This shows that no contention for resources occurred. We also tested IP SAN speeds over Gigabit by creating two dedicated logical volumes and mapping one to each of the two servers. It's extremely easy to deploy, offers high levels of redundancy plus a huge expansion potential and is good value too. The DS delivered top performance in our tests and covers every storage angle.
We found it easy to deploy and capable of offering excellent levels of redundancy and security. Practices for maximising the business value of digital infrastructure Consumption-as- a-Service subscriptions. Microsoft Exchange servers break thanks to 'Y2K22' bug.

About this document This document provides instructions for installing and customizing the configuration of your IBM System Storage DS storage subsystem.
Who should read this document This document is intended for system operators and service technicians who have extensive knowledge of Fibre Channel and network technology. Click the applicable tab for the type of readme file that you are looking for: v Firmware v Storage Mgr v HBA v Tools A table displays as you click each tab. Software service and support Through the IBM Support Line, for a fee you can get telephone assistance with usage, configuration, and software problems.
Fire suppression systems A fire suppression system is the responsibility of the customer. The DS storage subsystem has ac power and fan units. Inventory checklist After you unpack the DS, verify that you have the following items. Product updates and support notifications Be sure to download the latest versions of the DS Storage Manager host software, DS storage subsystem controller firmware, storage expansion enclosure ESM firmware, and drive firmware at the time of the initial installation and when product updates become available.
Save the storage subsystem profile 2. Save the storage subsystem configuration Make sure that you save the files in a location other than in the logical drives that were created for the storage subsystem. For more information about how to complete these tasks, check the DS Storage Manager online help or the Storage Manager guide for your operating system.
After power is restored, call IBM support if any of the following conditions occur: — The storage subsystem logical drives and subsystems are not displayed in the DS Storage Manager graphical user interface GUI. Storage subsystem components The storage subsystem has the following removable components. Figure 1. Attention: 1. See Figure 2 on page 10, Figure 3 on page 10, or Figure 4 on page Connectors, switch, and enclosure ID The controllers support fiber-optic interfaces for both the host channel and drive channel ports.
AC power supply and fan units The DS storage subsystem has two removable ac power supply and fan units. Figure 5 shows power supply and fan unit components for the DS Notes: 1. Figure 5. Figure 6. Power supply and fan unit and airflow Battery units Statement Backup battery unit The backup battery unit provides power to back up the cache memory of each controller onto flash drives in the event of a power failure.
Figure 8 shows an example of SFP module with fiber-optic cable. Figure 8. Software and firmware support code upgrades To enable support for the DS, you must make sure that your system software and firmware are the correct versions. To obtain the controller firmware version: Right-click the Controller icon in the Physical View pane of the Subsystem Management window and select Properties. You must perform this step for each individual controller.
You must perform this step for each individual drive. To obtain the ESM and drive enclosure component firmware versions: 1. Specifications This section provides site specifications for the DS storage subsystem.
Area requirements The floor space at the installation site must provide enough strength to support the weight of the storage subsystem and associated equipment; sufficient space to install, operate, and service the storage subsystem; and sufficient ventilation to provide a free flow of air to the unit.
Dimensions Figure 9 shows the dimensions of the DS, which conforms to the inch rack standard. Figure 9. DS dimensions Weight The total weight of the storage subsystem depends on the number of components installed.
