benchmark test, refer to http://www.tpc.org/tpcds/. 3 tpc-ds test The main steps of the Tpc-ds test are four parts for environment preparation, SQL statement compatibility testing, and statement modification, TPC-DS testing, and test results, where the SQL statement compatibility test will be performed under the condition that the 1GB data volume is set up with a virtual machine cluster. The Tpc-ds test is performed under 500GB data volume. 3.1

It is ideal for customers with tight budgets or customers who need 1GB basic switching capabilities and efficient, high-capacity data centers.The HP 6125G integrates the resiliency of the Intelligent Elastic Network (IRF) into the Comware operating syste

(Host), the pool has a lot of water (4GB of physical memory), there are 2 tanks (configured 2 VMS), the water tank has a certain capacity (configuration memory is 4GB), originally was empty (no boot).But now the tank 1 to raise fish, must put some water in so that the fish can survive (boot up). Minimum 1GB of memory is required. So the Tank 1 (VM1) to the pool (Host) to water (physical memory), there is enough water in the pool, to meet the requirem

. Depending on the state before the GC is optimized, if the full GC executes after the memory space remaining 300MB, then it is best to set the memory to 1GB (300MB (default program occupancy) + 500MB (the old age minimum Space) +200MB (free memory)). That means you have to set up 500MB for the old age. Therefore, if you have three execution servers, the memory is set to 1GB,1.5GB,2GB, and the results are c

and leave the rest to reporting Services REPORTSERVERTEMPDB partition For extensibility testing, Microsoft created a partitioned reportservertempdb database consisting of 10 separate 1GB files and a 1GB transaction log to improve parallelism for disk I/O operations. Partitioning the ReportServer database can also be beneficial if the snapshots in the workload have been used

DRAM, Dynamic Random Access Memory, must be constantly refreshed to save data. In addition, the row and column addresses are reused, and many of them have the page mode.SRAM, static random access memory. When powered on, data does not need to be refreshed, and data will not be lost. In addition, it is generally not reused by row and column addresses. SDRAM, synchronous DRAM, that is, data read/write requires clock synchronization.DRAM and SDRAM have a large capacity due to technical issues. Howe

) clock signals, and the third and fourth generation, due to their fast operating frequency, use a differential clock signal that can reduce interference as a synchronous clock. The clock frequency of the SDR SDRAM is the frequency of data storage, and the first generation of memory is named after the clock frequency, such as pc100,pc133, which indicates that the clock signal is 100 or 133MHz, and the data read and write rate is 100 or 133MHz.

The CL reaction time is another indicator of the fixed memory. CL is the abbreviation of CAS latency, which refers to the latency time required for memory access data, and simply the response rate of memory to the CPU's instructions. The general parameter values are 2 and 32 kinds. The smaller the number, the shorter the time required to represent the reaction. In the early PC133 memory standard, this number is set to 3, and in the new Intel redesign

This series mainly introduces the debugging methods of Linux kernel panic and abnormal restart class stability problem.In the Linux system, everything is a file, and the system is running the carrier, is a special kind of file, that is, the process. Therefore, I try to analyze the problem of the Linux kernel's panic, abnormal restart from the perspective of the process. In kernel space, the kernel itself is a privileged process that contains a series of system-level threads that maintain the ope

(smaller log records mean more records for same sized logs), how random were data modifications (random updates would need Random IO to check if pages are up to date), number of unflushed pages in InnoDB buffer pool and its size as OK as Perfo Rmance of IO subsystem. As there are so many factors, it's hard to come up and any general guidelines
