VCP6-DCV Study Guide on vHersey.com IT-Muscle’s VCP 6 Delta Beta Exam Study Material David Stamen’s VCP6 Study Guide vWannabe’s VCP6-DCV Study Guide vBrownBags – Past, Present, and Future Lesson descriptions should be brief.

4 Section 3 – Configure vSphere Storage
3.1 – Connect Shared Storage Devices to vSphere 3.2 – Configure Software Defined Storage 3.3 – Create and Configure VMFS and NFS Datastore vSphere 6 Foundation Exam Topics/Blueprint How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

5 Labs/Demos Expand VMFS Datastore Create VMFS Datastore
Add an Extent to a VMFS Datastore Mount NFS Datastore Software iSCSI Multipathing Enable and Configure VSAN Create a Storage DRS Cluster

6 What’s New with vSphere 6 Storage
NFS v4.1 NFS Multipathing/Load Balancing/Security VVOLs vMotion Support with Physical RDMs VSAN 6.0 Fault Domains All Flash VSAN VMFS 3 Deprecated Example objectives At the end of this lesson, you will be able to: Save files to the team Web server. Move files to different locations on the team Web server. Share files on the team Web server.

7 Identify storage adapters and devices
SCSI (Local/Direct Attached Disks) iSCSI – Hardware and Software Fibre Channel Fibre Channel over Ethernet – Hardware and Software Ethernet (NFS) Software Defined (VSAN, VVOLs) How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

8 Identify storage naming conventions
SCSI INQUIRY Device Identifiers – Unique and persistent eui.XXXXXX, t10.XXXXXX, and naa.XXXXXXX Path-based Identifiers – Not unique and not persistent vmhbaV:Cx:Ty:Lz V = HBA Number, x = Channel, y = Target, z = LUN Legacy Identifier – Generated by ESXi host – Unique and persistent vml.XXXXXX Device Display Name – Can be modified FC - WWNN and WWPN iSCSI – iqn.year-month.tld.domain:uniqueid How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

9 Zoning and Masking Zoning controls and/or isolates paths in the FC storage fabric Defines which HBA/ports can connect to which target/ports Single-initiator-single-target is the preferred zoning practice for ESXi Storage Networking 101: Understanding Fibre Channel Zones Understanding-Fibre-Channel-Zones.htm Masking is a process that makes a LUN unavailable to some hosts Can be done on ESXi hosts (MASK_PATH module) or on array Use case – Boot from SAN How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

10 Hardware/software iSCSI initiator requirements
Hardware iSCSI HBA capable of offloading iSCSI and network processing. Dependent (VMkernel interface) or independent (no VMkernel interface) Bi-directional CHAP is not supported on independent adapters Software iSCSI Software-based initiator Requires VMkernel interface iSCSI Multipathing is not supported across HW and SW adapters How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

11 Virtual Machine File System (VMFS)
VMFS3 has been deprecated Standard (Universal) 1 MB files system block size VMFS3 datastores upgraded to VMFS5 maintain legacy block size Supports storage devices and virtual machine disks greater than 2 TB Up to 64 TB device, 62 TB virtual disk GUID Partition Table (GPT) New datastores are created with GPT format Upgraded datastores maintain MBR until expanded beyond 2 TB Supports online upgrade (VMFS3 to VMFS5) Supports online expand or extend Up to 256 VMFS datastores per host supported How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

12 Network File System (NFS)
ESXi includes NFS Clients for NFS v3 and NFS v4.1 Use only one NFS version to access a datastore No upgrade from NFS v3 to NFS v4.1 – migration only NFS datastores can be mounted read-only Supports vMotion, HA, DRS, and FT (FT not supported on NFS v4.1) Virtual disks created on NFS datastores as thin-provisioned by default unless hardware acceleration supporting Reserve Space operation is used. (NFS v4.1 does not support hardware acceleration) How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

13 NFS v4.1 Supports NFS Multipathing
Supports non-root user access when using Kerberos NFS v4.1 DOES NOT SUPPORT VMware Fault Tolerance, Storage DRS, Storage IO Control, SRM, or VVOLs NFS Hardware Acceleration NFS Shares should be exported as either v3 or v4.1 DO NOT provide both protocol versions to same share. vSphere 6 NFS v4.1 Overview How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

14 Storage DRS Datastore Clusters
Similar/interchangeable datastores Storage Capacity and Performance Load Balancing Similar to vSphere DRS Automation Levels Aggressiveness Initial Placement of virtual disks based on space and I/O workloads Migration of virtual disks based on space and I/O workloads Datastore Maintenance Mode How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

15 Multiple VMFS/NFS Datastores Use Cases
Performance – Provisioned based on performance characteristics Data Protection – Protected by array features – replication, snapshots… Recovery/Fault Domains – Number of VMs affected by datastore failure Availability – Separation of VMs and/or VM disk to reduce impact of failure Load Balancing – Balancing load and/or capacity How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

16 VMware Virtual SAN (VSAN)
3 Hosts providing storage (Disk Groups) required. At least one SSD and one HDD per Disk Group (unless all flash option). SAS/SATA HBA or RAID controller On HCL Configured in passthrough or RAID0 mode. Network Requirements Dedicated 1 GB for hybrid configurations (10GbE recommended) Dedicated/shared 10GbE for all flash configuration VMkernel adapter configured for Virtual SAN traffic type Multicast must be enabled on physical switches/routers IPv6 NOT supported for VSAN traffic How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.

17 Virtual Volumes (VVOLs)
Requires vCenter – VVOLs not supported with standalone hosts VASA Provider – Storage awareness service. Storage Container – Pool of capacity or aggregation of storage capabilities (snapshot, replication, deduplication). Protocol Endpoint – Host to VVOL communication FCoE, FC, iSCSI, NFS storage protocols IPv6 not supported NFS v4.1 not supported Virtual Datastore represents a Storage Container How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them. Presenter’s level of expertise in the subject: Briefly state your credentials in this area, or explain why participants should listen to you.
