  27. LISP @IBM

  28. Chris enjoyed a successful career with IBM spanning 21 years. His notable achievements include the role of chief architect for IBM on the multi-million dollar Lloyds TSB converged IP network, and conceiving and developing IBM’s global secure network infrastructure connecting its outsourcing clients to IBM Global Services. Chris now works as an independent consultant, and more recently at IBM, working on a data centre and network migration. • Chris Williams • Infrastructure Architect/Network Architect CEng (MIET), IBM PIC

  29. IBM and RSA Company Overviews • International Business Machines Corporation. Founded 1911. Headquarters in Armonk, New York. Multinational technology, consulting and hosting corporation. • Royal and Sun Alliance, Founded 1710. Headquartered in London. Operating in 32 countries. 17 million customers in 140 countries . Listed on the London Stock Exchange and FTSE 100 Index. • In 2001, IBM and RSA signed the first IT services agreement for IBM to manage and support the IT infrastructure and provide end-to-end service integration across all of the third party technology suppliers.

  30. Data Centre Migration Challenges for IBM Why this is an issue • To reduce the time it takes to migrate servers or applications from: • a customers data centre to an IBM data centre • an ‘inherited’ data centre to an IBM strategic data centre • within a data centre, from a legacy to a new environment (our challenge here) • Competitors who can perform a faster migration can offer a lower price to the customer and have higher margins. • Traditional migration approaches all have limitations: • Application migration • Physical move • Whole DC ‘Big Bang’ migration

  31. DC Migration without IP mobility / IP Retention Application Migration – Complexity of Ensuring Interfaces are Maintained Move application to new DC requires change of IP address and hostname Takes longer to start moving servers due to data gathering / documentation of legacy application interfaces Risk – has an interface been overlooked?

  32. DC Migration without IP mobility / IP Retention Application Migration – Complexity of Ensuring Interfaces are Maintained Complexity of ensuring interfaces are maintained - affects even non-moved / non-migrated systems DNS may not always help with legacy hard coded applications Applications local and remote may need to be amended Firewalls need to be amended Risk - Can you be sure you have the complete picture?

  33. DC Migration without IP mobility / IP Retention What is the traditional approach? • Move a server (physical move or virtual migration) and keep the IP Address and Hostname • Should be simpler process – Is this true?

  34. DC Migration without IP mobility / IP Retention Affinity Groups • Move requires understanding of server VLAN cross-patching / affinity groups if smaller units of servers to be migrated in one event Subnet B Subnet C Subnet A

  35. DC Migration without IP mobility / IP Retention Affinity Groups • Move requires understanding of server VLAN cross-patching / affinity groups if smaller units of servers to be migrated in one event Subnet B Subnet C Subnet A

  36. DC Migration – Server Physical Move Physical Move of Affinity Groups – The Reality • Physically move the server and patch into new infrastructure: • Takes longer to start moving servers due to data gathering and understanding of virtual server network interfaces. • Requires understanding of server VLAN cross-patching & affinity groups if smaller units of servers to be migrated in one event • Conflicting VLAN numbering in switch blocks – virtual server VLAN re-configuration required during migration event • Risk – has a server or VLAN cross connection been overlooked? • Server virtualisation / platform refresh is a follow on project

  37. DC Migration – Big Bang Every Server Migrated in Single Migration Event (Physical Move or Re-build) • Without a solution that enables IP mobility with IP Retention for each server then ‘Big Bang’ approach implies: • Years in Planning - takes longer to start moving servers due to data gathering and move planning • Longer storage migration cycle that requires keeping a large data set in synch over WAN (or other methods) • High risk / large service outage during migration event • Cast of thousands / large workforce required

  38. DC Migration with IP mobility / IP Retention Using LISP • We need a way to move servers with IP mobility and removing affinity group constraints of traditional approach: • Move a server (physical or virtual) and keep the IP Address and Hostname • Should be simpler process – Is this true using LISP?

  39. LISP Implementation Models We Used Model 3 • Model 1 – To use this method, would require every location to have its site WAN routers involved in the LISP ‘cloud’ • Model 2 – Located at a pinch point in the network • Model 3 – The model we intend to use - Link is across the machine room floor in our case

  40. The Migration Scope Legacy DC to New Infrastructure – Same Location

  41. LISP Infrastructure Cross Machine Room Links – ASR1002 Routers

  42. LISP Server Migration Initial State

  43. LISP Server Migration Intermediate State – Some Servers Migrated

  44. LISP Server Migration Servers Migrated

  45. LISP Server Migration Servers Migrated – HSRP Cut-Over • Migration Steps: • New DC aggregation router interface enabled & added to HRSP group • HSRP priority raised - ‘active’ router becomes New DC aggregation router • Routes injected into New DC OSPF & removed from legacy • Remove HSRP configuration on the MR-MS LISP router i/f for fully migrated subnet

  46. LISP Server Migration End State – Servers Migrated & Cut-Over to New DC Complete

  47. Why Choose LISP Why not use other Layer 2 LAN extension methods? • We looked at but rejected: • IRB(Integrated Route Bridging) • VPLS(Virtual Private LAN Service) over MPLS • There are two viable candidate technologies. They are: • OTV (Overlay Transport Virtualization) • LISP (Locator Identifier Separation Protocol) • Our Preferred Method is LISP • Because it’s a safer interconnection method. It protects against broadcast storms and spanning tree issues • Non-disruptive Layer 3 connection to existing live data centre's • Works with all server types – physical/virtual/x86/P-Series/Mainframe

  48. Cisco Services – How They Helped Us

  49. Cisco Professional Services Data Centre Replica – Cisco Lab Reading UK Replica data centre - same hardware & code levels LISP infrastructure - 4x Cisco AS1002’s Comprehensive suite of LISP function & performance tests 129Mb test report ! LISP configurations created Post implementation support
