vCloud Architecture BrownBag
- 1. vCloud Architecture Deep Dive Chris Colotti David Hill
- 2. Who We Are Chris Colotti, VMware David Hill, VMware Global COE Global COE Consulting Architect Senior Consultant VCDX #37 CIM Lead UK Twitter @CColotti Twitter @DaveHill99 vCD on Vblock / Upgrades vCAT 2.0 contributor VMworld Presenter 08/09/11 VMworld/PEX Presenter 2011 Blogger Blogger
- 3. What We Will Talk About vCloud “Eco-System” of Components All the possible building blocks Importance of Orchestration and knowledge depth Solution in Practice Based on vCAT 2.0 Published Catalog vApp Cloning Based on 3-part “clone wars” blog posts Open Q&A on anything vCloud
- 14. Change in Management vSphere was traditionally the management layer With vCloud Director vCenter is more “Application” Layer vSphere administrators may not be vCloud Administrators Orchestration and customization may be important High availability of all components involved
- 15. Depth of Skills and Knowledge vSphere / ESX Deeper Storage Skills Deeper Networking & Firewall skills Scripting (PowerCLI) Workflows / Automation Capacity Planning Before it was ESX, vCenter and some Scripting It is about Infrastructure Management now
- 16. Example Solution in Practice
- 17. One vCloud, Two Buildings Two On-Campus Datacenters 2 vCloud Director Cells per building (4 Total Cells) Single NFS mount in Building A F5 GTM Load Balancer 1 vCenter Server per building (2 Total) Protected with vCenter Heartbeat 1 Update Manager server per building 1 Cluster per vCenter vShield Manager per building Protected use VMware Fault Tolerance Database Servers per building vCenter Orchestrator Server per building Published Master Catalogs
- 19. Published Catalogs and vApp Cloning
- 20. How Cloning Works vSphere ESX host with VM registered does the clone Block based copy when source and destination presented (Same vCenter) VAAI can help with offload Network copy when source/destination host storage is not equally presented (Same vCenter) vCloud Director “Transfer” space used when moving between vCenter servers
- 21. Logical vCloud Director View
- 22. Cloning Examples Silver to Silver = Block Based between LUNs VAAI can also improve Sliver to Gold = Network Copy between ESX hosts Silver to Bronze = vCloud Director Transfer Space (NFS) OVF Export from vCenter 1 OVF Import to vCenter 2 Similar to vCloud Connector Cell Network Design Considerations
- 23. Cell Network Considerations Today two maybe three interfaces HTTP/Console Proxy OS Management / DB Backend OS Jumbo Mgmt Frames Consider Additional Ones NFS NFS vSphere Management HTTP/Co L2 May require static or additional nsole Routes vSphere Consider Separate VLAN’s DB L2 Enable Jumbo Frames on NFS, vSphere Ports
- 24. Possible Cluster Considerations Dedicated “Catalog” Provider vDC Force all cloning load to hosts not running VM’s VAAI on Storage Challenge to force Org Catalogs to this Provider (vCO?) Within the same vCenter use a Catalog LUN Presented to all hosts even in different clusters Remember cross-vCenter will be network based copy Additional ESX Kernel Ports (No Network I/O Control)
- 25. Final Thoughts / Common Themes Window 2008 SYSPREP Re-Arm Not vCloud Specific, but be aware of it DRS Never disable it vCloud Director relies on it Supported Cell Operating Systems Check the latest list, always use what is supported NFS Share permissions Ensure “vcloud” user/group has read write to share vCloud Director and vSphere Maximums apply Combined document now Unique BIOS UUID VMware KB2006605
- 26. vCloud Maximums Item Maximum Virtual machine count 20000 Powered‐On virtual machine count 10000 Organizations 10000 Virtual machines per vApp 64 vApps per organization 500 Number of networks 7500 Hosts 2000 vCenter Servers 25 Virtual Data Centers 10000 Datastores 1024 Calalogs 1000 Source: http://www.vmware.com/pdf/vsphere5/r50/vsphere-50- configuration-maximums.pdf
- 27. Thank You! We can always use more Followers PS – Did we mention never Disable DRS with vCloud Director….. Questions Twitter @CColotti Twitter @DaveHill99
Editor's Notes
- The key to building a successful Cloud is ensuring the underlying vSphere layer is designed and built correctly. vSphere is what enables the cloud providing the virtualization layer and without it there is no cloud.
- Once we have builtvSphere, we look at bringing in vCloud Director and vShield Manager. vCloud Director is the abstraction enginge, and vShield Manager provides the functionality to enable the networking features used within a cloud environment.
