IBM® supports attachment of SMP IBM
BladeCenter® blade and System x™
models to an IBM i solution via an iSCSI network.
This implementation uses iSCSI host bus adapters (iSCSI HBAs) and provides systems management
and disk consolidation features.
Attachment of BladeCenter blade and System x models via iSCSI HBAs requires IBM i 5.4 or later
plus a minimum cumulative PTF package and additional PTFs.
See the IBM i PTFs page for details.

Table footnotes:
1 Some of the System x iSCSI HBA and IBM i iSCSI HBA cards look identical,
but they have different firmware and function, so they are not interchangeable. Use the CCIN numbers shown in the table above to distinguish which cards are used in which system.
The CCIN is shown on a label located on the tail stock of the card.
2 Supports copper or fiber ports, depending on the BladeCenter I/O modules that are used in bays 3 and 4.
Both I/O module bays 3 and 4 must contain BladeCenter I/O modules
and at least 2 IBM i iSCSI HBAs are required in order to use both ports for disk I/O.
3 Initiator iSCSI HBA BIOS and firmware updates may be required for a successful installation.
See the Note 1 on the
BladeCenter and System x models supported with iSCSI web page.
4 Use LC duplex connectors for the iSCSI HBA fiber ports.
5 Customers ordering part number 32R1923 should receive a card that shows part number 32R1925 on the adapter card sticker label. Only adapters with part number 32R1925 on the adapter sticker label are supported with this solution.
Attention: Adapters with part number 26K6489 on the adapter sticker label are not supported and will not work. They should be returned and replaced with adapters that have part number 32R1925 on the adapter sticker label.
Note: Adapters with part number 32R1925 on the adapter sticker label are supported, but may have a Vital Product Data (VPD) part number of either 32R1925 or 26K6489. Both are valid VPD part numbers. The VPD can be viewed from the Management Module web interface. To identify a supported 32R1925 labeled adapter with the 26K6489 VPD, verify that the Manufacture Date (Manuf. Date) is 0806 or newer. Adapters with a VPD of 26K6489 with manufacturing dates of 0706 or earlier are not supported.
6 For this IBM i iSCSI solution, System x PCIe iSCSI HBAs are not supported for use with VMware ESX and Linux.

The following documents contain information about planning and implementing Windows, VMware ESX and Linux on BladeCenter and System x servers that are attached to the IBM i via iSCSI HBAs:
 |
|
IBM i integration with BladeCenter and System x provide storage virtualization and innovative options that can enable customers to enhance the reliability and recoverability of their Windows, VMware ESX or Linux server environment. If a Windows, VMware ESX or Linux server fails, you can quickly and easily switch the server's storage spaces to another "hot spare" server without restarting your IBM i. See the Hot spare support page for additional information.

1See Minimum System i firmware that is required when using iSCSI HBAs.
2 Each BladeCenter blade or System x model that is integrated with the IBM i platform
using iSCSI HBAs will consume resources on the IBM i platform. The actual number
of blade or System x models that a Power server can support
will depend on the available IBM i resources and the applications on the blade or System x models.
See Chapter 17, Integrated BladeCenter® and System x™ Performance in the
System i Performance Capabilities Reference (1.6 MB) to determine the IBM i platform impact of integrating BladeCenter blade or System x models.
|
 |
 |
| The iSCSI solution is very flexible in the way that blade or System x models
are connected to the IBM i platform.
The total number of iSCSI HBAs that are supported for each Power server were listed in the previous section.
The following are additional limits for various pieces of the solution:
|
 |
| · |
Each IBM i iSCSI HBA may provide storage access
for up to 8 blade or System x models simultaneously1.
|
 |
| · |
Each IBM i iSCSI HBA may provide up to 8 virtual Ethernet access points1.
This could be 8 blade or System x models using just the point-to-point virtual Ethernet,
two blade or System x models with each using three virtual Ethernet networks
in addition to the point-to-point virtual Ethernet, or some other combination.
|
 |
| · |
For each blade or System x model, storage access may be distributed over up to 4 IBM i iSCSI HBAs.
|
 |
| · |
For each blade or System x model, virtual Ethernet access may be distributed over up to 4 IBM i iSCSI HBAs.
|
 |
| · |
System x models may have up to 4 iSCSI HBA ports.
|
 |
| · |
Blade systems have one dual-port iSCSI HBA.
|
 |
| · |
A BladeCenter as a whole may have up to 14 iSCSI HBAs (one dual-port iSCSI HBA per blade that is present).
|
 |
| · |
The maximum Ethernet cable length between a switch and an iSCSI HBA (IBM i target or BladeCenter/System x initiator) are:
100m for copper (category 5e or 6) cables
220m for 62.5/125 µm multimode fiber cables
500m for 50/125 µm multimode fiber cables
|
 |
Footnotes:
1 The actual number will depend on the amount of I/O that each blade or System x model is doing.

The minimum server firmware required for the #5783 PCI-X iSCSI HBA Copper and #5784 PCI-X iSCSI HBA Fiber adapters are:
- For Model 520 Power5+ (Processor Features 8325, 8327, and 8330) the server firmware level must be 240_219 or later.
- For all other supported models and other 520 processor features,
the server firmware level must be the later of either 235_185 or the specific FW level
required for your model/processor (which can be found at
http://www-912.ibm.com/e_dir/eServerPrereq.nsf).
