9 It maps I/O to underlying block devices efficiently when there is a large
22 spreading are hidden from initiators connected to this storage system.
25 session is connected to an eth port on a single member. Data to a LUN
28 forwarding is invisible to the initiator. The storage layout is also
29 dynamic, and the blocks stored on disk may be moved from member to
30 member as needed to balance the load.
34 is possible to set up multiple iSCSI sessions to use multiple network
35 interfaces on both the host and target to take advantage of the
37 robin algorithm to send I/O across all paths and let the storage array
38 members forward it as necessary, but there is a performance advantage to
39 sending data directly to the correct member.
50 Upper Tier - Determine which array member the I/O should be sent to.
51 Lower Tier - Load balance amongst paths to a particular member.
54 Each of these multipath devices contains the set of paths directly to
56 selectors to load balance amongst these paths. We also build a
57 non-preferred priority group containing paths to other array members for
61 a bitmap to look up the location of the I/O and choose the appropriate
62 lower tier device to route the I/O. By using a bitmap we are able to
