Evolution of Computer Data Storage (2) With the evolution of HDD, storage solutions evolves into 3 core enterprise storage architecture • DAS (Direct Attached Storage) • NAS (Network Attached Storage) • SAN (Storage Area Network)
History of NAS • Network-attached storage was introduced with file sharing Novell's NetWare Server in 1983. • In the UNIX world, Sun Microsystems' 1984 release of NFS allowed network servers to share their storage space with networked clients. • Inspired by the success of file servers from Novell, IBM, and Sun, several firms developed dedicated file servers. Auspex Systems was one of the first to develop a dedicated NFS server for use in the UNIX market. • A group of Auspex engineers split away in the early 1990s to create the integrated NetApp filer, which supported both Windows' CIFS and UNIX'es NFS, and had superior scalability and ease of deployment.

Storage System Basic Components NFS / CIFS / FTP / iSCSI over 1/10 GbE FCPover2/4 Gbps FC Controller1 One or moredual-FCAL-attached disk shelves, with FC or ATA drives FCAL: Fibre Channel Arbitrated Loop ATA: Advanced Technology Attachment • One controller is shown,two are typical (active/active)
Hot Swappable components • Hot swappable components and components which can be replaced with power on. • Power Supply • Cooling Unit • Hot spare disks • LCD Panel (depends)
What an active/active configuration is • An active/active configuration is two storage systems (nodes) whose controllers are connected to each other either directly or through switches. • You can configure the active/active pair so that each node in the pair shares access to a common set of disks, subnets, and tape drives, or each node can own its own distinct set of storage. • The nodes are connected to each other through a cluster adapter or an NVRAM adapter.

Why Serial-Attached SCSI, and why now? • High performance – equivalent to FC drives • Wider adoption of SAS Standard • SAS has matured – deployed in servers since 2004 • SAS expected to be in the majority by 2012 • Much higher disk density than FC for scalability requirements • Native support for SATA without need for bridging
Are SAS and FC similar? SAS disks same as FC disks – except for drive interface: • Same disk technologies • Same rotational speeds • Same reliability
Disk details on NOW • Maps drives to suppliers • Lists (most) supported shelves
NetApp Data ONTAP Network Appliance’s Data ONTAP provides a comprehensive software architecture for it’s storage appliances to ensure that storage management is simplified, and business continuance is maximised. • This architecture contains 3 main elements that work together to provide speed and reliability • Real time mechanism for process execution • WAFL file system containing NVRAM and SnapShots • RAID manager
NetApp DataONTAP Internals This graphic shows how the pieces of the NetApp software architecture fits together.
WAFL (Write Anywhere File Locator) • Data going to the disk has two parts – the data itself and information about the data, commonly referred to as metadata • Most filesystems must write data and metadata at specific location. But WAFL can write metadata and data to the first available location, thus increase performance.
NVRAM operation (1) Client Storage system GbE Dual-attached FC
operation NIC NIC ack + + BATT – NVRAM operation (2) Client Storage system • Operation is now safe in battery-backed RAM • Also in controller’s main memory, from which further processing will take place • Client free to “forget about it” – it’s done! • Purely electronic, memory-to-memory path NVRAM Main memory Mainmemory NIC = network interface card
NIC NIC + + BATT – NVRAM operation (3) Client Storage system • Consequences of operation consume main memory NVRAM Main memory Mainmemory • As many as 10 seconds elapse, during which many other ops arrive (not shown) • Consequences of this and many other ops written to disk • NVRAM is zeroed
