Cheap v. Sphere Lab Simon Gallagher http: //vinf. net Simon Seagrave http: //www. techhead. co. uk
Agenda Why would you want to do that? Best boxes for v. Sphere Where to get them Datacentre in a box (virtualized ESX) Muti-Node TARDIS cluster Demo Performance I/O Demo FT Demo Cheap/Free SAN Storage Cheap/Free Networking Software Licensing Further Information. . .
Why? Because you can VCP study Critical home infrastructure (wife & kids 2. 0) IT is a vocation, not an occupation Production use cases Automated install testing Changes (ITIL) VUM patch testing
Best Boxes for v. Sphere Need: Cheap Low-Power!!! Quiet Options e. Bay an old Proliant Buy something cheap but less “server” Find someone else to pay for it (good luck)
Best Budget Boxes for v. Sphere New HP ML 115 G 5 / ML 110 G 5 With 160 Gb HDD, 8 GB RAM, dual/quad core ~£ 330 ML 115 G 5 is weapon of choice (AMD x 64, FT) Used HP D 530 160 Gb HDD, With 4 Gb ~£ 90 ESX 3. 5 only (not x 64) Build your own (White-box) Compatibility issues http: //virtualgeek. typepad. com/virtual_geek/2009/01/ updated-homebrew-esx-hardware-list. html Community supported H/W http: //www. vmware. com/resources/communitysupport/
Where to get them e. Bay for old kit http: //www. techhead. co. uk/hot-deals That “spares” pile – but ask 1 st!
Trolley Attached Random Datacentre of Inexpensive Servers (T. A. R. D. I. S) 2 x Physical HP ML 115 G 5 with 8 Gb RAM v. Sphere 4 Servers 1 x HP D 530 Open. Filer (1 TB i. SCSI storage, 60 Gb SSD) Cheap VLAN’able Gb. E switch 10 x virtual ESXi instances in a HA/DRS cluster 4 Gb RAM allocated to each instance (heavy overcommit!) Software L 3 router; Vyatta Trolley & luggage straps (B&Q) Approx cost to buy <£ 1, 000 Non-HA version ~£ 500 Even cheaper if you can recycle the Open. Filer box & Storage
TARDIS – Network Diagram VM Network for guest i. SCSI VLAN Physical Host Network Config VM Network for guest v. Motion. VLAN 10. 0. 0. x Admin Network VMKernel Ports For physical hosts
TARDIS – Network Diagram VMKernel Ports in ESXi Guest Virtual ESXi Guest Network These are really v. NICs Note: no need to specify VLAN tag – it is done on host
T. A. R. D. I. S Demo It’s bigger on the inside than outside v. Motion between physical host & VM ESXi (Nested VM) Host Profiles VMware Update Manager Nested Virtual Machines (configuration) FT (FT’d v. Center & Vyatta installation)
T. A. R. D. I. S Configuration Notes Separate VLAN’s for storage, v. Motion, FT VM Template with multiple v. NICs & mounted. ISO Do not clone installed ESXi/Classic Physical Host – set v. Switch to allow promiscuous mode otherwise it will not work Pay attention to max number of ESX hosts to a single shared LUN (or it will stop working) Nested VM with FT needs special VM configuration & doesn’t work brilliantly Virtual ESX servers need monitor_control. restrict_backdoor TRUE setting to run nested VMs
Storage SATA, consumer grade SSD is cost-effective Don’t expect amazing performance, but good-enough Beware of i. SCSI reservation conflicts Open. Filer HP Lefthand Virtual Storage Appliance Not free 30 -day eval available Fault-tolerance/replication & failover possible EMC Celerra Virtual Machine Free, open-source, wide hardware support Will also run as a VM (caution with HA testing) Replication possible if you are a Linux wizz Resource hungry Free Fully featured (. . more coming from EMC soon; CLARii. ON etc. ) NAS – Drobo/IX Stor. Centre
Networking There are no cheap L 3 switches Old L 3 Cisco kit is <£ 100 but not Gigabit (e. Bay) Solution Cheap So. Ho Gb. E switch that supports VLAN’ing Linksys SLM series ~£ 80 for 8 Gb. E ports & VLAN support Vyatta software appliance router (VM with multiple v. NICs Configure router VM with FT
Software Licensing VMware software is an expensive problem for the lab 60 -day evals out of the box (re-install) ESXi – but no v. Motion/etc. NFR via employer Re-using production keys; naughty The Internet; naughty No real product activation at present or viable solution to this problem from VMware – No more VMTN subscription! Microsoft Mainly for guest VMs or you could try out Hyper-V or Xen if you can’t get an eval license from VMware to use in your lab Downloadable evals Tech. Net Direct – best approach to be legal, and reasonably priced with lots of copies ~£ 300 unless you go to Tech. Ed then it’s free Open-Source Nothing to see here, move along – it’s free!
