Converting XML output from DSA logs into HTML

dsa.exe -ux -x -v -i C:\MachineType_SN_Date-Time.xml.gz

C:\Temp\dsa\dsa.exe -ux -x -v -i C:\Temp\MachineType_SN_Date-Time.xml.gz

- 취합된 DSA 툴 버전과 컨버팅 하는 DSA 툴 버전이 다를때는 일부 변환이 실패하는 듯 ...


- 로그 취합 시, “-v” 파라메터를 사용하면 변환이 필요하지 않다.
- 수행 뒤 /dsa 디렉토리를 압축하면 된다.



# /tmp/lnvgy_utl_dsa_dsala5z-10.2_portable_rhel6_x86-64.bin -v -d /dsa

# tar –cjvf dsa.bz2 /dsa/*

IBM BladeCenter H Maximum Theoretical Bandwidth




As discussed, when calculating the maximum theoretical bandwidth of the chassis, each path is evaluated supporting its highest possible data rate, which is 10Gbps half-duplex (20Gbps fullduplex) in the case of BladeCenter H.

The aggregate bandwidth is the sum of the 14 blades, each driving 20 data lanes at 10Gbps, or 280 total data lanes:

200Gbps half-duplex per blade (20 data lanes at 10Gbps each, inbound or outbound)

400Gbps full-duplex per blade (inbound and outbound data rates added together)

5.6Tbps full-duplex per chassis (14 blades x 400Gbps)
