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 30: Fibre Channel Defined
“Specifications” on page 21. 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.

8 GB of cache random access memory (RAM) (depending on the DS4800 model). Its host-side and drive-side fibre channel port can support fibre channel speeds of up to 4 Gb/s. Figure 1 on page 8 shows the DS4800 with front bezel in place.
Page 36 Figure 2 on page 9 shows the positions of the components in the DS4800. All DS4800 models support hot-swap RAID controllers, power supply and fan units, cache-protected batteries, and interconnect-battery units, so you can remove and replace these components without turning off the storage subsystem.
Page 37: Maximum Number Of Storage Expansion Enclosures
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.

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).

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.

10BASE-T or 100BASE-T Ethernet connection to each controller. Use the Ethernet connection to directly manage the DS4800. Use one Ethernet port for daily management of the DS4800. Reserve the other port for use by service personnel or for subsystem monitoring hardware that may be available in the future.
Page 43 Subnet Mask: 255.255.255.0 Note: For a DS4000 subsystem that has two Ethernet ports per controller, such as the DS4200, DS4700 and DS4800, use the Ethernet port that is labeled #1. 2. Start the DS4000 Storage Manager client software. The Enterprise Management window opens.
Page 44: 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 1024 MB (for models 88A/H) of Intel Pentium Xeon processor memory.
Page 45: Power Supply-Fans
100BASE-T Power supply-fans The DS4800 has two power supply and fan units. Each power supply and fan unit 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.
Page 46: Interconnect-Battery Unit
In the DS4800 Storage Subsystem, the right power supply and fan unit is linked to controller A, and the left power supply and fan unit is linked to controller B. To increase protection against power loss, always make sure that both power supply and fan units are operational.
Page 47: Interconnect-Battery Unit
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 48: 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 and fan unit has already been removed results in a loss of data access. Refer to “Replacing the interconnect-battery unit” on page 156 for complete information about the conditions required for safe removal of the interconnect-battery unit.

For example, if you have four EXP810s to be cabled to the DS4800, instead of cabling all four EXP810s to one drive port of a drive channel, distribute the enclosures to all drive ports, which results in one enclosure per drive port of a drive channel.

Page 117: Connecting Secondary Interface Cables
Do not make connections to the serial port unless you do so under the direct supervision and guidance of IBM support personnel. 2. To minimize security risks, do not connect the DS4800 in a public LAN or public subnet. Use a local private network for the DS4800 and the management station Ethernet ports.
Page 118: Configuring The Storage Subsystem
Only one Ethernet port connection from each controller is required to establish a direct (out-of-band) management connection to the DS4800 Storage Subsystem. Note: The alignment of the Ethernet and serial ports on controller A are opposite those of controller B.
Page 119: Host-Agent (In-Band) Management Method
Host-agent (in-band) management method This method requires host-agent software that you install on the host server. The host-agent software allows the DS4000 Storage Manager client program to manage the DS4000 Storage Subsystem using the same fibre channel connections between the host server and the storage subsystem. You must install at least one management station and a software agent host.

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 135 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 137 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.

The storage subsystem shuts down if the temperature rises to 70° C (158° F). v In the DS4800 Storage Subsystem, the right power supply and fan unit is linked to controller A, and the left power supply and fan unit is linked to controller B. If one power supply and fan unit has shut down and the controller that is linked to the other power supply and fan unit is removed, the DS4800 will be inoperable.
