Introducing the SteelFusion Edge Appliance
Available BlockStore Space
This section describes the available BlockStore, usable storage, and the maximum pinnable storage.
Note:
The Edge Management Console Installer displays the available physical storage using base 2 (that is, 1024 bytes
= 1 KB) rather than base 10 (that is, 1000 bytes = 1 KB). The base 10 figure is used in this table and the specification sheet
for the appliance. Please be aware of the slight difference between these figures when you are calculating the available
space for your deployment. For example, when 2.6 TB is displayed in the Edge Installer it represents 2.9 TB of available
space.
VMWare License Requirements
The following Riverbed licenses are mandatory for virtualization in the appliance:
VSPBASE
- The VSP base license to manage virtualization and VSP operations. This software that is
part of RiOS software.
VSPESXI
- License to install the embedded ESXi software.
After installing and connecting the Edge appliance, the Riverbed Licensing Portal is automatically
contacted to retrieve and install the required license keys onto the Edge appliance. If either of the licenses
have expired or are about to expire, an alarm is triggered in the Management Console Alarms page. For
detailed information about Riverbed licensing, see
“Automatic Licensing” on page 16
The Edge appliance ships with an embedded VMware ESXi vSphere Hypervisor license. This license is the
free bare-metal hypervisor that virtualizes servers so you can consolidate your applications on less
hardware. This license enables basic hypervisor functions without support for more advanced vSphere
features such as vCenter, vMotion, high availability, and so on. If you need additional features beyond what
the embedded vSphere Hypervisor license provides, you will need to purchase a license upgrade through
your VMware reseller.
There are two types of licenses that you can purchase to enable vCenter support:
SteelFusion Edge Model
BlockStore (GB)
Usable Storage (GB)
Maximum Pinnable
Storage (GB)
This refers to the space
after RAID configuration
for the entire BlockStore.
This refers to the space
available to store LUNs
after accounting for the
metadata. The metadata
uses approximately 8% of
the size of the BlockStore.
This refers to the
maximum space that can
be reserved by pinned
LUNs. This is lower than
usable storage to ensure
that a minimum amount
of space is reserved for
writes.
