Disk back panel: Eclectic In the tower server where the rack server or the hard drive slot is higher, the SAS Hba/raid card is generally not connected to the hard drive directly with the SAS cable, but through the disk backplane to facilitate the hard drive Plug and unplug. Disk Backplane is also a typical internal connection application, one side of the hard drive, the other side even Hba/raid card. Drive

, because in each case you could immediately imagine or construct a theoretical test method to prove it.2. FAT Tree Network and network level ClosTo say the fat tree concept, you can start with the architecture of the infiniband[Note 1] switch. The InfiniBand switch is prone to 288 ports (port rate 10g/20g/40g), and its chip is a fat tree to build a high-density port switch. Note The 1:

, there is still not much attention in general. What is the prospect of Storage Network virtualization? Is it the Great Northern land that has never been reclamation )? Storage Network Overview A storage Network, also known as the storage Domain Network StorageArea Network (SAN), is a dedicated Network that provides unified access to block-level data storage. The supporting technology is fiber channel (FC. FC is not the only choice for building a storage network, but a dominant technology in the

this value must be specified. Mclt statement Mclt seconds; The mclt statement defines the maximum client boot time (maximum client lead time). It must be specified on the master server and not on the secondary server. This is the lease update duration assigned by the partner server without communication. The longer the setting, the longer the running server will be able to resume to the partner-down; the shorter the setting, the larger the load when the server cannot communicate. It may be bett

The Hyper-V virtual Fibre Channel feature for virtual machines enables virtual machines to access Fibre Channel-based storage devices. This feature enables enterprises to virtualize workloads that require Fibre Channel usage, and enables enterprises to create clusters using Fibre Channel with guest operating systems running in virtual machines.The Virtual Fibre Channel adapter provides port virtualization capabilities by providing a host bus adapter (HBA
