“Gold” Array(s)
“Silver” Array(s)
Distributed Storage
Software Defined Storage Vision:
1. Reduce cost of storage by enabling new tiers of storage. Utilize server based flash/SSD and DAS to create a tier of storage, with all the benefits of external shared storage
2. Enable integration with existing tiers of storage – Make existing SAN and NAS storage systems VM aware. i.e Enable VM-level operations natively on storage systems.
3. Automate SLA enforcement across any tier of storage through policies

High performance storage at up to 50% lower cost
Radically Simple Storage – configure and manage without complex workflows
Designed for dynamic scalability and high resiliency
Distributed Storage
Aggregated Datastore
The Virtual SAN feature clusters internal server disks to provide scalable shared storage with cloud agility & efficiency.
It’s VMware’s first major foray into delivering storage.  We’re taking a software-defined approach that is radically simpler, more scalable and agile, and lower-cost than traditional monolithic SAN or NAS storage:
   * The storage is flexible & elastic in that virtual storage can live anywhere across the pooled resource. 
   * It’s inherently a fault-replace model; any failure is handled without downtime. 
   * And, the entire system is tightly integrated with, and automated by, vCenter … and it’s specifically integrated into the application provisioning workflow so that it’ll maximize Cloud application deployment agility.
Radically Simple Storage
Automating storage provisioning & management for virtual machines
Designed For Cloud
Delivering the performance, agility and scalability demanded by current & next-gen apps
Up to 50% Lower TCO
Reducing storage capex & opex by using low-cost internal disks & eliminating complex workflow
Clusters internal server disks to provide scalable shared storage with cloud agility and efficiency.

5. What are Virtual Volumes?
Key Features
Current Paradigm
Existing SAN/NAS systems become VM-aware
Native representation of VMDKs on SAN/NAS
New API for data operations at VMDK granularity
VMDKs on LUNs
vSphere
LUNs replicated
Virtual Volumes
Customer Benefits
vSphere
Native representation of VMDKs on storage
Snapshots, replications and other operations at VM granularity on external storage
Works with existing SAN/NAS storage systems
VM level storage SLA enforcement
VMware has been investing in storage integration over the years—features like VAAI for block and NAS and VASA have increase efficiency of storage provisioning. Continuing this we are working with the storage industry on he most ambitious collaboration in the history storage industry, called Virtual Volumes (VVOLs). With this we leapfrog our competition by several years while creating the ecosystem stickyness for years to come……
Current data granularity of datastores does not fit for delivering VM specific policies using storage capabilities. What we need to more granular data management capabilities at the storage. With VVOLs, we will make existing storage system understand VMs. With native representation of VMDKs and its derrivatives, we will be able to leverage any storage capability—replication, snapshots-- that exists at VM granularity. We will be able to deliver application specific QOS leveraging storage capabilities like resource management and so on.
We are working with top 5 storage vendors for the last 2 years on this initiative.

6. Storage Policy Based Management (SPBM)
Key Features
What is Policy-based Management?
Simple policies to specify app SLA requirements
Automation of storage provisioning and VM placement across clusters
Works for any protocol : block, file and object
SLA Compliance monitoring & automatic remediation
Availability = 99.99%
DR RTO = 1 hour
Max Laten
SLA Definitions
Back up = daily
Storage capacity = 1 TB
Performance = High I/O
Security = High
Availability = 99.99%
DR RTO = 1 hour

SLA Definitions
Availability = 99%
DR RTO = 4 hour
Back up = weekly
Storage capacity = 10 TB
Performance = High I/O
Security = High
Software Defined Storage
Customer Benefits
Drastically simplify storage provisioning
Management of different storage tiers as one
Reduce storage cost by optimizing consumption
Finally….
We will create an orchestration layer which will control different storage tiers in order to deliver application specific SLAs. This will help with VMware’s vision of cloud scale provisioning by drastically simplifying storage provisioning. This will help customer create, manage and consolidate different storage tiers in order to reduce the storage cost by using right storage for right application. No more over provisioning of resources… increase utilization overall…
Application requirements are captured in simple policies.. Customer can create different services levels using these policies though self service portals.. The automated placement of VM’s storage to match the requirements would simplify how storage provisioning done for applications. Should reduce the app deployment time from days to minutes. The compliance monitoring and automatic remediation will enforce SLA automatically.

7. The Basics: Storage Abstraction in vSphere
The Datastore is the fundamental persistence abstraction.
The VMDK is the Disk abstraction
Storage Policy Based Management (SPBM) is the Control Plane
VMware is Moving Away from LUN based policy and towards VMDK based policy
For Local Storage, this is done via VSAN
For Shared Storage, this is done via VVOL
VMware is Moving Away from Raw Device Map (RDM) Disks
Thus, a VMDK Driver for Cinder

8. Cinder VMDK Driver Work Flow
As with Nova, vSphere Admin Sets Up Capacity Pools
For Storage this Means Datastores in Havana
For Icehouse, this will include SPBM
Cloud Admin Creates Cinder Volume Types
Volume Type is our MetaData Injection Vehicle
Consumer Creates New Cinder Volume
This Allows us to create meta data
Consumer Attaches Cinder Volume
We Lazy Create the VMDK Based on VM Target
VMDK Is Mounted By vSphere Against Target

9. Volume types and extra specs
Driver allows additional configuration for volume creation via extra specs in the volume type
VMDK type
Use extra spec key ‘vmware:vmdk_type’
Legal Values: ‘thin’, ‘thick’ and ‘eagerZeroedThick’
Default type is ‘thin’
Clone type
Use extra spec key ‘vmware:clone_type’
Legal Values: ‘full’ and ‘linked’
Default type is ‘full’

10. What the Heck is a “Shadow” VM?
In vSphere There is No “First Class Disk” Object. Yet.
When You Create a VMDK It Must be the Child of a VM
However, Cinder Assumes a First Class Disk
Therefore, A “Shadow” VM is inserted
<<<KARTIK, INSERT SCREEN SHOT HERE OF SHADOW VM>>>

11. VMware VMDK Driver for Cinder
DEMO

12. Current API Support Create volume Attach volume to an instance
Supported VMDK types – thin, thick, eagerZeroedThick
From scratch
From glance image
From an available source volume – full clone and linked clone
From a snapshot – full clone and linked clone
Attach volume to an instance
Detach volume from an instance
Snapshot an available volume
Delete snapshot of an available volume
Upload an available volume as glance image
Delete volume

13. Committed Roadmap Support for Storage Policy Based Management (SPBM)
Fix for SnapShot/Clone Issues with Attached Volumes
Move Core Storage Code into Oslo
Implement Remaining API Items
Incorporate Additional Icehouse APIs
Nova Support for SPBM

14. Thoughts Beyond Icehouse
Common Meta Data Model Between Cinder and Nova
Support For Application Consistent Snapshots
DR/HA Considerations in Cinder
How Do we Abstract Availability Zones?
Storage QOS
How Do We Represent Performance Contracts?
Inter DC Data Mobility Services
Alerting/Policy Violation Support, Ceilometer?
Others?
