Notes for ESS Model Summary Matrix:
1. Capacity quoted is RAID 5 effective capacity.
2. Capacity quoted is raw physical capacity and can be RAID 5, RAID 10, or a combination of both.
3. 9.1 GB drives are withdrawn from marketing.
ESS Copy Service Functions
The following ESS Copy Service Functions are supported with the iSeries:
FlashCopy
Peer-to-Peer Remote Copy (PPRC)
PPRC Extended Distance (PPRC-XD)
Use of these copy services on the iSeries or AS/400e requires creating a copy of the iSeries load source unit (LSU) on
the ESS.
#6501 Tape/Disk Device Controller attachment:
AS/400e and some iSeries servers attach to the ESS using the #6501 Tape/Disk Device Controller (SPD) adapter. In this
configuration, the ESS emulates a 9337-5xx drive, based on the size of the disk unit installed. 16 disk drives (LUNs) are
supported per #6501, with up to a maximum of 16 #6501s for 32 ports on the ESS.
#2766 PCI Fibre Channel Disk Controller and #2787 PCI-X Fibre Channel Disk Controllerattachment:
Fibre attachment to the iSeries server is either directly to an ESS (point-to-point) or by way of a 3534-1RU Fibre Channel
Managed Hub using Fibre Channel Arbitrated Loop (FC-AL) connectivity. Connection through a 3534-1RU is not
supported for the 2105 Model 800.
Each #2766 or #2787 supports 32 LUNs. Each LUN can be 8.58 GB, 17.54 GB, 35.16 GB, 36.00 GB, or 70.56 GB. 70 GB
ESS LUNs are supported by all levels of OS/400 since V5R1.
The 2109 SAN Fibre Channel Switch Models S08, S16, F16 and 3534-F08 can be used in QuickLoop mode to attach
iSeries servers to the ESS, with a minimum operating system level of OS/400 V5R1. QuickLoop is ordered as RPQ
8S0521 for the 2109.
Appropriate fibre cables must be provided to connect the iSeries to the ESS or to the SAN. Model F10 and F20 fibre
adapters have SC connectors. Model 800 fibre adapters have LC connectors. The #2766 and #2787 adapter have an LC
connector.
SAN support:
With OS/400 V5R2 full switched fabric support is available. Up to five iSeries servers can be on a single loop. Performance
considerations apply.
Further details are available in IBM eServer iSeries in Storage Area Networks: Implementing Fibre Channel Disk and Tape
with iSeries, SG24-6220.
Supported support SAN switches and directors are supported. Refer to the following Web sites for the latest information
