What an IPspace is

Guidelines for vFiler unit participation in an IPspace
When you assign an IPspace to a vFiler unit, you must ensure that the vFiler unit has a unique IP address within that IPspace. After you assign an IPspace to a vFiler unit, you cannot change the IPspace without destroying the vFiler unit.

IPspace application scenario
A typical application of an IPspace is when a Storage Service Provider (SSP) needs to connect customers of companies A and B to a storage system on the SSP's premises.

Interface participation in an IPspace
If MultiStore is enabled on the storage system , all its IP-addressable interfaces, including interfaces such as interface groups and VLAN, belong to the default IPspace. The default IPspace exists automatically and cannot be renamed or destroyed.

Routing in an IPspace
A distinct routing table is maintained for each IPspace. All vFiler units participating in an IPspace share its routing table. The IP address of the interface and the IPspace identifier are used to identify the vFiler unit for which the packet is intended.

Advantages of using VLAN tagging for IPspaces
You can use VLAN tagging for IPspaces to provide traffic separation for customers, to set up more IPspaces, and to securely deliver packets to a vFiler unit in an IPspace.

HA pair and IPspaces
You can use IPspaces in an HA pair . However, you should keep in mind the requirements for naming and assigning IPspaces.

Creating an IPspace
IPspaces are distinct IP address spaces in which vFiler units reside. You create IPspaces when you need your vFiler units to have their own secure storage, administration, and routing.

IPspace and the routed daemon
When MultiStore is enabled, the routed daemon runs only in the default IPspace. The routed daemon is disabled when you create a new IPspace. It is enabled automatically after the next reboot. Optionally, you can enable the routed daemon by using the route on command, without rebooting the storage system .

Listing IPspaces on a storage system
When you want to see which interfaces are assigned to each IPspace, you can use the ipspace list command.

Removing an IP address from an interface
You must remove all the IP addresses from an interface before you can assign that interface to an IPspace.

Assigning an interface to an IPspace
To assign an interface to an IPspace, you must ensure that the interface does not have a configured IP address. You can assign only one interface at a time. If IPv6 is enabled on your storage system and you bring up an interface, an IPv6 address is automatically configured on the interface.

Destroying IPspaces
If you no longer need an IPspace, you can destroy it.

Creating a vFiler unit in a nondefault IPspace
If you are a Storage Service Provider (SSP), you might have different clients that require complete network isolation. Creating vFiler units in separate, or nondefault IPspaces ensures that the data on these vFiler units is not routed to other vFiler units or the hosting storage system in other IPspaces.
