Note: The stated maximum capacity was calculated using 224 drives of the currently available 400G SATA hard drives. The DS4800 is designed to deliver up to a twofold IOP performance increase over the current DS4500 offering and represents the sixth-generation architecture of the DS4000 series family.
Page 24: Fibre Channel Defined
“Specifications” on page 19. 1. For the DS4800, each drive is considered to be a device in a fibre channel loop, even though the DS4800 might connect with SATA as well as fibre channel drives.

Figure 2. Location of components in the storage subsystem The storage subsystem provides flexibility in configuring a RAID array. (The DS4800 disk capacity is scalable from 36 GB to over 89 TB.) A minimal storage subsystem configuration would consist of one DS4800 and one DS4000 storage expansion enclosure.
Page 32: Intermixing The Exp810 And Exp710 In The Same Drive Channel
The intermix of EXP100 and EXP810 storage expansion enclosures behind a DS4800 subsystem is not currently supported. Please contact IBM reseller and representatives for such support in the future. The value 15 assumed that one of the redundant DS4800 drive channel pairs must have only EXP710 enclosures attached. Notes: 1.

However, if the 2 Gbps and the 4 Gbps DS4000 storage expansion enclosures are separated into different redundant drive channel pairs, the DS4800 ( 1 ) will support both 2 Gbps and the 4 Gbps DS4000 storage expansion enclosures at their own fibre channel speed (either 2 Gbps or 4 Gbps).

Controller A Controller B Figure 5. DS4800 configuration with 2-Gbps and 4-Gbps enclosures in different drive channel pairs Host channels Each DS4800 controller has four single-ported host Fibre Channel ports. The controllers perform link speed negotiation on each host channel Fibre Channel port (also referred to as auto-negotiation).
Page 36: Controller Memory
Each RAID controller has up to 8 GB of data cache memory, for a total of up to 16 GB cache memory per DS4800. Each RAID controller also has a total of either 512 MB (for models 80A/H, 82A/H or 84A/H) or 1024MB (for models 88A/H) of Intel Pentium Xeon processor memory.
Page 37: Power Supply-Fans
100BASE-T Power supply-fans The DS4800 has two power supply-fans. Each power supply-fan contains a power supply, a fan, and a battery charger. Each power supply provides power to the controllers by converting incoming AC voltage to the appropriate DC voltages. If one power supply-fan is turned off or malfunctions, the remaining power supply-fan can maintain electrical power and cooling to the storage subsystem.
Page 38: Interconnect-Battery Unit
Note: Although both power supply-fan units in the DS4800 chassis are identical, they are seated in the DS4800 chassis in opposite orientations. The left and right power supply-fan units are installed so that the LED column of each power supply-fan unit is located towards the interior of the DS4800, along the side of the interconnect-battery unit.
Page 39 Because the interconnect-battery unit provides electrical signal connections between the controllers, removing the interconnect-battery unit interrupts the communications between the controller units in the DS4800, resulting in a loss of communication between controllers A and B. Data access is limited to only controller A when the interconnect-battery unit is removed.
Page 40: Sfp Modules
Attention Never remove the interconnect-battery unit unless directed to do so by an IBM support representative. Removing the interconnect-battery unit after a controller or a power supply-fan has already been removed results in a loss of data access. Refer to “Replacing the interconnect-battery unit” on page 148 for complete information about the conditions required for safe removal of the interconnect-battery unit.

Take additional care when handling devices during cold weather because heating reduces indoor humidity and increases static electricity. Heat output, airflow, and cooling The maximum heat output of the DS4800 is 235 watts (803.7 BTU/hr). Each DS4800 rack-mounted unit requires an airflow of 2.5 m (87 ft.

DS4800 Storage Subsystem to ensure that the controllers complete the startup process. If the DS4800 controllers do not find any drives present during the initial power on sequence, the DS4800 will not complete the startup process. This will prevent controllers A and B from communicating with each other, and any factory-installed premium features will not be activated correctly.
Page 121 Before attempting any operations, wait at least five minutes for the storage subsystem to completely power up. Note: If your DS4800 has been shipped directly from the factory, you might have wait up to 24 hours for the battery to fully charge. You do not have to wait for the battery to fully charge in order to continue with other DS4800 setup tasks.

Page 123 Power-off overview Review the following information before you continue with the power-off procedure below. Turn off the power to each device based on the following shutdown sequence: 1. Turn off power to the host before the storage subsystem. If the host must stay powered on to support an existing network, see the operating system documentation for information about disconnecting the storage subsystem logical drives from the host before the storage subsystem is powered off.
