11 Comparing internal and external storage Server Storage Disk Drives RAID Controller Internal Storage RAID controllers and disk drives are internal to the server SCSI, ATA, or SATA protocol between controller and disks RAID controller is internal SCSI or SATA protocol between controller and disks Disk drives are external Server RAID Controller Storage Disk Drives SCSI Bus w/ external storage Introduction To Storage: Overview of the storage subsystem
12 Direct attached storage Direct Attached Storage (DAS) Storage is captive behind the server Server CPU must handle user I/O requests, but also: User-database inquiries User file/print serving Data-integrity checking Communication with other devices Data access is file system and platform dependent Costly to scale; complex to manage Clients IP Network Servers Win Linux Win Linux Unix FC FC SCSI Direct-Attached Storage (DAS)
13 DAS w/external controller and external storage Storage System Computer System CPU Memory Bus Disk Enclosure Disk Drives Disk Drives Disk Drives HBA RAID Controller Introduction To Storage: Overview of the storage subsystem
14 DAS over Fibre channel Server HBA HBA is internal Fibre Channel protocol between HBAs and external RAID controller Disk drives and RAID controller are external Storage Disk Drives RAID Controller Introduction To Storage: Overview of the storage subsystem External SAN Array
15 I/O Transfer RAID Controller Contains the smarts Determines how the data will be written (striping, mirroring, RAID 10, RAID 5, etc.) Host Bus Adapter (HBA) Simply transfers the data to the RAID controller. Doesn t do any RAID or striping calculations. Dumb for speed. Required for external storage. Introduction To Storage: Overview of the storage subsystem
16 SCSI Small Computer System Interface
17 Terminology Initiator: A SCSI device that requests an operation to be performed by another SCSI device. Host Adapter: A Controller Board that translates host I/O requests into SCSI requests. Target: A SCSI device that performs an operation as requested by an initiator. Logical Unit: A Physical or Virtual device addressable through a target. LUN: Logical Unit Number. An encoded three-bit identifier for the logical unit.
18 SCSI configuration single initiator, single target LUN0 Initiator SCSI Bus Target LUN1 LUN2
19 SCSI configuration Single initiator, multiple targets Initiator 7 T Target 0 SCSI Bus Target 1 SCSI Bus Terminator T Target n
20 SCSI configuration Multiple initiators, multiple targets Initiator 7 T Target 0 SCSI Bus Target 1 Initiator 6 T Target n
21 The SCSI I/O Channel SCSI is the dominant protocol used to communicate between servers and storage devices in open system SCSI I/O channel is a half-duplex pipe for SCSI CDBs and data Parallel bus evolution Bus width: 8, 16 bits Bus speed: 5 80 Mhz Throughput: MBps Devices/bus: 2 16 devices Cable length: 1.5m 25m A network approach can scale the I/O channel in many areas (length, devices, speed) TCP/IP Stack NIC Driver Ethernet NIC Applications Raw File System Block Device SCSI Generic Adapter Driver SCSI Adapter Half-Duplex SCSI I/O Channel SCSI Ethernet SCSI CDB: SCSI Command Descriptor Block Used to Relay SCSI Commands, Parameters, and Status between SCSI Initiators and SCSI Targets; Typically 6, 10, or 12 Byte Block IP Storage Networking FCIP/iSCSI. Steve Tegeler SCSI Initiator SCSI Target
22 Networked I/O Channel Networking the I/O Channel Same SCSI protocol (SCSI-3) carried over a network transport layer via serial implementation Transport must not jeopardize SCSI payload (security, integrity, latency) Two primary transports to choose from today: Fibre Channel and IP A networked I/O channel allows for multiple improvements: Distance limitations greatly increased High number of addressable devices Initiator Host System SCSI Channel Controller Network IP Storage Networking FCIP/iSCSI. Steve Tegeler Target and LUNs
23 Fibre channel networking Very common method for networking SCSI Fibre Channel provides high-speed transport for SCSI payload Fibre Channel SAN overcomes many shortcomings of DAS including: Addressing for up to 16-million nodes (24 bits) Loop (shared) and Fabric (switched) transport Speeds of 100 or 200 MBps (1 or 2 Gbps) Distance of up to 10km (without extenders) Support for multiple protocols Combines best attributes of a channel and a network Initiator Host System SCSI Fibre Channel HBA Fibre Channel Fabric Target IP Storage Networking FCIP/iSCSI. Steve Tegeler
24 IP: an alternate I/O transport Viable transport for I/O traffic Similar characteristics to Fibre Channel: Addressing for close to 4 billion nodes (IPv4) Primarily a switched transport (with routing) Ethernet speeds of 1/10 Gbps or various WAN speeds Support for multiple high-level protocols Cost and manageability advantages with IP IP knowledge base widespread in industry Initiator Host System SCSI IP Channel Adapter IP Network Target IP Storage Networking FCIP/iSCSI. Steve Tegeler
25 Fibre Channel

28 What is fibre channel? A high-speed transmission technology used as a peripheral channel or network backbone. FC1: Over 1G bits per second FC2: Over 2G bits per second It supports several common transport protocols like Internet Protocol (IP) and SCSI. It operates over copper and fiber optic cables at distances of up to 10 Kilometers. Up to 127 devices (SCSI: 15) Up to 10 km of cabling (3-15 ft. for SCSI) Physical interconnect can be copper or fiber optic It is supported by many suppliers.
29 Fibre channel (continued) How does it work? Serial interface Data is transferred across a single piece of medium at the fastest speed supported No complex signaling required Hot-pluggable Devices can be removed or added at will with no ill effects to data communications Provides a data link layer above the physical interconnect, analogous to Ethernet Sophisticated error detection at the frame level Data is checked and resent if necessary Introduction To Storage: Overview of the storage subsystem
30 Current standards: Performance from 266 megabits/second to over 4 gigabits/second High-bandwidth utilization with distance insensitivity. Support for multiple cost/performance levels, from small systems to super computers Ability to carry multiple existing interface command sets, including Internet Protocol (IP), SCSI, and audio and video
31 Fibre channel frame dissection Up to 2048 byte payload 4 byte checksum for each frame Introduction To Storage: Overview of the storage subsystem
32 Fibre channel What s with the funny name? Some background history required Originally developed to only support fiber optic cabling When copper cabling support was added, ISO decided not to rename the technology ISO changed to the French spelling to reduce association with fiber optics only medium Introduction To Storage: Overview of the storage subsystem
33 Fibre channel interface layers RAID Controller Disk Drive Fibre Channel Device Driver SCSI Protocol Fibre Channel Fiber Optic or Copper Cabling Introduction To Storage: Overview of the storage subsystem
34 SCSI vs. Fibre Channel Interface for internal storage to external disks Potential down time w/ SCSI Single bus RAID controller is SCSI hardware Standards: Ultra2 (80 MB/sec) Ultra 160 (160 MB/sec) Ultra 320 (320 MB/sec) Media specific (copper only) SCSI Limitations: Cables can t be any longer than 3 feet for single ended; 15 feet for LVD (low voltage differential) No more than 15 devices on a SCSI bus # of disk drives Used with SAN Lots of built-in redundancy with connections Redundant network HBA is fibre channel hardware Standards: FC1: 100 MB/sec FC2: 200 MB/sec Provides a data link layer above the physical interconnect Analogous to Ethernet FC is a network of devices It can be media independent- copper or fibre optic Fibre Channel limitations: Cable length: Up to 10 kilometers (more a limitation of cable than FC itself) Up to 127 devices # of disk drives Introduction To Storage: Overview of the storage subsystem

EMC Storage Virtualization
60 How is storage virtualized at the enterprise level? Currently Networks are virtualized using Metadata or Storage Volume Controllers. There are two types of network virtualization Metadata or Storage Volume Controllers (SVC) are placed (inband) or in the path of data flow. Metadata or Storage Volume Controllers are placed (out of band) outside the path of data flow. Source: IBM Redbook Page 8
