This topic describes how to configure the Dell EqualLogic SAN as the block storage
backend provider on the Storage Controller (SC).
Note: Storage SANs are deprecated as of Eucalyptus 4.4; to be removed in a future release.
- Successful completion of all the install sections prior to this section.
- The SC must be installed, registered, and running.
- You must have a paid subscription to Eucalyptus in order to use a SAN backend.
- You must have a functioning EqualLogic device available to Eucalyptus cloud.
- You must execute the steps below as a Eucalyptus administrator.
To configure Dell EqualLogic block storage for the zone, run the following commands on the CLC
Configure the SC to use Equallogic for EBS.
output of the command should be similar to:
Verify that the property value is now: 'equallogic'
Verify that the SC is listed; note that it may be in the broken
euserv-describe-services --filter service-type=storage
Enable SAN support in Eucalyptus by entering your SAN's
hostname or IP address, the username, password, and the name of the chap
(Optional) If your EqualLogic setup has dedicated paths for data access that
are different from the management IP address supplied for the
ZONE.storage.sanhost property, the following properties
must also be configured in Eucalyptus:
euctl ZONE.storage.scpaths=data-IP-address ZONE.storage.ncpaths=data-IP-address
The SC and NC data IP address might be the same; or they can be different, if
EqualLogic has multiple data interfaces.
(Optional) These properties are available for EqualLogic thin provisioning,
which can save significant space on your SAN.
These properties take effect only during new EBS volume / snapshot creation.
EBS volumes created from previously existing snapshots inherit the provisioning
settings of the parent.
euctl -s ZONE.storage.eqlthin
ZONE.storage.eqlthinprovision = Thin provision space on Equallogic SAN. Value must be true to enable and false to disable thin provisioning
ZONE.storage.eqlthinminreserve = Minimum volume reserve for a thin-provisioned volume expressed as a % of the volume size. This is the amount of immediately writable, guaranteed space reserved for the volume
Your Dell EqualLogic SAN backend is now ready to use with Eucalyptus.
