Servers Built for the Cloud

Predictable Performance

What sets our range of Ampere Altra based servers apart from our AMD or Intel based solutions is the elimination of the traditional "noisy neighbour challenge".

Ampere Altra processors are available with up to 80 single threaded cores running at up to 3.3GHz speed. Each of these cores gets a dedicated 64KB of L1 l-cache, 64KB L1 D-cache and a huge 1MB of L2 cache to ensure consistant and predictable performance.

Coherent mesh-based interconnect topology provides efficient bandwidth with 32 distributed home nodes and directory-based snoop filters to enable seamless connectivity between the cores.

Supporting eight, 2DPC, 72-bit DDR4-3200 channels, the Ampere Altra processor offers high bandwidth and memory capacity of up to 4TB per socket.

High Scalability

With leading power/core, and multi-socket support, Ampere Altra provides the scalability to maximise the number of servers per rack, unparalleled in the industry.

With 128 lanes of PCIe Gen4 per socket with support for 192 PCIe Gen4 lanes in 2P configuration that can be bifurcated down to x2, Ampere Altra provides maximum flexibility to interface with off-chip devices, including networking cards up to 100 GbE or more, and storage/NVMe devices, making it well suited for big data applications.

Power Efficiency

Ampere Altra provides industry-leading power efficiency/core, while packing 80 cores in a single-socket

and 160 cores in a dual-socket platform, establishing new levels of power efficiency with scalability.

Ampere's power optimised design, coupled with 7 nm process technology, enables the Ampere Altra processor to pack in more cores than any other datacenter class processor – all on a single die – enabling datacenter infrastructure providers more cores per rack.

Ampere Altra processor's advanced power management capabilities include Advanced Configuration Power Interface (ACPI) v6.2 support, Dynamic Frequency Scaling (DFS), on-die thermal monitoring, and dynamic power estimation

Reliability, Availability, and Serviceability (RAS)

The Ampere Altra processor provides extensive enterprise server-class RAS capabilities. Data in memory is protected with advanced ECC in addition to standard DDR4 RAS features. End-to-end data poisoning ensures corrupted data is tagged and any attempt to use it is flagged as an error. The SLC is also ECC protected, and the processor supports background scrubbing of the SLC cache and DRAM to locate and correct single-bit errors before they accumulate into uncorrectable errors
