IS&T Data Center Services:Virtualization Strategy & Evolution

Garry ZacheissSenior Manager, Enterprise Systems

Rich LedouxTeam Leader, Windows Server Hosting

What we’ll talk about today…

A brief history of virtualization at MIT.

Why we think it’s neat.

What’s changed since last time.

Thoughts for the future.

3

…and a sales pitch.

Find the IS&T service that let’s you leverage virtualization, IS&T’s data centers and more:

DOST Co-location.

Windows Server Hosting for managed Windows systems.

Server Operations for managed UNIX/Linux systems.

Virtualization at MIT: a brief history

Began pilot offering of virtual server service in IS&T data centers in fall 2006, based on open source Xen product.

Negotiated campus-wide license for VMware desktop and data center products December 2007:

VMware Workstation/FusionVMware Virtual Infrastructure (now vSphere)

VMware Workstation/Fusion distributed free of charge to MIT Community, including Lincoln Laboratory, since Q1 2008.

VMware Virtual Infrastructure replaced Xen service in IS&T data centers Q1 2009.

Virtualization in the Data Center: Before…

6

…and after!

7

So, what’s new?

VMware releases vSphere 4 in June 2009.A great release!New features: Fault Tolerance, fully supported Storage VMotion, and more.

All IS&T-managed VMware systems updated to vSphere 4 by January 2010.

If you’re still on VI3.5, you’re missing out.

MIT adds VMware Enterprise Plus to campus-wide Enterprise License Agreement.

8-way SMP, and support for up to 256GB per VM.Support for third-party storage APIs, i.e., EMC PowerPath.Host Profiles: rapidly clone ESX hypervisors.

8

What’s new, continued.

VMware Site Recovery Manager (SRM) added to MIT’s ELA.

Works in conjunction with storage replication of your choice; adapters available for all common storage vendors.Automates disaster recovery to a remote site.

IS&T using in conjunction with EMC Mirrorview to replicate key systems.

AFSSAPMicrosoft Exchange

Replication will be available to customers of IS&T hosting services. “Coming Soon!”

9

VMware Fault Tolerance

So cool it gets its own slide.

Allows you to run a second copy of a VM as a live “hot spare” on a second ESX hypervisor.

Machine state is kept in state across the two via a dedicated network link.

In the event of hypervisor failure, the hot spare becomes live with < 1 second of unavailability.

Currently limited to single-processor VMs only.

10

Where are we going?

Original virtualization deployments were small LAMP (Linux/Apache/MySQL/PHP) apps.

Virtualization moving on to enterprise apps:

Prior to 2010:

May 2010:

Q3 FY11:

11

Evolving our storage environment

Today: all VMware deployed to EMC Clariion storage: 10k RPM Fiber Channel drives via 4 Gbps Fiber Channel connection.

Fast!Expensive!

Ongoing work to evaluate IP-based storage solutions (NAS), based on SATA drives.

NFSCIFS (aka SMB)

Initial results indicate 75-80% of the performance as existing solution, for approximately 1/3 cost.

IS&T hopes to offer a NAS storage solution for data center customers in Q3 FY11.

12

Other Virtualization Initiatives

Desktop Virtualization/VDI: Move users’ desktops to data center-hosed virtual machines

Replace desktop PCs with thin clients, OR:Extend life-cycle of desktops to 5+ years.

Ideal for public computing spaces: clusters, kiosks, etc.

IS&T is evaluating VMware View as a possible solution in this area.

“Virtual Co-lo”: IS&T-hosted, self-managed virtual machines.Making virtualization benefits available to departments who don’t need to purchase managed services.Still in exploratory phases, but let us know if this would be of interest to you or your department!

IS&T Server Hosting Services

Three different services depending on your needs:

Co-location: physical housing only; no system administration support.

Server Operations: managed UNIX/Linux systems.

Windows Server Hosting: managed Windows systems.

Server Operations Facts and Figures

500 managed systems:227 physical273 virtual16% Solaris, 84% Linux.

FY10 Q2: Virtual machines outnumber physical systems for the first time!

210 TB of SAN storage68% of managed hosts make use of SAN storage.

160 managed databases:90 Oracle70 MySQL
