v. Sphere storage choices ESXi hosts datastore types NFS VMware v. Sphere VMFS File system storage technology Direct Attached Fibre Channel FCo. E i. SCSI NAS
v. Sphere datastores l Datastore l l Logical storage unit Partition, physical disk Spanning Types l l l ESXi host VMFS NFS VM content datastore VMs, templates, ISO images volume
Physical file system vs. virtual file system physical architecture virtual architecture application operating system VMware v. Sphere x 86 architecture NTFS, ext 3, UFS VMFS
v. Sphere storage adapters l Unified storage controller view l l l l SATA SCSI HW i. SCSI SW i. SCSI FC FCo. E USB
v. Sphere multipathing l Multipathing l l l Multiple paths to the device Automatic detection of the same device Path management l l l Path selection Preferred path Status
v. Sphere storage l Disk/LUN l l l Select available device Hot increase NFS l l l Server Folder Must have no_root_squash
v. Sphere storage vendor provider l l l Extends storage capability SW plug-in Storage API Storage topology, capabilities, status Vendor provider component on the array l l Server, plug-in is a client Defines system storage capabilities
v. Sphere storage profiles l List of required storage capabilities l l l User defined storage capabilities Must be enabled l l VM storage must satisfy them Must have license Check compliancy
v. Sphere RDM l Raw Device Mapping l RDM is a mapping file l l Proxy for a raw physical storage device Contains metadata for managing and redirecting disk access to the physical device Allows a VM to directly access and use the storage device Compatibility modes l l Virtual – RDM behaves exactly as a virtual disk, snapshots possible Physical – direct access to the device, no snapshots
v. Sphere – exercise l Connect all hosts to the VIRTSAN i. SCSI target l l l VIRTSAN IP = 10. 251. 0. 1 Hypervisor Y IP = 10. 251. x. y Network mask 255. 0. 0 i. SCSI IQN = iqn. 1991 -05. com. microsoft: virtsanvirtxx-target No CHAP Static discovery
