Server power consumption

I'm referring to DL380 G7's power consumption stated as per http://www.hp.com/hpinfo/newsroom/press_kits/2010/breakingthegridlock2010/DL380G7ServerDS.pdf


There are different power supply available in this model: 460W; 750W; 1200W


In Malaysia, we can safely assume RM0.43/KWH as per http://www.tnb.com.my/business/for-commercial/pricing-tariff.html, Tariff B.


So, if we take DL380G7 with 460W, running 24x7, total per server power consumption is 4018.56KWH.


Rate per year per server, 4018.56KWH x RM0.43 = RM1272.98.


Factoring in the cooling load at 1X (2.0 PUE) puts the annual energy cost per server at RM3,455.96.


For 750W, rate per year per server is RM5634.72
For 1200W, rate per year per server is RM9015.55


You probably can take 20%-30% off from the number presented above assuming that these servers are somehow energy saving for best case.

VMware VRNI 3.5 NTP is working but not healthy

We have experienced this problem where some of the major services not started. You will not be able to connect to the vRNI via web -> https://<ip_address_of_vrni_platform>>. This probably caused by NTP insync. You need to manually start these services. Login with Consoleuser / and default password if not changed before via venter web console. Run services restart and wait for couple minutes (it took me 5-6 mins). Types of Users  User name  Password  Admin UI  admin@local Set this password in the Activate License window during installation. SSH User  support ark1nc0113ct0r CLI User  consoleuser ark1nc0ns0l3 Note It is recommended that the users change the default passwords immediately after the deployment.  Procedure 1 Navigate to  https://<vRealize Network Insight Platform IP address> .  2 Log in to the product UI with the corresponding user name and password.

Editing hosts file in iPhone/iPAD

You can now edit the hosts file with a jailbroken iPhone/iPad. Download the hosts file using tool like FileZilla. Default location is /etc/hosts. Download Notepad++ and edit the file. I've edit the file and convert it to ANSI under the Encoding menu. Once completed, upload the file back to the default location.  Try to ping the DNS... It should works!
