equal sign, that is, the left side of the equal sign is equivalent to the right side of the equal sign. In other words, we only changed the original expression A without losing any information. It's like 24 = 2*3*4. Therefore, if LSI directly uses SVD, not only R is uncontrollable, but R is likely to be too large to achieve dimensionality reduction, in fact, this operation not only does not reduce the dimension, but also consumes a lot of computing t

VMware, on the official blog today, said the use of PVSCSI storage adapter driver can improve 10-30% performance for high IO VMs. See Http://blogs.vmware.com/performance/2010/02/highperformance-pvsci-storage-adapter-can-reduce-cpio-by-1030.html We know that the default type of SCSI controller when creating VMS is the LSI Logic. Now under vsphere 4, you can select a new type PVSCSI (the option is VMware paravirtual), and this type can significantly

The company has several servers installed on esxi5.0 virtual machines. They used to use common desktops, now we have purchased a dedicated server and installed the LSI 8708 sas raid card (the server's onboard RAID card esxi is not supported). Now we need to migrate the virtual machine. The best method would have been to mount the array. Now the virtual machine is moved to the array and then to the new server. However, the company's array is full and t

1. If you have multiple raid on a LSI array card, you may report hard disk error (CentOS 6.6) If you need to install the system on the first raid, or you can create a raid on the system first. 2. Hot Plug the consequences: If the hard drive does not fail, RAID is normal, in the system running state to hot plug hard drive, will cause raid different steps, the entire RAID may appear various strange problems, For example: 1. HDD display off-line, red a

When a new technology or product emerges, everyone is eager to know whether or when the new product will completely replace the original product. In fact, many products have a "long tail effect". For example, when a disk backup occurs, people think that the tape will soon exit the market, but today the tape is still the main force of backup and archiving; after the emergence of SSD, many people think that it will eventually replace the mechanical hard disk, but at least from now on, it is not ea

With the development of LSI, the computer entered the fourth generation development. The fourth generation computer takes the large scale integrated circuit as the logic element and the memory, causes the computer to the miniaturization and the massive two direction development. From the first generation to the fourth generation, the architecture of the computer is the same, which is composed of controller, memory, arithmetic and input, called von Neu

the backup domain control register (rcc_bdcr. The lserdy in the backup domain control register (rcc_bdcr) indicates whether the LSE crystal oscillator is stable. In the startup phase, the LSE clock signal is released only after the bit is set to hardware 1. If allowed in the clock interrupt register, an interrupt request can be generated. The external clock source (LSE bypass) must provide an external clock source with a 32.768khz frequency in this mode. You can select this mode by setting the

ESG A global survey found that companies deploying server virtualization are also likely to have storage virtualization. Of the surveyed 332 deployed server virtualization respondents, 24% have implemented storage virtualization, and another 33% are planning to implement storage virtualization over the next year or two years. As can be seen, storage virtualization is the trend of the general. ESG Analysts also point out that combining virtualization with storage technology is really a good move.

Vmxnet 2 is an older generation of parallel virtual web, only applicable to esx/esxi3.5 and above the limited customer operating system, vmxnet 3 relatively new, but it seems only applicable to virtual machine version 7 virtual machine (virtual machine version set in the first two steps, The version recommended for use in ESXI5 is 8). These two cards provide better performance
