40. NetApp Storage OverView Cluster

41. Overview of High Availability Cluster: A pair of standard NetApp controllers (nodes) that share access to separately owned sets of disks, in a shared-nothing architecture Also referred to as redundant controllers Logical configuration is active-active. A pseudo active-passive config is achieved by owning all disks under one controller (except for a boot disk set under the partner controller). Dual-ported disks are cross-connected between controllers via independent Fibre Channel links High speed interconnect between controllers acts as a “ heartbeat ” link and also path for NV-RAM mirror Provides high availability in the presence of catastrophic hardware failures

42. FC High Availability Architecture Controller A Controller B LAN/SAN High speed Interconnect Controller A Disks Controller B Disks FC (shared nothing model) Active path to owned disks Standby path to partner disks

43. Mirrored NVRAM Controller A Controller B Mirrored NVRAM NVRAM When a client request is received The controller logs it in its local NVRAM The log entry is also synchronously copied to the partner’s NVRAM Acknowledgement is returned to client LAN/SAN

44. Failover mode Controller A Controller B During the failover process: NVRAM Virtual instance of Controller A IP addr or WWPN of Controller A Virtual instance of partner is created on surviving node Partner’s IP addresses (or WWPNs) are set on standby NICs (or HBAs), or aliased on top of existing NICs (or HBAs). Surviving node takes over the partner’s disk and replays it’s intended NVRAM log entries LAN/SAN NVRAM X

45. Takeover and Giveback Upon detection of failure, failover takes 40~120sec On the takeover controller, data service is never impacted and is fully available during the entire failover operation. On the failed controller, both takeover and giveback are nearly invisible to clients. NFS cares only a little (typically stateless connections) CIFS cares more (connection-based, caches, etc.) Block protocols (FC, iSCSI): depends on the tolerance of the application host HBAs are typically configured for (worst case) 2 minute timeout Takeover is manual, automatic or negotiated Giveback is manual, or automatic
