Product Features
Technical Overview
At the heart of the SR655 is the AMD EPYC 7702P, a 2nd generation processor with 64 cores running at 2.0 GHz base frequency and 256 MB of L3 cache. The platform uses an AMD chipset and supports single-socket operation, balancing performance with power efficiency.
Memory architecture leverages TruDDR4 technology at 3.20 GHz with ECC and registered buffering for data integrity. The 16 memory slots allow expansion to 2 TB, accommodating large datasets and virtualization hosts. Storage is managed by a Serial ATA controller, with hot-swappable drive bays for maintenance flexibility.
