional RAID approaches that can suffer from long rebuild times and silent data corruption, the ExaFlash OS incorporate real-time full data checksums that proactively monitors and repairs any mismatches. Space-efficiency point-in-time snapshots as well as full data clones are supported. Inline variable deduplication and LZ4 compression maximize storage utilization.

Precision-engineered All-Flash Arrays

ExaFlash Arrays feature our patented Parallel Memory Architecture, active-active controllers, and embedded hardware-acceleration to deliver exceptional performance. ExaFlash Arrays are available in four sizes (A-series, B-series, C-series, and D-series), ranging from 12 TB to 4.5 PB raw (up to 13.5 PB effective capacity). Since each ExaFlash Array is highly-available, there is no minimum number of arrays necessary – start with one and expand on-demand. Multiple storage protocols, including block, file, and object, can operate simultaneously using Ethernet, Fibre Channel, and InfiniBand networks, eliminating storage “islands”.

Unparalleled Data Center Efficiency

Unlike off-the-shelf servers, ExaFlash Arrays are precision-engineered for maximum efficiency and performance. ExaFlash Arrays draw 95% less power per terabyte than competing designs by eliminating irrelevant components and minimizing CPU utilization through intelligent hardware-offload engines. ExaFlash Arrays also incorporate ultra-dense MLC flash drives to deliver up to 50x the capacity in the same rack space as competing alternatives.
