physical device or span several physical devices Types of datastores: ã VMware vSpheređ VMFS Host Host • NFS Datastores are used to hold virtual machine files, templates, and ISO images Datastore VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-9 About VMFS5 VMFS5: • Allows concurrent access to shared storage • Can be dynamically expanded • Uses a MB block size, good for storing large virtual disk files Host Host • Uses subblock addressing, good for storing small files: the subblock size is KB • Provides on-disk, block-level locking VMFS Datastore VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-10 Learner Objectives By the end of this lesson, you should be able to meet the following objectives: • Describe the benefits of software-defined storage • Describe per-virtual machine, policy-based policy management • Describe how VMDK data operations are offloaded to storage arrays through the use of VMware vSphere® API for Storage Awareness™ VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-81 Next-Generation Storage Next-generation storage is required to meet certain criteria Lower cost of storage Compute Management Reduce manual processes around storage management Storage/Availability Network/Security Handle explosive data growth Respond to new data access and

Customers have major concerns about storage Storage management is too complex Cost of  “Setting up storage requires too much time.”  “Data operations are LUN-centric We want virtual machine-focused operations.” Cost of ownership is tooownership high  “We overprovision storage.” SLAs are too difficult to ensure  “SLAs cannot ensure predictable performance.” is too high  “Our storage budget keeps going up.”  “Troubleshooting is very hard.” VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-84 VMDKs as Native Objects Traditional Model VMware VMware vSphere vSphere Virtual volumes VMDKs and VMDK Data Operations Offloaded to Storage Arrays Replication Snapshots Caching Encryption De-duplication VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-85 Storage Array Requirements Virtual volumes require that the following criteria be met to function properly: • A storage array compatible with vSphere API for Storage Awareness 2.0 • Must implement vSphere API for Storage Awareness to create the storage provider for virtual volumes: – Firmware – Virtual appliance – Physical appliance • Use APIs to handle offloaded data services on the virtual volumes • Enable fine capabilities • Publish a VASA provider that runs on the array through a URL VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-86 Storage Administration vSphere vSphere PE No need to configure LUNs or NFS shares Set up a single I/O access called a protocol endpoint, to set up a data path from virtual machines to virtual volumes Set up a logical entity, called storage container, to group virtual volumes for easy management VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-87 Protocol Endpoints The protocol endpoint is set up by the storage administrator The protocol endpoint is part of the physical storage fabric It is treated like a LUN vSphere vSphere The protocol endpoint supports typical SCSI and NFS commands Virtual volumes are bound and unbound to a protocol endpoint: ESXi or VMware vCenter Server™ initiates the bind and unbind operation PE Existing multipathing policies and NFS topology requirements can be applied VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-88 Storage Containers In vCenter Server, the storage containers are represented by virtual datastores: • A storage container is configured by the storage vSphere vSphere administrator • A storage container is a logical grouping of virtual volumes • A storage container’s capacity is limited only by the hardware capacity PE • You must set up at least one storage container per storage system You can have multiple storage containers per array • You assign capabilities to storage containers VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-89 Using Virtual Volumes A vendor provider is a storage provider based on vSphere API for Storage Awareness that allows the array to export its capabilities and present them to vSphere A protocol endpoint is a replacement for the traditional LUN and can be accessed with typical NFS or SCSI methods Virtual Volumes datastores are created on the protocol endpoint: • Virtual volumes are objects created on the datastore Register a storage provider in vCenter Server Discover protocol endpoints (iSCSI, NFS, and so on) Create Virtual Volumes datastores VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-90 Bidirectional Discovery Process Protocol Endpoint Storage Container Storage administrator sets up a protocol endpoint Storage administrator sets up a storage container of defined capacity and capability ESXi host discovers the protocol endpoint during a scan VASA provider discovers the storage container and reports to vCenter Server vSphere API for Storage Awareness is used to bind virtual volumes to the protocol endpoint Virtual volumes are created in a Virtual Volumes datastore VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-91 Storage-Based Policy Management (1) Storage-based policy management helps ensure that virtual machines receive their required performance, capacity, and availability Per-virtual machine storage policies Policies set based on application

of software-defined storage • Describe per-virtual machine, policy-based policy management • Describe how VMDK data operations are offloaded to storage arrays through the use of VMware vSphere® API for Storage Awareness™ VMware vSphere: Install, Configure, Manage © 2015 VMware Inc All rights reserved 6-94 Key Points • You use VMFS datastores to hold virtual machine files • Shared storage is integral to vSphere features such as vSphere vMotion, vSphere HA, and vSphere DRS • Virtual SAN enables low-end configurations to use vSphere HA, vSphere vMotion, and vSphere Storage vMotion without requiring external shared storage • Virtual SAN clusters direct-attached server disks to create shared storage designed for virtual machines • Virtual Volumes is a storage management approach that enables administrators to differentiate virtual machine services per application • Key components of the Virtual Volumes functionality include virtual volumes, VASA providers, storage containers, protocol endpoints, and virtual datastores Questions?
