High Availability | High Availability
Availability should factor in the initial planning and budgeting stage. It is often necessary to buy redundant subsystems and components to mitigate risk and minimize downtime, even if it will run up expenses. Single points of failure (SPOF) must be eliminated. You also need to prepare a business continuity plan (BCP) for major outages; the BCP should cover how operations can continue during an outage, how normal operations can resume as soon as possible (sometimes called a disaster recovery plan, DRP), and how business will be affected as a result of the outage (sometimes called a business impact analysis, BIA).
a. Smart Crises Management and Protection (SCMP): SCMP is a GIGABYTE-patented feature that is deployed in servers with non-fully redundant PSU designs. With SCMP, in the event of a faulty PSU or the system overheating, the system will force the CPU to go into ultra-low power mode, which reduces the power load and prevents the system from unexpected shutdowns.
b. Smart Ride Through (SmaRT): To prevent server downtime and data loss as a result of power loss, GIGABYTE has implemented SmaRT in all the server platforms. When a power loss event occurs, the system will throttle while maintaining availability and reducing power load. Capacitors within the power supply can provide power for ten to twenty milliseconds, which is enough time to transition to a backup power source for continued operation.
c. Dual ROM Architecture: In case the ROM that stores the BMC and BIOS fails to boot, the system will reboot with the backup BMC and/or BIOS. Once the primary BMC is updated, the ROM of the backup BMC will automatically update the backup through synchronization. For the BIOS, it can be updated based on user's choice of firmware version.
