• (x86) architecture data center server • computing hardware, virtualization support, switching fabric and management software• 2009.• reduce TCO(Total Cost of Ownership), • increase scalability,• increase IT staff productivity and business agility through just-in-time provisioning• mobility support for both virtualized and non-virtualized environments cohesive

platform managed as a single unit.

UNIFIED COMPUTING SYSTEM(UCS)

Unified Computing System 1

• The challenges of data center rises in terms of cost, space, power, management etc.

• integrates network, compute and virtualization to reduce these challenges.

• It has high availability, less infrastructure and simple management.

TYPES OF UNIFIED COMPUTING SYSTEM(UCS)


4Unified Computing System

As techradar.com wrote back in 2012:”By combining telephony and business data on the same network, it gives firms the ability to combine and use voice data(and video) information in their common business applications, saving and forwarding whole instant message streams, faxes, e-mails, voice phone calls or videoconferencing sessions as chunks of data”.

• That is what UCS does, it combines network, switches and virtualization for easy access and management to promote company agility

• improve IT responsiveness to rapidly changing business demands

• accelerates the delivery of new services simply, reliably, and securely on both virtualized and non-virtualized systems

6

• In March 2009, cisco announced the launch of their UCS platform.

• It was adopted by customers after seeing how Cisco successfully entered the SAN(Storage Area Network).

• knocked Brocade off their FC(Fiber Channel) perch .

• UCS used its IP datacenter cloud and ability to t propose deals that packaged both SAN MDS and IP switches with a consequent single point of support to quickly take a lead in a new market.

• 11,000 customers worldwide and an annual run rate of 822m pounds making the fastest growing product in cisco history

HOW IT CAME ABOUT


7

• server virtualization and consolidation(industry shift)

• intel Xeon 5500 processors

• create a way to map four distinct physical memory module to a single one that would be seen by the processor’s memory channel.

• 48 standard slots as opposed to the 12 found in normal servers. Scalability is up to 320 per UCS.

HOW IT CAME ABOUT


8

• FCoE(Fiber Channel Over Ethernet)• brain of the sever• centralize management with the ability to unite up to 320 servers as a

single system.• support low latency. This enables a unified network connection for each

blade server with just a wire-once 10GB Ethernet FCoE downlink. • UCS MANAGER GUIManagement is centralized using this feature


FEATURES

9

• FEX(FABRIC EXTENSIONS)• They act like a remote line card • Managed as an extension of the fabric interconnects• enables the UCS to scale to many chassis without increasing the

amount of switches.• Manages the chassis fan, power supply etc. • Everything is inherited from the upstream switch therefore allowing

you to simply plug in and play a FEX for a rack of pre cabled servers.

Pervisor kernel..VIC implements Cisco’s VM-FEX and supports Vmware’s VMDirectPath with vMotion technology The idea is centered on consolidation. Of both virtual and physical switches.VLAN is assigned to physical interface and network consistently ensured on your ESX host.

• VM-FEX• two modes.

• emulated modes - VM’s traffic is passed through the hypervisor kernel.

• high-performance mode. It utilizes the VMDirectPath I/O and bypasses the hypervisor kernel going directly to the hardware resource associated with the VM

• VMDirectPath I/O

• Hardware access directly.

• MEZZAININE I/O SLOTS• Used by a Vic(virtual interface card).• VIC provides capacity which can be sliced up into virtual interface

delivering flexible bandwidth for the UCS blade

• UCS CHASSIS

• WITHIN MINUTES

• adding or moving servers,

• installing new VM

• BUT Design

• Storage (SAN)

• L2 Networking

• L3 Networking.


WHAT TO KNOW

13

UCS VIRTUALIZED NETWORKING

• VM connected to same Vswitch in the same ESXi host• Physical switch not needed for traffic• On the same or different host• No communication between two switches• Need for external physical switch• Physical NIC as uplink to vSwitch • Traffic between vSwitch


UCS VIRTUALIZATION NETWORK

UCS VIRTUALIZATION NETWORK

Eternal physical switch

15

• The switch(fabric interconnect )- network connectivity for the chassis, blade servers and rack servers.

• FCoE-(Connect).• The switch- derived Nexus 5000 ans run Nx-OS as well as the UCS manager

software.• The FCoE component for SAN storage. • The fabric interconnect further connects to multiple fabric extenders using

VNTag(IV uplink port) to the fabric interconnects allowing up to 160 servers to be managed by one fabric interconnect or two in case of failover.

MANAGEMENT• handled by Cisco UCS manager .Software embedded into the fabric

interconnect. • Browser• Commandline (API)• Managed through vSphere

• CIMC(Cisco Integrated Management Controller)-configure and manage

• November 2012-UCS central for many domains with same model16

UCS PHYSICAL NETWORK

17

• CMS(Chassis Management Control)

• Powers up & down power supplies

• Voltages, current and temperature

• UCS blades activity

• Reads the IDs of the chassis, UCS blades, and Fabric Extenders

• Cluster in active/passive configuration.

• Chassis Management Switch –CMS• Provides connectivity to the BMC on each server blade
