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

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

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

Redundancy of storage spaceIn the high-availability architecture of the storage controller server, there is a difference in the degree of redundancy that is achieved by using a different number of JBOD or different ways of storage space layout. If you cannot turn on storage box-level redundancy by using two storage bins, so you cannot implement JBOD storage-tier redundancies, you must use three

heatsink to ensure that the processor is adequately cooled. 5 PCI expansion slots are available on the motherboard, including 4 pci-x slots and a 32bit 33MHz PCI slot. The two pci-x on the left side of the picture above are controlled by 1 Pci-x Bridge, the right two pci-x have another 1 Pci-x bridge control, the rightmost slot can support the ZCR expansion card.

Storage space Storage space is a new feature in Windows Server 2012 that provides an efficient and convenient storage virtualization solution. In simple terms, it can put a standard storage device into a storage pool and virtualize it to create a virtual disk called storage space. Currently compliant storage devices include disk or

. The core Hyper-V Server for Windows Server virtualization has high requirements for storage networking, and here are a number of options: While Hyper-V virtual machines can be deployed in Das, Nas, or SAN storage, for high availability, SAN-based is the most common (iSCSI-based IP San and FC-channel-based FC San), and you can now choose a file server cluster-based Hyper-V over SMB (a small network that can be used in conjunction with the "Storage space" feature to be mentioned later in this ar

These applications include transactional processing and Office applications that have many users accessing small files. JBOD:JBODis a class of important storage devices in the storage domain. JBOD(Just a Bunch of Disks, a disk cluster) is a storage device with multiple disk drives
