Virtual Server Platforms Update
• Introduction
• vSphere 5:- The Technology
• vSphere 5:- The Licence Model
• vSphere 5:- What does it mean to me?
• Do I have a choice?
• Frontier Technology
• Wrap up and Q&A
Frontier Technology
• Specialists in Access, Infrastructure, Business Continuity and Data Management
• On-Premise and Cloud Solutions
• Key partners
VMware
Microsoft
Citrix
• We use these platforms in our own datacentres
vSphere 5, the technologyWhat’s new?
• V5 moves to ESXi model ESX vs ESXi confusion
• Storage DRS• vMotion, now supported over high latency links• vCenter Server Virtual Appliance• Web Client, manage vSphere from any Web browser
vSphere 5, the technologyWhat’s new?• Auto Deploy, deploy and update (patch) more
efficiently for ESXi based systems• VM format (v8), adds support for Windows Aero
graphics and USB 3• New guests: OS X 10.6• Even bigger VMs, 32 vCPUs, 1TB RAM• Profile driven storage• vCloud Director for large private cloud deployments
vSphere 5, the licence model
• Becomes vRAM centric rather than CPU cores and physical memory bound
• Some concern in the market about complexity and value
• VMware have done this to align themselves to a service provider model and to introduce a ‘fairer’ licence model more in proportion to resources used
How many vSphere licences do I need?
• As in vSphere 4 each CPU requires a licence
• vSphere 5 does not impose limits on number of cores per CPU or physical RAM per server
Example
Hosts 2
CPUs 4
vSphere Licences 4
How much vRAM do I get with my vSphere licenses?
Edition vRAM £ cost
Standard (1 CPU) – vMotion, HA 32GB 793
Enterprise (1 CPU) – FT/DRS 64GB 2,295
Enterprise Plus (1 CPU) - All 96GB 2,785
Bundles vRAM £ cost
Standard AK (8 CPU) 8x32GB 7,965
Enterprise AK(6 CPU) 6x64GB 13,950
Enterprise Plus AK (6 CPU) 6x96GB 17,550
Essentials Plus (3 hosts, 6 CPU) 6x32GB 395
Essentials (3 hosts, 6 CPU) 6x32GB 3,585
What is the vRAM pool?
• Each vSphere licence includes a vRAM entitlement
• These are pooled together over all vSphere licences of the same edition
• Example 4x Enterprise 4 CPUs 4x 64G = 256G
vRAM
How many VMs can I run with my vRAM pool?
• As many as you like, as long as you do not exceed the total vRAM entitlement of the pool
• Example, 32 VMs each configured with 4GB vRAM, but only 24 powered on = 96GB vRAM consumed from 256GB pool
How many VMs can I power on a host?
• Again as many as you like within the entitlement
• Example: 40 VMs deployed, each with 4G vRAM, distributed unevenly over 2 nodes A B Pool
CPU 2 2 4
vSphere Licences 2 2 4
Virtual Machines 4 36 40
Pooled vRAM (GB) 128 128 256
Consumed vRAM (GB) 16 144 160
What if VMs move with vMotion?
• Any VM can run on any host within a vRAM pool, so movement of VMs cannot cause more vRAM to be needed• 16 VMs on each host
• 4 move• Or they can all move
What is my vRAM pool if I have multiple vCenter Servers
• The vRAM pool can extend across multiple linked vCenter Servers. (Linked Mode is supported with vCenter Server Standard Edition)
Can I mix vSphere editions?• Yes you can, but
each edition will have its own separate vRAM pool
Ent Ent+
CPU 4 2
vSphere Licences 4 2
Pooled vRAM (GB) 256 192
Consumed vRAM (GB) 128 96
How do I expand my vRAM pool?• Here we have 4x
Enterprise = 4x64GB = 256GB
• We need some extra vRAM
• Option One: Add another Enterprise licence = 320GB
• Option Two: Upgrade all to Enterprise Plus licence = 384GB
How do I licence a new host?• Add further licences
of the same edition, or
• If you have more licences than CPUs assign licence to new CPUs, but you won’t get any extra vRAM entitlement
So what does that mean to me?• We have a few prepared scenarios
• We can quickly work through two or three more if time allows
Scenario OneNew Small Deployment• 3 hosts, with vMotion
• Significant %tage rise
• vRAM entitlement should be enough in most cases
vSphere4 vSphere5
Essentials Plus £2,660 Essentials Plus £3,585
Support £670 Support £895
Total £3,330 Total £4,480
3 hosts, 6 CPU, 768GB pRAM + vCenter for Essentials
3 hosts, 6 CPU, 192GB vRAM + vCenter for Essentials
Scenario TwoNew Mid-Size Deployment• 5 hosts, with vMotion & DRS/DPM
• Small %tage rise
• vRAM entitlement should be enough in most cases
vSphere4 vSphere5
Mid Size AK (6 CPU) £13,545 Enterprise AK (6 CPU) £13,950
Support £3,385 Support £4,430
4x Enterprise (1 CPU) £8,760 4x Enterprise (1 CPU) £9,180
Support £2,188 Support £2,292
Total £27,878 Total £29,852
10 CPU, 1,280GB pRAM, vCenter Standard
10 CPU, 640GB vRAM, vCenter Standard
Scenario ThreeRenewal of SnS and upgrade to vSphere 5• 3 dual CPU hosts, Advanced Edition
• Good News: You’re entitled to Enterprise Edition
• Bad News: When your SnS expires you have to pay the Enterprise Renewal fee
• When you upgrade to vSphere 5 you will get vRAM entitlement of 384GB
vSphere4 Advanced vSphere5 Enterprise
Production Support 1yr £425 Production Support 1yr £570
Basic Support 1yr £360 Basic Support 1yr £480
vRAM entitlement 384GB
Scenario FourUpgrade Mid-Size Standard Edition Deployment• 3x dual socket vSphere 4 Standard hosts, 200GB
vRAM used
• Upgrade to vSphere 5 Standard is FOC with active SnS
• 6 licences = 6x32GB vRAM entitlement = 192GB vRAM, insufficient to support the workload.
• Additional Standard Edition licence required, or
• Upgrade to Enterprise Edition
Scenario FiveAdd Workloads to Mid-Size Deployment• 3x dual socket vSphere 4 Enterprise hosts, 200GB
vRAM used
• Virtualise new application, Exchange 2010, 4+ roles, 32-48GB RAM per role = 192GB extra vRAM required (392GB total)
• 6 CPUs with 64GB entitlement = 384GB vRAM
• Borderline whether enough vRAM, but likely to need additional server resources anyway
How much vRAM do I get with my vSphere licenses?

Others• Red Hat
Background in Xen, but Citrix acquisition shifted to KVM focus
Many more RHEL deployments in VMware than Red Hat• Oracle
Different x86 & SPARC platforms x86 is Xen based Late to market Oracle certification! An option for Oracle database and application
environments• Parallels
Good for high density deployment of specific applications,
More likely to be seen used by service providers Can reduce overhead and OS costs
Others• With each of these Niche Players you are likely to
need a strong specific driver to veer from the mainstream leaders
