Storage Design Considerations: General SANApply VNX Best Practices for ESXi host Storage
Ensure Cache is Enabled for the Array and Individual LUNs
• Do not create Multiple VMFS Partitions on the same LUN
Plan to dedicate an entire LUN to a VMFS Volume
Place each LUN in a RAID group or Pool that provides the necessary performance levels

Storage Design Considerations: RDM• Use RDMs when VMFS virtual disk would become too large to
effectively manage• Use RDMs to leverage native SAN tools
SAN snapshots Direct backups Performance monitoring SAN management

• VAAI – vStorage API for Array Integration A VMware vendor neutral storage API
• Offloads ESXi storage functions to compliant storage arrays Hardware acceleration of ESXi host storage operations
Reducing CPU, memory and storage fabric bandwidth consumption More ESXi compute power available for running virtual machines
• VNX is compliant for block-based and file-based ESXi storage operations

Feature Typical Scenarios Benefits
Array Accelerated Bulk Zero
• VM Provisioning from templates• VMware Cloning• Rapid reprovisioning when older
VMs are being retired
• Background Zeroing• Improved provisioning
performance

• VASA enables VMware Storage Profiles Associates virtual disks to a
specific storage capability.• A Storage Profile used instead
of an actual storage device in vSphere management workflows (e.g. vMotion or Cloning) and the system will: Determine a target device
that matches the profile Highlight the most suitable
target for placement

Initiator Registration Records: Fibre
Number of initiators is model dependent
• Some HBAs and CNAs have two ports• Each path consumes one initiator record
An initiator is an HBA or CNA port that can access the storage system• Single path• Multipath• Alternate path
Access from a server to an SP in a storage system can be:

ESXi Server – Useful Functions and UtilitiesFunction/Utility Definitionvmkfstools Command to create and manipulate virtual
disks, file systems, logical volumes, and physical storage devices on an ESX/ESXi host.
vmware-cmd Command to provide an interface to perform operations on a virtual machine, including to retrieveinformation about the power state, register and unregister the virtual machine, set configuration variables, and manage snapshots.
resxtop Command to retrieve performance statistics. Command is included in vSphere command line interface (CLI) and is part of the vSphere Management Assistant (vMA), which is an equivalent to esxtop that runs only inside an ESX service console.
