Impact of CPU hyper-threading

7

Enabling CPU hyper-threading allows the system to identify more number of CPU cores than the actual physical CPU cores.

Configuring CPU Hyper-Threading
Hyper-Threading improves parallelization of computations (doing multiple tasks at once) performed on x86 microprocessors. Although a single-thread chip can process thousands of instructions per second, only one instruction can be performed at a time. Hyper-Threading allows multi-thread processing at the same time, improving chip performance. You can enable or disable Hyper-threading on the BIOS: ? Romley platform BIOS: Advanced->advanced processor->Intel HT Technology ? Grantley platform BIOS: Advanced -> Intel RC Group -> Processor Configuration -> Hyper-Threading [ALL] ? Brickland platform BIOS: IntelRCSetup�?Processor Configuration�?Hyper-Threading [ALL]

Introduction to the Dorado Hyper features
Dorado series storage systems provide multiple data protection features, improving the data security of the storage systems and offering a solid foundation for data backup and disaster recovery. -The snapshot feature provides a mapping table for locating data so that data copies can be rapidly accessed. -Remote replication creates an available data duplicate of a local storage system almost in real time on a storage system that resides in a different region. The duplicate is instantly available without data restoration operations, protecting service continuity and data availability to the maximum extent. Remote replication is the core of the disaster recovery technology. -LUN copy is a data copy technology that quickly transfers data within a device or between devices. Clone, a type of snapshot technology, obtains fully populated point-in-time copies of source data. Clone is a backup approach that allows incremental synchronization. -HyperMetro enables that both data centers are active and bear services together to improve overall serviceability and resource utilization. -HyperMirror is a continuous data protection technology. It creates two physical mirror copies for a LUN to achieve continuous LUN backup and protection.

For S series switches, what is the impact of excessive ARP Replies on the CPU
For S series switches: If excessive ARP Reply packets are sent to the CPU, the CPU may be overloaded. Run the display cpu-defend configuration packet-type arp-reply all or the display cpu-defend statistics packet-type arp-reply all command to check whether excessive ARP Reply packets are sent to the CPU. In the display cpu-defend statistics packet-type arp-reply all command output. if the value of the Drop (Bytes) field is large, excessive ARP Reply packets are sent to the CPU. In this case, adjust the CPCAR value for the ARP Reply packet. When an attack occurs, determine the attack source. You can use the packet obtaining function or enable debugging to check the attack source and configure the blacklist to reject the attack source. Note: Improper CPCAR settings may affect services on your network. It is recommended that you contact Huawei engineers before adjusting the CPCAR settings.
