Contain actual data files and LUNs??? Filer Disks? Data disks? Spare disks Parity disks Double parity disks Broken disks??? Partner disks??? This aggregate can be expanded. On this aggregate we will create flexible volumes that can grow and shrink in size, and that will contain actual data files and LUNs??? RAID1 mirroring??? Double Parity Disk reliability x RAID4 advantages? Combined with WAFL filesystem: on-the-fly expansion of storage no shrinking without parity recalculation Existing parity on disks Add disks to the system Traditional RAID4 has disadvantages?

NetApp solves this by filer design? Battery-backed RAM eg. Exception: different disk sizes are in different aggregates performance??? Exception: disks of different types eg. FC vs. Exception: Max 16 Tb raw capacity? When disks are added to the system, aggregates can be expanded on-the-fly Aggregates cannot shrink, however! Aggregates do not contain data directly You must create flexible volumes flexvols inside aggregates.

Volumes will contain data? Every x data disks, provide 1 or 2 parity disks? NetApp Cluster? Not like eg. FAS vs. Hardware: a heartbeat cable between both systems Hardware: systems have connection to disks of other system In case of failure of one system: other system will notice, take over the disks and boot the first system from its disks CIFS users will get disconnected, but generally client will recover Same story for LUNs: retransmissions Note: NVRAM synchronization on clusters?

What about all those Blinking Lights? Every head and every shelf have plastic quick reference cards that can be pulled out from under the front panel eg. Where to Get Help? Volumes Snapshots Qtrees? Basic Concepts Quickstart Shelf Modules?
