These requirements and recommendations are considered for shared storage clusters: 1. For a non-shared disk with at least one HbA card, such as a system (BOOT) disk, it is recommended to use two HbA cards to connect to an internal disk and mirror the system disk to eliminate single node faults. 2. For a shared disk, there must be at least one HbA card: -To elimi

After the storage arrives, the process is usually shelving, wiring, and power-on. After confirming that the configuration is correct, create an array and lun as required. After several hours, the system will be able to handle the problem. Then, the storage is connected to the San according to the actual needs. Select a zone on the switch so that the host's HbA can see the corresponding controller. Finally, the storage partition to be discussed is left

calculated in milliseconds (1‰ seconds. the average rotation delay is half the time the disk is rotated in the entire circle. same as seek time, the size of the rotation delay moving in the random fan interval in read/write operations is more important than the speed indicator of the adjacent slice. the average rotation delay of 5400 to 5.5 disks per second is about 15000 milliseconds. For to 2 milliseconds. Data Transfer Rate The data transmission rate (also called the data transfer rate)

PMC launches industry's first 12gb/s SAS expansion card for high-density data center serversThe Adaptec PCIe expansion card provides 24 ports for next-generation servers,Connect more high-performance HDDs and SSDs A PMC that leads Big data connectivity, delivery, and storage, delivering innovative semiconductors and software solutions ? The Company (NASDAQ:PMCS) recently launched the industry's first 12gb/s SAS expansion card to enable high-density servers. IDC [i] believes that high-density ser

After the store arrives, usually the flow is on the shelves, on the line, and then on the electricity. After confirming that the configuration is correct, start creating the array and Lun as required, and after a few hours the system is basically done. The storage is then connected to the SAN based on actual needs. There is a need to zone on the switch so that the host's HBAs can see the appropriate controller. Finally, with the remaining storage Partition to be discussed, map the predefined LUN

total of 28 hard drives. Piece of hard disk 300G,The total is 300g*28=8400g about 8.2TThis overall is a 8 t storage. 8000G is enough for the general data.This storage is counted as a small to medium storage. Small storage puts fewer hard drives. In order to cooperate with Oralce's study, it is necessary for us to describe the approximate knowledge of storage. After the storage, you can see the controller, power,Storage is generally dual-control dual-power, the storage itself is redundant. The c

Therefore, the hull of the model should be accurate in line, firm structure, smooth surface, and strong water tightness.It is simple and the hull of the initial model, with simple structure and easy processing. The simplified solid ship model can be made of solid wood. The paper model is made by folding, cutting, and sticking. The bottom of the ship and the ship side of the preliminary model are relatively straight and can be made of thin boards and wood slices. (Figure L01)Medium an

Then we open the Appearance Control Panel (SHIFT+F6) and create a new fill color, make sure the new fill is at the top, and then fill it with a linear gradient of gray, white 6 knots, and a total of 8 control points. Let's add the fill setting to the blending mode to darken. Next, we'll continue to create a new layer of dark gray fill color, make sure the fill color is on top, then add new effects

seen on server B. After troubleshooting, the new server's HbA card is somewhat incompatible with the SAN Switch, you need to plug it in. The HbA card of the new server is 2/4/8 GB adaptive, and the optical fiber card of the SAN Switch is 2/4 GB adaptive. Therefore, inconsistency may occur. But it doesn't matter. Just re-plug the HBA card or change the speed of t

connection pool to maintain the web site. Therefore, as more connections are blocked, the Web site creates more connections, and these connections are blocked, this cycle will continue. The log write operation will be completed in about 45 seconds, but hundreds of connections have accumulated so far, leading to blocking problems, it takes several minutes for SQL Server and applications to be restored. When combined with Application Problems, latency I/O conditions will have a very negative impa

When a PC server host connects to FC storage, it is generally necessary to install an HBA card, and an important parameter of the interface is the WWN number. The way to view the WWN number under Redhat or SuSE is as follows. One, SuSE Linux 9 View the/proc/scsi/qla2xxx/* and filter the WWN information for the FC HBA card with the Adapter-port keyword: # cat/proc/scsi/qla2xxx/* | grep adapter-port scsi-qla

Some knowledge about storageAccording to the different transmission protocols, the network card can be divided into three kinds, one is the Ethernet card, the second is the FC network card, the third is the iSCSI network card. Ethernet Card: The Scientific name Ethernet Adapter, the transmission protocol for the IP protocol, generally via fiber optic cable or twisted pair with Ethernet switch connection. The interface types are divided into optical and electrical ports. Optical ports ar
