Page 39: Sas Wide Ports
7065DiskAttach.fm Draft Document for Review August 30, 2007 12:59 am SCSI configurations are sensitive to improper termination. SAS does not have such problems. SAS supports much longer cable lengths and higher maximum device attachment than SCSI. SAS environments also support attachment of SATA disk drives. In fact, SAS could be viewed as a technology to transfer SCSI commands and data across a SATA-like physical interface.

Page 45: Chapter 2. Ds3000 Introduction
DS3000 introduction Chapter 2. In this chapter, we introduce the IBM System Storage DS3000 product line and functionality. The product line consists of three storage subsystems: DS3200, DS3300, and DS3400. We describe the EXP3000 SAS disk drive enclosure as well.
Page 46: Ds3000 Products
Draft Document for Review August 30, 2007 12:59 am 2.1 DS3000 products The IBM System Storage DS3000 is a family of storage subsystems supporting up to two redundant RAID controllers and one of the following host server connectivity options: SAS on DS3200.
Page 47: Ibm System Storage Ds3200
However, to ensure sufficient cooling airflow, do not remove the failed component until you are ready to replace it with a new one. If you operate the DS3000 subsystem with certain components removed, the opening will disturb the airflow and decrease cooling efficiency.
Page 48: Ibm System Storage Ds3300
The EXP3000 is a 2U rack-mountable SAS disk drive enclosure. It supports up to 12 SAS 3.5” disk drives. If you use 300 GB disk drives, the maximum storage capacity in a single IBM System Storage DS3000: Introduction and Implementation Guide...
Page 49 EXP3000 will be 3.6 TB. You can attach up to three EXP3000 enclosures to a DS3000 storage subsystem, and this gives you maximum storage capacity of 14.4 TB. The EXP3000 enclosures connect to the drive side SAS port of the DS3000 through a 3 Gbps SAS interface.
Page 50: Premium Features
2.2 Premium features Standard configurations of DS3000 storage subsystems come with a basic set of features. If you want to enable EXP3000 attachment, 16 storage partitions, FlashCopy® and VolumeCopy, you can do this by purchasing the appropriate set of premium features.
Page 51 DS3300/DS3400 (this increases to four with the use of Software Feature Pack, as stated in the section above). The maximum number of storage partitions is 16 on all DS3000 products. Use the DS3000 Partition Expansion License to enable all 16 storage partitions.
Page 52: Ds3000 Storage Manager
Ethernet connection to the DS3000. – Iin-band This method utilizes the I/O path between a host server and the DS3000. In this case, the management station does not have direct TCP/IP connection to the DS3000, but rather communicates with the host server, (via an HBA) which acts as a gateway to the DS3000 storage subsystem.
Page 53 7065DS3KIntro.fm Draft Document for Review August 30, 2007 12:59 am Storage Manager Client (SMclient) This is the actual graphical user interface (GUI) that you use to manage the DS3000 subsystems. It has two distinct parts: Enterprise Management Window This window opens when the DS3000 Storage Manager is launched. It lists the storage subsystems it knows about.

SMcli executable, which runs the CLI commands from the operating system command prompt. Script Editor in the DS3000 Storage Manager, launched from the Enterprise Management Window. You can either run a single command at a time, or execute pre-written scripts. See Appendix C, “CLI”...
Page 55: Management Methods
SMutil is a required package on the host server. Multipath support We recommend installing two HBAs in the host servers and to use the dual controller DS3000 subsystems. This provides higher availability through I/O path and controller redundancy. However, dual path configurations will only work correctly if you install appropriate multipath driver for your particular operating system on the host server.
Page 56: In-Band Management
Draft Document for Review August 30, 2007 12:59 am In-band management In-band management method uses the I/O path between the host server and the DS3000 to transfer management commands and information. This method does not use the management Ethernet ports on DS3000 RAID controllers and access does not require a management TCP/IP network.
Page 57: Out-Of-Band Management
If the I/O paths fail, you can still access the DS3000 storage subsystem out-of-band, check the status and capture logs for effective troubleshooting. Access to both controllers is required for almost all in-band management functions.

7065Cabling.fm Draft Document for Review August 30, 2007 12:59 am Cabling Chapter 3. This chapter explains how to properly cable the DS3000 subsystems. We discuss the following cabling areas: SAS cabling between the DS3000 and EXP3000 enclosures Ethernet management cabling...
Page 64: Enclosure Id Settings
The DS3000 storage subsystem can be attached to up to three EXP3000 enclosures. For proper operation, you have to set a unique ‘enclosure ID for the DS3000 and for each of the EXP3000s. This is very important, because the enclosure ID, along with the drive’s position within the enclosure, is used to determine the hardware address of each hard disk drive.
Page 65: Exp3000 Attachment
3.3 EXP3000 attachment Here are some general rules to follow when attaching EXP3000 enclosures to a DS3000. Connect the drive-side SAS port on the DS3000 controller to the SAS In port on the EXP3000. Connect the SAS Out Port on the EXP3000 to the SAS In port on the next EXP3000.
Page 66: Exp3000 Attachment - Single Controller And Single Esm Configuration
Dual controller DS3000 We therefore recommend to use a dual controller DS3000 and two ESMs in each EXP3000. Figure 3-3 shows the SAS cable connections in this scenario. Use top-to-bottom order on the left-side controller and EXP3000 ESMs. The right-side controller and EXP3000 ESMs should be connected in bottom-to-top order.
Page 67: Exp3000 Attachment
Draft Document for Review August 30, 2007 12:59 am Figure 3-3 EXP3000 attachment If the SAS cabling on the drive side is incorrect, it will be detected by the DS3000 controller firmware. The DS3000 Storage Manager will alert you about the condition by logging a critical Major Event Log event.
Page 68: Ethernet Management Cabling
Draft Document for Review August 30, 2007 12:59 am 3.4 Ethernet management cabling Each DS3000 RAID controller contains an Ethernet management port, which you can use for out-of-band management. If you have a dual controller DS3000 subsystem, make sure the management workstation can access the management port on each controller.
Page 69: Four Host Servers Attached To A Ds3300 Subsystem
7065Cabling.fm Draft Document for Review August 30, 2007 12:59 am If the host servers only have one HBA, it is possible to attach up to six hosts to a dual controller DS3200 subsystem. However, such configuration are not recommended, as there is no redundancy for the I/O path or controller.
Page 70: Lc-Lc Fc Cable
DS3400. Each server uses two FC HBAs, so this is a fully redundant setup. If an HBA, FC cable or RAID controller fails, the host servers will still have access to logical drives. This type of setup is suitable for a two-node Microsoft Cluster Server configuration. IBM System Storage DS3000: Introduction and Implementation Guide...
Page 71 7065Cabling.fm Draft Document for Review August 30, 2007 12:59 am Host server 1 Host server 2 DS3400 Figure 3-7 Two host servers attached to dual controller DS3400 Switch-attached DS3400 As the DS3400 subsystem can support many more than two host servers, let’s consider a larger configuration.
Page 72: Four Host Servers Attached To Dual Controller Ds3400
The SAN switch must be zoned so that each HBA in a particular server is connected to a different DS3400 RAID controller. For maximum availability, you can add another SAN switch - this eliminates single point of failure on the entire I/O path. We show this in Figure 3-9. IBM System Storage DS3000: Introduction and Implementation Guide...
Page 73: Power Cabling
Figure 3-9 Redundant SAN switches 3.6 Power cabling Connecting the power cables to DS3000 subsystems and EXP3000 enclosures is a simple task. Each of the two power supplies has a power cord connector. You simply have to connect each power supply to a power source. For increased protection in case of power loss, consider connecting each power supply to a different power source.
Page 74 EXP3000 enclosure. Allow enough time for the enclosures to fully power up - this can take several minutes. 3. After all EXP3000 enclosures are up and running, power on the DS3000. Be aware that large configurations can take up to ten minutes to fully power up.
Page 75: Chapter 4. Basic Configuration
DS3400 by performing all the actions listed above. Figure 4-1 shows our sample hardware setup. We use an IBM System x 3755 host server with two FC HBAs, which is attached to a dual controller DS3400 via a SAN switch. The DS3400 is connected to an EXP3000 enclosure.
Page 76: Sample Hardware Setup
Figure 4-1 Sample hardware setup Initial Setup Tasks wizard is designed for quick and easy DS3000 installation. This wizard contains the essential steps required to get your DS3000 up and running. The tasks available through the wizard are: 1. Locate the storage subsystem 2.
Page 77: Storage Subsystem Concepts
A logical drive on the DS3000 appears as a locally attached physical disk drive to the host server. When you configure an array, you have to specify a RAID level for this array. The RAID level selection will depend on your particular performance and availability requirements.
Page 78 Figure 4-4 on page 47. This means RAID 5 offers better write performance than RAID 3, which improves greatly when using a larger number of disk drives. RAID 5 is very popular, due to its good balance between performance, availability and usable capacity. IBM System Storage DS3000: Introduction and Implementation Guide...
Page 79 7065DS3KBasicConfig.fm Draft Document for Review August 30, 2007 12:59 am Figure 4-4 RAID 5 RAID 10 As stated above, RAID 1 can only be configured on exactly two disk drives. RAID 10 is a way to expand mirroring onto four or more disk drives. It is actually a combination of mirroring and RAID 0 (striping), as shown in Figure 4-5 on page 48.
Page 80: Arrays And Logical Drives
4.1.2 Arrays and logical drives Before the host servers can start using the disk drives on the DS3000, you have to create at least one array and logical drive. An array is simply a set of physical disk drives. Each array has to be carved into one or more logical drives.
Page 81: Raid 5
The maximum number of EXP3000s supported behind the DS3000 subsystem is three. This means only arrays with up to four disk drives can be protected against enclosure loss. If you create larger arrays, enclosure loss protection will not be possible, since some enclosures will have to have more than just one Chapter 4.
Page 82: Hot Spares
Depending on your configuration, it might be wise to use more than just one hot spare. In small DS3000 configurations with a relatively low number of disk drives, one hot spare might suffice. But for larger configurations, we recommend to define several hot spares.
Page 83: Storage Partitions
7065DS3KBasicConfig.fm Draft Document for Review August 30, 2007 12:59 am drives access cannot be shared. Each logical drive has to be assigned to one server only, except when you have group of clustered servers - in this case, the whole group will have access to the same set of logical drives.
Page 84: Ds3000 Storage Manager Installation
Draft Document for Review August 30, 2007 12:59 am The standard number of storage partitions allowed is four on DS3200 and two on DS3300 and DS3400. The maximum number is 16 on all DS3000 subsystems with DS3000 Partition Expansion License.
