•
Support for up to 320 logical processors
& 4TB physical memory per host
•
Support for up to 1,024 virtual machines
per host
Clusters
•
Support for up to 64 physical nodes &
8,000 virtual machines per cluster
Virtual Machines
•
Support for up to 64 virtual processors
and 1TB memory per VM
Online VHDX Resize provides
VM storage flexibility
Expand Virtual SCSI Disks
1. Grow VHD & VHDX files whilst attached
to a running virtual machine
2. Then expand volume within the guest
Shrink Virtual SCSI Disks
1. Reduce volume size inside the guest
2. Shrink the size of the VHD
or VHDX file whilst the VM is running
Token-based data transfer
within the storage array

•
Rapid virtual machine provisioning and
migration
•
Faster transfers on large files
•
Minimized latency
•
Maximized array throughput
•
Less CPU and network use
•
Performance not limited by network
throughput or server use
•
Improved datacenter capacity and scale

Fibre Channel connectivity
Achieve desired levels of
networking performance
Bandwidth Management
•
Establishes a bandwidth floor
•
Assigns specified bandwidth for each type
of traffic
•
•
Helps to ensure fair sharing during
congestion
Can exceed quota with no congestion
2 Mechanisms
•
Enhanced packet scheduler (software)
•
Network adapter with DCB support

Control allocation of Storage
IOPS between VM Disks
•
Allows an administrator to specify a
maximum IOPS cap
•
Takes into account incoming &
outgoing IOPS
•
Configurable on a VHDX by VHDX
basis for granular control whilst VM is
running
•
Prevents VMs from consuming all
of the available I/O bandwidth to
the underlying physical resource
•
Supports Dynamic, Fixed
& Differencing
Duplication of a Virtual
Machine whilst Running
Export a clone of a running VM
•
Point-time image of running VM
exported to an alternate location
•
Useful for troubleshooting VM
without downtime for primary VM
Export from an existing checkpoint
•
Export a full cloned virtual machine
from a point-in-time, existing checkpoint
of a virtual machine
•
Checkpoints automatically merged into
single virtual disk
VM1 VM2
•
Utilizes available CPU resources on the
host to perform compression
•
Compressed memory sent across the
network faster
•
Operates on networks with less than 10
gigabit bandwidth available

Increased Flexibility through
Live Migration of VM Storage
• Move virtual hard disks attached
to a running virtual machine
• Manage storage in a cloud environment
with greater flexibility and control

Guest Clustering No Longer
Bound to Storage Topology
•
VHDX files can be presented to multiple
VMs simultaneously, as shared storage
•
VM sees shared virtual SAS disk
•
Unrestricted number of VMs can
connect to a shared VHDX file
•
Utilizes SCSI-persistent reservations
•
VHDX can reside on a Cluster Shared
Volume on block storage, or on
File-based storage
•
Supports both Dynamic and Fixed VHDX
Flexible choices for placement of Shared VHDX
Network Isolation & Flexibility
without VLAN Complexity
•
Secure Isolation for traffic segregation,
without VLANs
•
VM migration flexibility
•
Seamless Integration
Key Concepts
•
Provider Address – Unique IP addresses
routable on physical network
•
VM Networks – Boundary of isolation
between different sets of VMs
•
Customer Address – VM Guest OS IP
addresses within the VM Networks
•
Policy Table – maintains relationship
between different addresses & networks

Replicate to 3rd Location for
Extra Level of Resiliency
•
Once a VM has been successfully
replicated to the replica site, replica
can be replicated to a 3rd location
•
Chained Replication
•
Extended Replica contents match the
original replication contents
•
Extended Replica replication frequencies
can differ from original replica
•
Useful for scenarios such as SMB ->
Service Provider -> Service Provider DR
