Cooling Issues and Solutions - A Hybrid Approach to Cooling
Most Data Centers will have a mix of heat densities and therefore cooling solutions
IT Refreshes happen every 2-4 years resulting in a mix of distributed IT assets
IT management of blades and storage deployments is often in clusters
Concentrated high density loads
Older server assets may be well served by room cooling units
Leverage existing cooling assets to maintain room conditions.

End of Row▪Traditionally used▪Copper from server to access switches▪Poses challenges on highly dense server farms
▫ Distance from farthest rack to access point▫ Row length may not lend itself well to switch port density
End of Row (half row)▪Use is starting to increase given EoRchallenges▪Copper from servers to access switches▪Fiber may be used to aggregate ToR▪It addresses aggregation requirements for ToR access environments
Common Characteristics▪Typically used for modular access▪Cabling is done at DC build-out▪Model evolving from EoR to MoR▪Lower cabling distances (lower cost)▪Allows denser access (better flexibility)
▪6-12 multi-RU servers per Rack▪4-6 kW per server rack, 10Kw-20Kw per network rack▪Subnets and VLANs: one or many per switch. Subnets tend to be medium and large

▪Some customers are considering two + cluster
▪Typically:▪ ~10-15 server per rack (enterprises)▪ ~15-30 server per rack (SP)
▪ Use of either side of rack is gaining traction▪ Cabling:
▪Within rack: Copper for server to access switch▪Outside rack (uplink):
▪Copper (GE): needs a MoR model for fiber aggregation▪Fiber (GE or 10GE):is more flexible and also requires aggregation model (MoR)
▪Subnets and VLANS:▪ one or many subnets per access switch▪ Subnets tent to be small

Air Flow delivered is the same
32in 45RU Cabinet AdvantagesReduced Static pressure due to proper cable
management with more than 4-5 2RU servers per cabinet
Vertical patch panels minimizes patch cord lengths, number of sizes, & increases usable RU spacingPower cables and Network cables have good
separationAdditional room for cabling thus reducing accidental
downtime
Footprint only increases with the number of servers in a 24” cabinet.

10Gb Ethernet Pipe FC
A method for a direct mapping of FC frames over A method for a direct mapping of FC frames over Ethernet Ethernet
Seamlessly connects to FC networks Extends FC across the datacenter over the Ethernet
FCoE appears as FC to the host and the network
Preserves current FC infrastructure and management
FC frame is unchanged
Can operate over standard switches (with jumbo frames)
Priority Flow Control guarantees no-drops
Mimics FC credit-buffer system, avoids TCP
Does not require expensive off-loads
