Background information
Your organization has decided to move all of the equipment it currently has in several small data centers location at various organization offices around the country to a colocation data center near the offices where the IT department is location. This new data center has an Uptime Institute Tier 4 certification.
There are a number of reasons for making this move:
a) Most of the organization’s offices need additional space for staff.
b) The small data centers are running out of capacity for new equipment (physical space, cooling and/or power).
c) Reduce travel costs as all of the IT staff are based in one location.
d) Achieve economies of scale to reduce IT operating and capital costs (in the future).
Senior management have decided that they do not want to incur the cost of buying any new IT equipment that is not essential to the move. This means that the only new equipment will be 2 network core switches to be used to connect the server distribution layer switches to redundant WAN networks in the data center. Senior management have agreed, in writing, that downtime is acceptable as each office’s equipment is moved to accommodate this restriction on new equipment purchases.
The 2 new core network switches each have dual power supplies with a current of 2.0A at 240V. Each switch requires 2U of space in a rack. The Colocation will also allow you to rack your core switches in the sites core network racks if you wish, otherwise they need to be accounted for in your rack template. Identify these switches are Core-switch-1 and Core-switch-2
A consolidated list of the equipment that is to be moved into the colocation data center is:
a) One hundred 1U servers with redundant power supplies requiring 2A each at 240V. Identify these servers as Server-1 through Server-100. Each server required 2 cat5 for production, 1 cat5 for management, 1 cat5 for backup, 2 fiber for storage.
b) Twenty 1U network switches with redundant power supplies requiring 1.5A each at 240V. All switches have 48 network ports. Identify these switches as Switch-1 through Switch-20
c) Twenty 2U servers with redundant power supplies requiring 3A each at 240V. Identify these servers as Server-101 through Server-120. Each server required 2 cat5 for production, 1 cat5 for management, 1 cat5 for backup.
d) Six 10U blade server chassis units with 6 power supplies (3 redundant pairs). Each power supply requires 12A at 240V. Each chassis has 33 network ports Identify these units as Chassis-1 through Chassis-6. Of the 33 network ports 1 cat5 is for management and 2 are for backup. (30 for production 15x15)
e) Eight 6U storage arrays each with 4 power supplies (2 redundant pairs) each power supply requires 8A at 240V. Each storage array has 4 network ports. 2 for production, 1 for backup and 1 for management. In addition, each SAN requires 8 fiber connections. Identify these units as Storage-1 through Storage-8.
The data center is providing all of the racks already provisioned with PDUs as follows:
a) Each rack is a standard 19 inch 4-post closed rack, 42U high and includes
a. a full set of blank panels
b. Internal vertical cable management on both sides at the rear of the rack.
b) Each rack receives its power from the data center’s 2 redundant power sources provided by a bus bar.
c) Cooling is provided from the outside aisle through perforated raised floor tiles.
d) Each rack should have horizontal cable management were appropriate.
e) Each rack will have a 2u 48 port patch panel.
a. backup and server management network (iDRAC) switches are already provisioned at the site
b. the backup network is terminated using purple RJ45 keystone jacks
c. the management network is terminated using red RJ45 keystone jacks
f) Each rack has a Dell 2161 KVM (16 port) switch installed at position 21u. g) All power is 240V AC.
h) In a rack each power source has the following 1u horizontal mount PDUs:
a. One 50A PDU with 4 receptacles
b. Two 20A PDUs with 8 receptacles each
This gives a total of 6 PDUs per rack (3 on each power source).
What you are to do:
IMPORTANT: The power cables for a piece of equipment must be plugged into PDUs in the same rack as the piece of equipment is installed.
1) Determine and report the total power available on each of the redundant power sources per rack. Since all of the racks have the same power supplied to them, you only have to calculate and report this information once. (5 marks)

2) Determine and report the power required by each piece of equipment your organization will be installing in the data center. Since there are multiple pieces of equipment with the same power requirement, you only need to calculate and report this value once for each type of equipment. (5 marks)

4) Determine and report the number of racks that will be required to install all of the equipment and the total power required per rack. (8 marks) (per rack total power can be derived from the summary row in the assignment rack template)
In order to do this, you will need to:
a. assign individual pieces of equipment to racks. Implement racking rules where required.
(10 marks)
b. keep a running total of the power used per PDU or remaining PDU power. (7 marks)
c. keep track of which piece of equipment is plugged into which PDU. (5 marks)
d. keep a running total of the number of receptacles used in each PDU. (5 marks)
e. Remember that each rack is 42U high and that you need 6U for the PDUs and that you should have a cable management unit above or below each switch at minimum. (5 marks)
f. Keep a per rack port density count per switch. (5 marks)
g. Keep a per rack port density count per patch panel (5 marks)
HINT: Remember each PDU can only deliver a limited amount of power and that each PDU has a specific number of receptacles available.
5) Create rack diagrams for each rack that you populate with equipment. These diagrams need to include the equipment, PDUs, cable management units and blank panels. All equipment must be labeled with its name (as given in the Background Information section above). Do not attempt to show any cable routing or connections within each rack, this will make the diagrams to complicated. (15 marks)
There are a number of tools available to create rack diagrams suitable for this project. They include Microsoft Excel, Microsoft Visio. For consistency you will be provided with an Excel Racking Template that must be used and submitted as part of your overall solution.
HINT: This template, if used properly, provides many of the calculations needed for your summary document submission.
6) Determine and document the cooling requirements for each piece of equipment your organization is installing in the data center. Since there are multiple pieces of equipment with the same cooling requirement, you only need to calculate and report this value once for each type of equipment. (5 marks)
