  • Page 23: Storage Area Network Defined

    1.2 Storage Area Network defined The Storage Network Industry Association (SNIA) defines SAN as a network whose primary purpose is the transfer of data between computer systems and storage elements. A SAN consists of a communication infrastructure, which provides physical connections; and a management layer, which organizes the connections, storage elements, and computer systems so that data transfer is secure and robust.

  • Page 24: San Versus Network Attached Storage (Nas)

    NAS elements may be attached to any type of network. From a SAN perspective, a SAN-attached NAS engine is treated just like any other server. Figure 1-2 on page 7 illustrates the difference between a SAN and NAS. IBM TotalStorage DS300 and DS400 Best Practices Guide...

  • Page 25: San Components

    Traditional Storage Direct Attached Storage Server Storage File Server Appliance Servers Clients Clients Network Attached Storage Storage Area Network Figure 1-2 SAN versus NAS 1.4 SAN components Fibre Channel is the predominant architecture upon which most SAN implementations are built, with FICON® as the standard protocol for z/OS® systems, and FCP as the standard protocol for open systems.

  • Page 26: San Servers

    The SAN liberates the storage device so it is not on a particular server bus, and attaches it directly to the network. In other words, storage is externalized and can be functionally distributed across the organization. The SAN also enables the IBM TotalStorage DS300 and DS400 Best Practices Guide...

  • Page 27: San Interconnects

    Much of the terminology used for SAN has its origins in IP network terminology. In some cases, the industry and IBM use different terms that mean the same thing, and in some cases, mean different things.

  • Page 33 Queries to an Internet Storage Name Server (iSNS) The Internet Storage Name Server permits iSCSI targets to register with a central point. The administrator can set up discovery domains so that when a host iSCSI initiator queries the central control point for the locations of iSCSI storage controllers, only the authorized controllers are reported.

  • Page 37: Network Attached Storage (Nas)

    2.3.1 Network Attached Storage (NAS) Storage devices which optimize the concept of file sharing across the network have come to be known as NAS. NAS solutions utilize the mature Ethernet IP network technology of the LAN. Data is sent to and from NAS devices over the LAN using TCP/IP protocol.

  • Page 39: Iscsi

    Simple to implement: Because NAS devices attach to mature, standard LAN infrastructures, and have standard LAN addresses, they are, typically, extremely easy to install, operate and administer. This plug and play operation results in low risk, ease of use, and fewer operator errors, so it contributes to a lower cost of ownership.

  • Page 41: Backup

    2.4.4 Backup Backup of data on the IP Storage is the same as for any direct attach storage; that is, via any method that supports SCSI-attached volumes. A backup application running on an external server, including the one hosting the iSCSI initiator code, will control the backup of data that is physically stored on the iSCSI appliance.

  • Page 42: Network Congestion

    See 3.7, “iSCSI software and hardware” on page 58 for information specific to the DS300. There are three ways that an iSCSI initiator can be implemented in hardware and software. Each of the three approaches differs in price, performance and capabilities. IBM TotalStorage DS300 and DS400 Best Practices Guide...

  • Page 43: Software Initiator

    2.6.1 Software initiator Many operating systems have iSCSI software initiators. An iSCSI software initiator is an iSCSI driver that works with the OS TCP/IP stack, network drivers, and NICs to provide iSCSI connectivity to other iSCSI devices via the IP network. Since an iSCSI software initiator depends on the OS IP stack, if the IP stack fails or is taken down by a user, access to the remote disk is lost.

  • Page 46: Overview

    3.1 Overview The IBM TotalStorage DS300 and DS400 are entry-level, low cost workgroup storage subsystems for xSeries and BladeCenter servers. The DS300 and DS400 offer a solution for workgroup storage applications, such as file, print and Web serving, as well as remote boot storage for diskless servers.

  • Page 47: Specifications

    There are two separate SCSI buses on the midplane. Each bus is driven by a separate channel of the Adaptec 7942 chipset. Channel 0 contains drives 9 through 15, while channel 1 contains drives 0 through 5 and 8. Table 3-1 Specifications of IBM TotalStorage DS300 and DS400 disk subsystems Product DS300...

  • Page 48: Ibm Totalstorage Ds300 Disk Subsystem

    For even greater flexibility, the DS300 is designed to allow simultaneous support of a range of operating systems for xSeries and BladeCenter servers—in either single or dual-controller configurations. IBM TotalStorage DS300 and DS400 Best Practices Guide...
  • Page 49 These have the advantage of reduced costs in the server. However, they have the disadvantage of less security and increased server CPU utilization. The IBM TotalStorage DS300 is available in 3 models as shown in Table 3-2. Table 3-2 DS300 models 1701-1RL...

    Attention: It is theoretically possible to upgrade the DS300 Model 1RL to a dual controller model. The already installed controller would have to be replaced (because FRUs do not come with the cache memory and battery backup cache), and a second controller would have to be installed along with a second power supply.
