VCE Vblock™ Systems Series 700 Architecture Overview

Virtualization components

Virtualization overview

VMware vSphere is the virtualization platform that provides the foundation for the private cloud. The core

VMware vSphere components are the

VMware vSphere Hypervisor ESXi and VMware vCenter Server for

management.

The hypervisors are deployed in a cluster configuration and can scale up to 32 nodes per cluster. The cluster

allows dynamic allocation of resources, such as CPU, memory, and storage. The cluster also provides

workload mobility and flexibility with the use of VMware vMotion and Storage vMotion technology.

VMware vSphere Hypervisor ESXi

The VMware vSphere Hypervisor ESXi runs in the AMP and in the Vblock system. This lightweight hypervisor

requires very little space to run (less than 6 GB of storage required to install) and has minimal management

overhead. ESXi does not contain a console operating system. ESXi is booted from a dedicated SAN volume to

provide stateless computing within a Vblock system. The stateless hypervisor is not currently supported.

Cluster configuration

ESXi hosts and their resources are pooled together into clusters. These clusters contain the CPU, memory,

network, and storage resources available for allocation to virtual machines. Clusters can scale up to a

maximum of 32 hosts. Clusters can support thousands of virtual machines.

The clusters can also support a variety of Cisco UCS blades running inside the same cluster.

Note:

Some advanced CPU functionality might be unavailable if more than one blade model is running in a

given cluster.

Datastores

Vblock systems support a mixture of datastore types: block level storage using VMFS or file level storage

using NFS.

The maximum size per VMFS5 volume is 64 TB (50 TB VMFS3 @ 1 MB). Each host/cluster can support a

maximum of 255 volumes.

VCE optimizes the advanced settings for ESXi hosts that are deployed in Vblock systems to maximize the

throughput and scalability of NFS datastores. Vblock systems currently support a maximum of 256 NFS

datastores per host.

Virtual networks

Virtual networking in the AMP uses the VMware standard vSwitch. Virtual networking in Vblock systems is

managed by the Cisco Nexus 1000v distributed virtual switch.
