UCS First setup

First Time setup :
1)Configure the Fabric InterconnectA and floating IP
2)Configure Fabric Interconnect B ip
3)Chasis Discovery Policy(1-uplink,2-uplink,4uplink) configure your minimum uplink policy
4)Power Policy (n+1 or grid)
5)MAC Address Table Aging.(mostly deafult)
6) DNS serevr and time serevrs and syslog

Cisco UCS UCLI

Service profile is like a VMX file in Virtulization world which holds all logical information like number of WWN,MAC,number of Cpu,amount of memoery
and infromation without extracting it from hardware.
----------------------------------------------------------------------
UCLI COmmands :
?
show
scope
top/up
where
connect
SSH to cluster IP :
#? shows all your commands
#where (shows your peresnt location )
#show ? (will show all your operation you can use)
#scope (Zoom down to particular item and dig into  it )
#scope chassis 1 (will get you in chasis one to look into details)
#up (goes back to pervious state )
#top (goes all the way back to start of ssh ip )
#connect (Connect to NX os or frabirc to do failover and others)

Cisco UCS Project California

Cisco UCS :Project california

UCSM  Embedded ,UCS Fabric Iterconnect,UCS FAbric Exterder (40Gbps or 80 Gbps), UCS Blade server chasis,UCS Virtual Adapters,4 Power supply (N+1 or Grid redendency);8 Fans modules 1 front and 1 Back total 16 fans.


UCS Fabric Iterconnect:-

1 st gen 6100 6120(20 port+one module slot comes with 8 port license)
2 cluster port in each Fabric interconnect ,Management Console port,20 Ethernet port,expandle module SAN port and two power supplies.

and 6140(40 port+two module slot comes with 16 port license) and 2 nd gen 6200 6248UP 48 unified ports supports port channels

Fabric interconnect do not pass data .If data need to pass from one fabric to another it need to go thorugh the core in the deafault configuration fabric interconnect can act as switches if configurations are changed.

Fabric interconnect A and B are active/passive from management point.But from LAN and SAN I/O are active on both fabirc interconnects.

UCS FAbric Exterder (40Gbps or 80 Gbps)
FEX :1 gen 2100 series 2104 (4 fabric port 10 Gb ETH/FCoe)
and 2 gen 2200 series gen 2208(8 fabric prots 10 gb eth/ fcoe)

UCS Blade server chasis:
B200M2 half wdith blade 12 DIMM slots for 192GB /16gb Dimms each,2 scoket 6 cores, 1 Mezzannine Adapter
B250M2 FUll Width Blade 48 DIMM solts for 384 GB /8GB Dimms each ,2 Scket 6 cores ,2 Mezzene card
B230M2 half width Blade 32 DIMM solts for 512 Gb/16 GB dimms, 2 socket 10 cores,1 Mezzanine card, with SSD

UCS Virtual Adapters:
Support feature of hardware failure if one fails all ports fail and move to surveying fabric also called CNA since they support Fabir cannel and ethernet

M81KR (Palo) Both FCoe and Etehrnet,support 56 each  HBA and NIC Virtual Interface
VIC1280 Both FCoe and Ethernet,support 116 total   Virtual Interface reqire 2208 FEX back fo chasis
M72KR Emulex/QLogic does not support Virtual interface)
