The VCE VxRail Series delivers virtualization, compute, and storage in a scalable, easy to manage, hyper-converged infrastructure appliance.
VxRail Appliance is built on Intel Xeon processor-based x86 hardware with the VxRail™ Manager software bundle, and support for other value-added software from VCE, EMC, and VMware.
The VxRail Manager software bundle includes the following:
- VxRail Manager for deployment, configuration, and management
- VMware vSphere, including ESXi
- VMware vCenter Serve
- VMware Virtual SAN for storage
- VMware vRealize Log Insight
The VxRail Appliance
The VCE VxRail Appliance includes the appliance hardware, VxRail Manager, EMC Secure Remote
Services (ESRS), and access to qualified EMC software products.
The following VxRail Appliance models are available:
VxRail Appliance with Hybrid Nodes
- VxRail 60
- VxRail 120
- VxRail 160
- VxRail 200
VxRail Appliance with All-flash Nodes
- VxRail 120F
- VxRail 160F
- VxRail 200F
- VxRail 240F
- VxRail 280F
The VxRail Series offers advanced features including automatic deployment, automatic scale out, fault
tolerance, and diagnostic logging.
The VxRail Manager fully automates the installation and configuration of all nodes in an appliance after
you input the basic IP address information.
The VxRail Series provides automated scale-out functionality by detecting a new VxRail Appliance on the
network. When a new VxRail Appliance is powered on you can add it to your existing cluster or create a
new cluster, replicating the configuration, and expanding the datastore in a cluster.
Node failure tolerance
The VxRail Series supports from 0 to 3 node failures, as defined by the VSAN FTT policy.
The VxRail Series implements the standard Virtual SAN policy of one failure by default:
- An entire node can fail and the system will continue to function.
- Disk failure cannot affect more than one node. One SSD can fail or as many as three HDDs on the same node can fail.
- One network port on any node can fail without affecting the node.
- Network failover is through the virtual switch configuration in ESXi. This is automatically configured by VxRail Manager during initial setup.
Logging and log bundles
The VxRail Series provides logging and log bundles through VxRail Manager.
VxRail Appliance cluster expansion
Your VxRail Appliance cluster can be scaled in single node increments from a minimum of four nodes up
to a maximum of 32 nodes. The VxRail Manager automated installation and scale-out features make it
easy to expand your cluster as your business demands grow.
Each VxRail Appliance holds up to four nodes. If the number of nodes in a cluster is not a multiple of four, you will have a partially populated appliance chassis in the cluster. You can use the empty slots in the chassis for future expansion.
You can mix different VxRail Appliance models in the same cluster. You must adhere to the following
guidelines when deploying a mixed cluster:
- All appliances in the cluster must be running VxRail Manager version 3.5 or higher.
- First-generation appliances (sold under the VSPEX BLUE name) can be in the same cluster with VxRail Appliances, as long as they are running VxRail Manager version 3.5 or higher.
- Appliances using 1GbE networking (VxRail 60 Appliances) cannot be used in clusters with 10GbE networking.
- 6G hybrid nodes cannot be used in clusters with 12G all-flash nodes.
VxRail Appliance cluster scalability is supported to a maximum of eight appliances or 32 nodes. However, scalability to 16 appliances or 64 nodes per cluster may be allowed. You must submit a request for product qualification (RPQ) to EMC for clusters over 32 nodes.
