1. Thanks for this, very helpful! I very much appreciate it. You’ve helped me fill in most of the gaps on my rack spreadsheet.

2. Are these at 208V or 120V

3. Do you have specs for 1955 Blade Chassis?

4. These are for 120 V. I don’t have the specs for a 1955 Blade Chassis, but I’ll see what I can do.

5. A Dell PowerEdge 1955 blade w/ 10 blades (20 Xeon 5300 processors, 4 PSBs, 20 SATA hard drives) – on either 200, 208, or 230 voltage has the following usage:

   Total Power (Watts): 3000
   Total Power (VA): 4284
   Total Thermal (BTU/hr): 10246

6. dell has a handy tool:

7. The Dell Data Center Capacity Planner that someone posted the link for is a nice tool. Does anyone know if Sun or HP have anything similar?

8. I have a bunch of Cisco voltage stuff if you want, these really helped me with a report for my sales guy!

9. Feel free to post your Cisco voltages, I’m sure someone will want it.

10. Thanks for this, as I’m currently working on UPS sizing project now. But I’m curious how you’re getting these numbers:
    Specs on the Dell website way a PE2950 for example has a 750 Watt power supply. Is there some conversion that I’m totally missing?
    Thanks.

11. The real power and heat values are going to be very specific to the layout of your server. How many hard drives, CPUs, RAM, etc.

    I originally used a tool from a UPS vendor to find this. Others have found the DCCP from Dell useful:

    This tool from APC may also be useful for you:

    Click on “Configure by Devices”, then “Server”, Choose the server type, configure it to match yours and you now have the data you need.

12. THANK YOU!!
