Avoid PCI IRQ affinity mapping when multiqueue is not supported (bsc#1123034 bsc ... /proc/irq/IRQ#/smp_affinity specifies which target CPUs are permitted for a given IRQ source. It's a bitmask of allowed CPUs. It's not allowed to turn off all CPUs, and if an IRQ controller does not support IRQ affinity then the value will not change from the default 0xffffffff. The catch here is that the bitmask is in hex.

An NVMe namespace is a storage volume organized into logical blocks that range from 0 to one less than the size of the namespace (LBA 0 through n-1) and is backed by some capacity of non-volatile memory. Mellanox Technologies (NASDAQ: MLNX) is a leading supplier of end-to-end Ethernet and InfiniBand intelligent interconnect solutions and services for servers, storage, and hyper-converged infrastructure. 直接来干货!怎么调优 PBlaze IV PCIe SSD NVMe。 Go! 1. 中断绑定 在Redhat 6.5中的NVMe驱动会自动把全部的中断向量绑定到core0上,如果有多个SSD, core0将会成为瓶颈。 (1) Turns off the IRQ balancer: [[email protected] ~]# service irqbalance stop (2) Ch IRQ Balancer Status ACTIVE Driver Status OK: MLNX_OFED_LINUX-4.0-1.0.1.0 (OFED-4.0-1.0.1) ConnectX-5 Device Status on PCI 84:00.0 FW version 16.18.1000 OK: PCI Width x16 >>> PCI capabilities might not be fully utilized with Broadwell CPU.

Insert the Ubuntu USB boot disk into the WHL Maxtang machine. Power on the machine, then press F11 to select the USB disk as the boot device. Differences in POST duration. The first noticeable difference is the boot up of the server – I didn’t do any precise timing measurements but it feels like the AMD-based server is approximately 50% slower during POST, to the extent that the Intel-based server does POST and the OS finishes boot before the AMD-based server finishes POST, so to me it’s an indication that the AMD platform is ...
