„Wielka dwójka”

Czyli jak działa Citrix XenApp na XenServer u dużych i mniejszych klientów

Przemek ZębikSE Citrix Systems Eastern Europe


XenServer: Design for a better utilization

Fact 1: Virtualization requires resources

Fact 2: Scalability of a server will be reduced by virtualization

By choosing the wrong virtualization solution, scalability gets unnecessarily worse

→ wrong virtualization solution = more hardware required


Underlying technology

Old: Emulation New: Paravirtualization

• Runtime binary translation

• Device emulation

• Heavyweight hypervisor (includes drivers)

• Designed for hardware assist

• Fast, enlightened I/O

• Lightweight hypervisor (native drivers)


Xen - Standard for Clouds


Why virtualize XenApp?

• Reduce hardwarefootprint in the datacenter

• Accelerate 32- to 64-bitserver transition

• Provide alternative tox64 migration

• Reduce application downtime

• Add high availability and fault tolerance

• Simplify disaster recovery

• Simplify server provisioning

• Manage single image for physical and virtual servers

• Address test and developmentscenarios

Enhance availabilityEnhance availability

Consolidate Simplify management


• Issue: 32-bit Windows can only address 4 GB RAM

• Underutilizes modern multi-core processors

Reducing XenApp Server Count

4 GB RAM exhausted

Plenty of processor (dual socket, quad-core processors) cycles still available

Best proof:customer case studies

Bitburger brewery group


• Since january 1st 2007, germany‘s strongest beer brands like Bitburger, König Pilsener, Licher, Köstritzer and Wernesgrüner are acting jointly under the umbrella group Bitburger Braugruppe

• Market leader in the gastronomy field

• Within a period of five years, the integration of the 4 corporations had been accomplished

• Distributed infrastructure with 1.800 Users at 17 different locations

• 300 Home-Offices

The customer – Bitburger Brewery

http://www.bitburger-braugruppe.de/


More than 200 physical servers in production• Citrix Presentation Server 4.5• Standard applications via published desktops• Special applications via published applications• 900 concurrent users at 17 locations + 300 in Home-Offices

Massive hardware demand for current and future requirements

Change- and patch management processes cost and time intensive• Consistent images due to high number of servers could not be granted

Initial situation



Results from Testing/POC: XenApp virtualized based on XenServer• 5 VMs with 20 users each at a CPU utilization of 50 % @ 24 GB RAM per physical host• Consolidation ratio 4:1

Usage of Essentials for XenServer Platinum• XenServer Hosts: HP BL 460c G1 QC with 2,66 GHz CPUs and 24 GB RAM• 50 VMs, davon ca. 40 in Production

900 concurrent users on XenApp with XenServer at the moment• Per Host 5 VMs with roundabout 20 users• Consolidation ratio 1:5• Usage of provisioning services for XenApp-Workload

Solution



Time savings• Configuration of new servers: 90% less effort• Rollout of Patches / Changes: 97% less effort (provisioning services)

Cost savings• Physical scalability vs. Virtual scalability: 50% (Ratio HW / VM: 1:5)• Electricity: 88% savings

Reduction of administration efforts

Reached image consistency

Delivery of SAP to 50.000 Users via XenApp & XenServer


Challenge•50.000 Users worldwide are accessing via XenApp•Reduction of 720 physical XenApp Server (Windows 2003 32Bit, maximum 4GB RAM)

•No space at datacenter (Cooling, electricity, etc.)

Citrix XenServer successfully introduced at SAP


• Before: 750 servers – After: Only 150 with XenServer

• Space requirements -75 %

• Hardware requirements -75 % (-582.000 t CO2)

• Costs for cooling -64 % (-33.000 t CO2)

Complete savings until 2011:

35% € 2,3 Mio.

XenServer and XenApp Environment


Bechtel

One of the world’s largest and most

successful global infrastructure construction

firm chooses XenServer to virtualize XenApp

• 400 servers in production

• Moving to 80% of physical servers being virtualized

• Motivation for virtualizing XenApp:

• Consolidation of 32-bit silos on 64-bit hardware

• Increasing server utilization

• Rapid provision and decommissioning of servers
