The QLogic 2770 Series 32 Gb Fibre Channel (FC) Host Bus Adapters (HBAs) are Generation 6 (Gen 6) FC adapters for Lenovo ThinkSystem servers. These adapters offer industry leading native FC performance with extremely low CPU usage with full hardware offloads. With performance of up to 1 million I/O operations per second (IOPS) per port, these adapters can be used to support all-flash arrays (AFAs) -- Fibre Channel storage systems comprised completely of high-speed solid-state drives. This product guide describes the QLogic 2770 Series HBAs for Lenovo servers and provides essential pre-sales information to understand the products, their key features and specifications, and compatibility. This guide is intended for technical specialists, sales specialists, sales engineers, and IT architects who want to learn more about the adapters and consider their use in IT solutions.

Second-generation Xeon Scalable processors are limited to the amount of memory they can address, as follows:- Processors with an L suffix (eg 8260L): Up to 4.5 TB per processor- Processors with an M suffix (eg 8260M): Up to 2 TB per processor- All other processors: Up to 1 TB per processorThe calculation of the total memory per processor includes both the system memory DIMMs and the Persistent Memory DCPMMs installed in the server.For example:- A configuration using 12x 64GB DIMMs per processor is a total of 768 GB, which means that neither an M nor an L processor is required- A configuration using 12x 128GB DIMMs per processor is a total of 1.5 TB, which means that an M processor is required- A configuration using 6x 32GB DIMMs + 6x 256GB DCPMMs is a total of 1.69 TB which means an M processor is required (an L processor may also be used)- A configuration using 6x 128GB DIMMs + 6x 512GB DCPMMs is a total of 3.75 TB which means an L processor is requiredThe following table lists the features of the supported second-generation Intel Xeon processors.
