Agenda What are Virtual Volumes? Advantages of VVOLs Technical implementation of VVOL for ETERNUS Usage 1 2015 Fujitsu Technology Solutions
What are Virtual Volumes? Conventional storage VVOL storage VM consists of files (VMDK Files) on VMFS Datastore. Datastore = LUN VMDK!= LUN VM consists of LUN(VVOL) on VVOL Datastore. Datastore = Pool VMDK = LUN VM based storage management is possible. ESXi Server VM VM ESXi Server VM VM VMDK VMDK VMDK VMDK VMDK VMDK VMDK VMDK VMFS Datastore VVOL Datastore LUN VVOL (LUN) VVOL (LUN) VVOL (LUN) VVOL (LUN) Storage Container ETERNUS DX ETERNUS DX 2 2015 Fujitsu Technology Solutions
Advantages of VVOLs Allocation and consumption of storage is faster with fewer step less likely to encounter manual errors Deployment process is well suited to automation Each VM can be managed individually resulting in more optimization options for performance and protection Easy scalability through extendibility of existing vvol datastores by adding additional drives/raid groups Automated backup/snapshot configurable via vcenter 3 2015 Fujitsu Technology Solutions
Advantages of VVOLs Simplified virtual machine creating operation Only VMware administrator s operations required on management phase. No storage administrator operations required. Conventional storage Storage administrator 1 Asking VM s requirements 2 Creating LUNs 3 Setting affinities VMware administrator 4 Recognizing volumes 5 Creating datastores 6 Creating VMs by wizard VVOL storage Storage administrator No operation. VMware administrator 1 Creating VMs by Wizard (*) Creating VVOL (LUN) Setting access path Recognizing volumes (*) Using vcenter, all storage admin s operations for VM creation are done automatically. 4 2015 Fujitsu Technology Solutions
Advantages of VVOLs Profile driven storage The policy can manage a combination of QoS & AST feature. Applying this policy improves I/O performance for each VM. It reduces performance design and tuning costs. Conventional storage VVOL storage Capacity Ratio VM VM VM Virtual Storage Pool High Middle Low Band width Quality of Service High Middle Low Optimization for each VM is difficult. Automated Storage Tiering Change Capacity Ratio Capacity Ratio High Middle Low VM Band width High Middle Low High Middle Low VM Band width Quality of Service Virtual Storage Pool Capacity Ratio High Middle Low Capacity Ratio High Middle Low VM Band width Automated Storage Tiering Optimization is always possbile for each VM.

Technical implementation of VVOL for ETERNUS ETERNUS VASA Provider 8 2015 Fujitsu Technology Solutions
Technical implementation of VVOL for ETERNUS VASA Provider provides Protocol Endpoints (PE) to vsphere PEs are replacing LUNs und mount points They are handling the administration of paths und policies Can be connected via FC, iscsi und NFS ETERNUS DX only supports FC and iscsi All connected host from a cluster can access them simultaneously 9 2015 Fujitsu Technology Solutions
Technical implementation of VVOL for ETERNUS The maximum number of virtual machines that could be stored using virtual volumes is limited by the number of supported volumes of the ETERNUS The number of needed volumes for virtual machines is made up of Sample with a VM VM config (.vmx) VM Swap VM disk 1 (c:\) VM-1 1x Clone 16 x VM disk 1 (d:\) VM-1 VM-1-SnapShot 1 VM-1-SnapShot 2 Original VM 2x Snapshot's 10 2015 Fujitsu Technology Solutions
Technical implementation of VVOL for ETERNUS Volumes for virtual machines ( 2 + Number of virtual disks ) x Number of virtual machines Volumes for full backup ( Number of virtual machines x Number of virual disks ) x Clone backup Volumes for differential backup Number of virtual machines x ( Number of virtual disks + 1) x ( Number of snapshot generations to save + 1 ) 11 2015 Fujitsu Technology Solutions
Technical implementation of VVOL for ETERNUS Volumes for snapshot ( 1 + Number of virtual disks) x Number of snapshots Volumes for suspension Number of suspension Volumes for system configuration Number of volumes for Flexible Tier function* + Number of RAID groups + Number of optionally created volumes + Number of VVOL datastores + 1 *32 for DX100/200 64 for DX500/600 12 2015 Fujitsu Technology Solutions
