I need a detail of items to be considered for connection between MDF-IDF connection?
I'm working for project which has a total of 600 outlets(POE and non POE). I have 11 IDF distributed and 1 MDF. Server and storage will be at the MDF. These are my queries
1. I have outlets for Digital phone, Analogue phone, Wireless, CCTV, ACS, Data, IPTV,PTZ camera. Please let me know which all to be considered in POE and non-POE?
2. 4 core MM Backbone cabling is considered from MDF to each IDF. What all items to be considered in this fiber patching.
3. At the MDF side Fiber patch panel is considered. Fiber splicing and termination will be done at at one side of the panel. From the other side where the routing will go?
3. In each IDF separate POE and non-POE switch are considered. How will be the connection from this IDF POE/non-POE switch to the MDF?
4. Do I need to consider Media Converter for backbone cabling.
5. How to calculate the UPS/server/storage/router ? How much to be calculated for each rack
Please help me out to design this project as I am new to this field.
Thanks

Media Convertor - Ugh... Don't trying doing this at a central location.
Devices which play media will have it's own media playback support.
UPS/server/storage/router - Since your routers + repeaters will be placed many places, just place a small UPS every where there's gear which must survive brown outs, black outs, cycle downs.
For storage, you'll have to provide detail about what you expect to store in your storage to comment.
And... 12TB drives are now $400, so simple answer is build one or more FreeNAS File Servers with lots of disk space. If disk access requires no specific speed, just build one + use your QOS settings to just set disk access at a low priority, so every one can access one large NAS + if anything else is going on, like IP camera transmission windows or video calls, NAS I/O will occur, just slower + have no effect on any other operations.
Tip: If you're new to large enterprise design, might be best for you to hire someone to assist you.

You can get close to non-POE speed with very expensive POE hardware.
Describe more about your complete runtime environment. You should have a breakdown of types of devices by quadrant...
For example, might be your IP cameras are covering a parking lot, so there will be little to no VOIP calls from that quadrant.
If you haven't done this yet. Map out you devices + quadrants, because total number of client devices/quadrant will factor into your gear selection.
Also, with many devices, you may have a requirement for being able to poll each router, WiFi host spot, repeater, etc... to determine exactly what clients are connected to each device.
You'll then use this data for congestion management.
Another factor will be choosing devices with very good QOS management.
Big Tip: When managing complex infrastructures like this, sometimes it's best to deploy small Linux devices with multiple 802.11ac cards.
This provides a fine grain QOS control (via the tc - traffic control command) + also tends to provide support for high numbers of devices/quadrant... for example, a quadrant where people are placing video IP calls (like Skype), playing external site media (audios/videos) + conducing Web interactions.
