It is a good way of thinking to study some games and find people's value orientation. This is in line with the experiment "experiment, thinking, and expression" mentioned in "true and false learning. In my blog, what I like most is to share the fun of reading their articles. Today, we recommend Wang jianshuo's article "the reason for being a good person. As for good people, in the real world, their reputation has never been very bad. The reason is that "good people" is like "stupid". If good peo

Description
There are many pretty girls in Wuhan University, and as we know, every girl loves pretty-clothes, so do they. One day some of the them got a huge rectangular cloth and they want to cut it into small rectangular pieces to make scarves. But different girls like different style, and they all style A, price voted down on a list. They have a machine which can cut one cloth into the exactly two small
Filters have always been, with the replacement filter for the MM flower clothing, has become a more widely recognized method of PS. The aim is to hope that the pattern pattern on the cloth is distorted and deformed with the folds. This desire is good, is a further to make a better effect of the pursuit.
But I do not know, how do you do the replacement map. If you follow the "Select All/GO/Save As replacement" method in the tutorial, I would like to s
All along, with the replacement filter for the MM flower clothing, has become a more recognized PS industry method. The aim is to hope that the pattern pattern on the cloth is distorted and deformed with the folds. This desire is good, is a further to make a better effect of the pursuit.
But I do not know, how do you do the replacement map. If you follow the "Select All/GO/Save As replacement" method in the tutorial, I would like to say: there is a pr
advantages in terms of density, performance and reliability. Lenovo 8885E by the PMC card provides customers with a scalable, scale-out storage solution that can be expanded on demand. ”The Lenovo 8885E by PMC Card is a half-height, an HBA card that provides 8 sas/sata ports for external connections to 6gb/s and 12gb/s JBOD. The card is seamlessly and reliably connected to Lenovo's Jbod via the PMC 12gb/s SAS Extender. The card supports all common op
What are the hardware requirements for deploying FCoE? What are your suggestions for optimizing FCoE deployment?
In general, FCoE needs a switch that can bridge the data center to datacenterbridging, DCB) to expand the traditional Ethernet so that it is suitable for transmitting storage traffic without losing data. Some, but not all) Ethernet vendors support the dcb feature of the 10GbE switch. At the same time, the converged network adapter convergednetworkadapter, CNA) is suitable for FCoE. CN
. Then, the second host sends an I/O request before it needs to resend the SCSI reservation command to the disk.Classification of SCSI Locks:There are two types of SCSI locks: SCSI-2 Reservation and SCSI-3 reservation. Only one type of SCSI lock can exist on a LUN.SCSI-2 reservation only allows the device to be accessed by a SCSI lock initiator, which is the host's HBA. For example, HBA1 on Host 1 adds a SCSI-2 lock to the LUN that is accessed, even i
After a long period of monitoring, found Iostat in the%util high, has been in 98% up and down, indicating that the bandwidth occupancy rate is highly, encountered a bottleneck.and read and write speed is very slow, after troubleshooting, found that the HBA card problems, after replacement, with the DD if command test, the disk read and write speed has been more than 10 times times the promotion.But after replacing the

Remote differential compression: When the bandwidth is tight, you can bind multiple NICs to one to increase the maximum bandwidth. If there is only one, data differential compression is very economical.
Multi-path IO: if there are two or more HbA cards on the server, in order to increase the throughput bandwidth with storage and prevent the storage network from spof, You need to configure it (the current test environment does not even have o
following examples show where RDM is needed rather than a Virtual Disk: in the MSC cluster, RDM is required to provide quorum and data disks. This includes V2V clusters and p2v clusters across ESX hosts. Note that the virtual disk can be used as the "cluster-in-a-box" configuration on a single physical host. RDM is required in the solution of the application that San knows in the virtual machine. There are many examples of this situation, such as the snapmanager series applications of netapp. T

In the above case, if you use VB statements or functions to implement it, you need to write a very short code, and because you need to use the sequential search method to complete it, therefore, code execution efficiency is also low. If the sendmessage function is used, the amount of code can be greatly reduced and the execution efficiency can be greatly improved.
Using the sendmessage function to complete the preceding two tasks is very simple. Each task simply sends a message to multiple ro

I talked to my friends about how to improve the performance of SQL Server and found some problems. For SQL Server, in addition to following the best practices of OS and applications, what are the optimization methods?
Hardware-level optimization is also very important, especially storage optimization. After talking about this, we started to explain the SAN issue from the DBA's perspective.
Many factors affect the disk I/O performance, such as shared or dedicated disks, RAID level, bus speed, and
