nvme over fabrics

What the hell is an RDMA? It is believed that most children who do not care about high-performance networks do not know much. But the advent of nvme over fabrics let the storage have to take time to look at this thing, this article will introduce the RDMA I know.RDMA (Remote Direct memory access) is intended to directly access the host's memory at the remote, without the need for host involvement . For exam

NGFF (Next Generation Form Factor), as the name suggests, is the standard of Form Factor. It is tied with NGFF for 2.5 "instead of PCIe. (In addition, NGFF has now been renamed M.2. We 'd better keep pace with the times and change it to M.2 .)PCIe is a bus standard, tied with SATA.NVMe is a new transmission standard for hard disks and replaces the current AHCI.Why do people always associate NGFF/M.2 with PCIe/NVMe? This is because the SSD in

In July June, shengze fabric market sales entered the off-season, and the overall market sales showed a significant decline. Due to the decrease in sales volume, some operating companies also began to adopt a sales price reduction strategy in order to recover funds. Therefore, the expected prices also fell this month, this is a good example of the trend in the "Fiber Fabric Purchasing Index" (SEE) in the China shengze silk fiber Index released by the Ministry of Commerce in June. Figure shows th

NVMe SSDs are the evolution direction of storage disks, and NVMe SSDs have more than ten times the performance growth compared to SATA/SASSSD. This is mainly due to the NVMe SSD Multi-queue technology, through the multi-queue technology can be IO access parallelization, so as to improve the overall performance of the system. in theNVMein the storage ecosystem,Ss

as flash capacity continues to rise, prices continue to fall, and applications are increasing, pushing flash storage systems to replace traditional disk systems. Compared to traditional disk systems, storage-system design considerations are subject to significant changes due to changes in storage media. This change is directly reflected in the change of storage system software architecture, that is, the so-called storage software stack reconfiguration. For Sata/sas SSDs , the performance of the

Although Windows 7 is supported by the XPS 9350 series, it is not easy to install. If you follow the normal process of writing Windows 7 MDSN ISO to a USB flash drive, and then booting the installation, first of all, because of the lack of NVME driver can not find the hard disk, and after solving this problem, the lack of USB 3.0

While the installed rate of Windows 10 systems is rising, the classic Windows 7 still has a large user base. Especially in China, Windows 7 is still the preferred system for many computer users.Enduring Windows 7However, since the era of the Skylake architecture processor, users have found a lot of problems in installing Windows 7 on a new computer. In fact, this is mainly caused by the lack of some necessary drivers for native Windows 7:Previous generation Skylake platform to install Windows 7,
