HPE Fast Fault Tolerance vs HPE Advanced ECC Support – Choosing Best Technology!
Memory failure is one of reasons that can be cause of server crash and impact on service availability and performance. Think about a service which including multiple servers, server could be crashed cause of single memory module failure or uncorrectable memory error. Regarding to preventing memory impact of memory errors on services, HPE provides RAS technologies. RAS (reliability, availability, and serviceability) technologies are including: In this post, we’ll compare HPE Fast Fault Tolerance and HPE Advanced ECC Support. Before comparison, let’s find that why we need to memory RAS? Why Memory RAS is needed? Server uptime is still one of the most critical aspects of data center maintenance. Unfortunately, servers can run into trouble from time to time due to software issues, power outages, or memory errors. The three major categories of memory errors we track and manage include correctable errors, uncorrectable errors, and recoverable errors. The determination of which errors are correctable and uncorrectable is completely dependent on the capability of the memory controller. Correctable Errors Correctable errors are, by definition, errors that can be detected and corrected by the chipset. Correctable errors are generally single-bit errors. All HPE servers are capable of detecting and correcting single-bit errors and...
