About this release
Release 4.0.1 of the HCSF appliance consists of version 4.0.1.8 of the HCSF Hardware Setup Tool (HWST), version 4.0.1.110 of the HCSF operating system, version 4.0.1.36 of the HCSF software and version 4.0.1.3 of the HCSF tools.
What's new in this release
With the HCSF Appliance 4.0.1 release, there are two new hardware server platforms being introduced, the Entry, and the General Purpose.
� Entry platform based on Supermicro hardware.� The Entry system comes with eight servers in a single 4U chassis, each with their own CPU, memory, and six NVMe drives for data storage.� The system can be used as a complete HCSF solution with the addition of switches and data cables to connect the servers to the customer network(s).
� General Purpose platform based on Supermicro hardware.� The General Purpose system consists of a minimum of six 2U servers, each with their own CPU, memory, and between ten and twenty NVMe drives for data storage.� The General Purpose system has two options for CPU (32 core or 64 core).� The system requires switches and data cables to connect the servers to the customer network(s).
With the HCSF Appliance 4.0.1 release, there is the introduction of a Hardware Setup Tool.
� The HCSF Hardware Setup Tool (HWST) is used to ensure firmware on the hardware components are at the proper versions and the correct configuration has been applied to the firmware.� The HWST should be run on every server to initially set the hardware components to a known state and will be used in the future to update versions of firmware on various hardware components in the HCSF solution.
With the HCSF Appliance 4.0.1 release, there is the introduction of a custom RedHat Enterprise Linux 8.6 operating system.
� Hitachi Vantara will be standardizing on the RedHat Enterprise Linux operating system for the HCSF platform.� A customized version of the RedHat Enterprise Linux operating system will be installed as part of the HCSF solution and will be updated as part of the HCSF solution.
With the HCSF Appliance 4.0.1 release, there is a new version of HCSF software being introduced - version 4.0.1.36.
� Customers who purchase an HCSF Appliance system (under the SSA agreement with Supermicro) will be installing the 4.0.1.36 version of software and the hardware, OS, and software are all supported by Hitachi Vantara, LLC.
� Customers who previously purchased and HCSF product (under the MTSA agreement with Supermicro) may not use the HCSF Appliance components to upgrade their existing systems.� Support for these systems will continue to come from the vendors.� Hardware support will continue to come from Supermicro, software support will continue to come from Weka IO, and OS support will come from the vendor chosen by the customer.
Important notice
Please take note of all safety and important call-outs in the system installation documentation.
Document set
The following documents contain information about the HCSF appliance:
� HCSF Appliance Onsite Setup Guide, FE-HCSF001
The HCSF Appliance Onsite Setup Guide describes the physical requirements, physical installation, and software installation instructions for both the Entry and General Purpose HCSF appliances.� After completing a proper design for the customer use cases, the Onsite Setup Guide will guide the Hitachi Vantara CS&S and GSS organizations through the assembly and configuration of an HCSF system.
� HCSF Appliance Maintenance Guide, FE-HCSF002
The HCSF Appliance Maintenance Guide describes the physical server maintenance procedures for the HCSF solution.� Most of the material in the Maintenance Guide is extracted from Supermicro documentation for this release to minimize time to market.� Many of the procedures will be improved over time and a few missing procedures will be added.� Specifically, there are missing maintenance procedures for replacement of the server motherboard, drive backplane, and chassis for both the Entry and General Purpose platforms.
� HCSF Appliance Engineering Change Notice, ECN-HCSF009-00
The HCSF Appliance Engineering Change Notice describes in detail the exact hardware components, part numbers, firmware versions, system limits, access points, supported browsers, field replaceable units, and more.� The HCSF ECN should be used as the reference for specific system information related to the HCSF solutions.
