Hardware Requirements for IBM System p Models
One or more of the following processors is required by the lin_tape device driver:
v
IBM low, middle, or high range System p (also known as pSeries) servers
running a 64-bit Linux operating system
v
IBM POWER5
servers running a 64-bit Linux operating system
One or more of the following host bus adapters:
v
PCI-X DDR Dual -x4 SAS Adapter (FC 5900)
v
System p (also known as pSeries) Feature Code 5712 PCI-X Dual Channel
Ultra320 SCSI Adapter
v
System p (also known as pSeries) Feature Code 5736 (571A) or 1912 PCI-X DDR
Dual Channel Ultra320 SCSI Adapter
v
System p (also known as pSeries) Feature Code 6228 Fibre Channel Adapter
v
System p (also known as pSeries) Feature Code 6239 Fibre Channel PCI-X
Adapter
v
System p (also known as pSeries) Feature Code 5716 Fibre Channel PCI-X
Adapter
v
System p (also known as pSeries) Feature Code 5758 and 5759 Fibre Channel
PCI-X Adapter
v
System p (also known as pSeries) Feature Code 5773 and 5774 Fibre Channel
PCI-E Adapter
v
System p (also known as pSeries) Feature Code 5735 8 GB Fibre Channel
Adapter
Hardware Requirements for IBM System z Models
One or more of the following processors is required by the lin_tape device driver
running Linux on System z in 31-bit or 64-bit:
v
IBM System z 800 (z800) or 900 (z900) models
v
IBM System z 890 (z890) or 990 (z990) models
v
IBM System z9
®
models
One or more of the following host bus adapters with Fibre Channel Protocol
support:
v
FICON
®
Express card (feature 2315 or 2318)
v
FICON Express card (feature 2319 or 2320)
v
FICON Express2 card (feature 3319 or 3320)
v
FICON Express4 card (feature 3321, 3322, or 3324)
Note:
Using a single Fibre Channel host bus adapter (HBA) for concurrent tape
and disk operations is not recommended. Tape and disk devices require
incompatible HBA settings for reliable operation and optimal performance
characteristics. Under stress conditions (high I/O rates for tape, disk, or
both) where disk and tape subsystems share a common HBA, stability
problems have been observed. These issues are resolved by separating disk
and tape I/O streams onto separate HBAs and using SAN zoning to
minimize contention. IBM is focused on assuring server and storage
configuration interoperability. IBM strongly recommends that your
implementation plan includes provisions for separating disk and tape
workloads.
