Next Gen Datacenter

Editor's Notes

• #4: Plase 1: Many issues. Commoditized hardware and one app per server model has created a monster. Average utilization of servers ~ 15% ( Source: Gartner) Space, power, cooling challenges abound. Nearly 80% of IT costs spent just to keep the lights on…let alone innovate. Etc… Phase 2: Virtualization begins to take root in test/dev. Benefits of consolidation starting to be seen for some production apps (“Craplications”) This is goodness. Phase 3: Virtualization beginning to be seen for more than just consolidation. Moving to more business and mission critical apps. HA and recovery (DR) become focus areas. Virtualization seen as a way to eliminate planned downtime. Again, more goodness… Phase 4: Goes beyond “Agility” to policy based computing and new ways (paradigms) to deliver apps. Applications may become largely streamed and diskless. More “Utility-like” Virtualization is a key enabler and begins to become pervasively adopted. BUT… reality is that very few severs (even today) are virtualized. We’re still a long way off from seeing pervasive adoption of virtualization. Still in the low teens. (see next slide…) 79% of IT budget to keep the business running Source: Gartner Server sprawl, electricity, floor space Managing too many physical servers
• #7: We must first start with the underpinnings of XenServer and that’s the Xen hypervisor. Leverages Open Source standard Lean with < 50K lines of code Work closely with OS vendors and advisory board: Citrix, IBM, Intel, HP, Novell, Red Hat and Sun Microsystems Community patches, updates and enhancements Security CIA and NSA actively contribute to Xen XS Differentiation from Xen Open Source Management console; XenMotion; Templates; Optimization
• #9: Red text indicates new platforms that are supported with XenServer 5.
• #10: Manages Xen servers, VMs& resources -Standard windows look and feel -No single Point of Failure- like AD Multi-master replication (Master/Slave), if one fails it will promote a 2nd -Same info on all PS - No data stored in XenCenter it is a “pane of glass”
• #23: XenMotion. Check. Got it.
• #26: The power of OS Streaming technology is more evident the wider it gets deployed. Simplifies intractable problems. Now, rather than having dedicated back up sites, multiple sites can back up to the same datacenter. This creates big savings.
• #29: XenServer supports several features to guarantee service uptime in the event of infrastructure failure. Firstly, resource pools can be configured for automated high-availability. This deals with individual host failures by restarting VMs that were running on that host onto the next available machine in the resource pool. Notable features include: Peer-to-peer "self-healing" architecture ensures there is no single point of management failure. Set VM restart priorities individually, to control the order in which services are restarted in the event of host failure. Dynamic failure planning algorithms allow administrators to see how many hosts failures can be tolerated without compromising services.

• #30: VM’s on failed physical servers can automatically be restarted on other servers in the pool
• #32: Even if you are not using remote storage you can backup VMs and move them around using our import/export functionality. Again since the VMs are isolated from any hardware differences between the underlying servers you remove all of the driver headache found when moving a physical OS instance around to different boxes.
• #35: Descrição de Componentes : Citrix NetScaler = Aplication delivery controller
• #40: SmartAccess is not a feature but rather a concept. SmartAccess incorporates the following: Who is connecting? Access Gateway uses EPA scans to determine various characteristics about a client device. What is the result of the connection? Once users are authenticated, will they receive a full VPN connection, clientless access, Web Interface/Published Applications, etc? What resources can be accessed? Will users receive full access to internal network resources or only a subset of resources? How will users be able to access these resources (published apps only, FTA, etc.)?
• #41: Here is an example of providing different levels of access, based on the results of client security scans. Here, if the user doesn’t have Windows XP they are denied. Full access is given to PC’s with Prism, Symantec, a particluar registry key, and are running XP. Access is reduced as the users have fewer of these components.
