LTO Media Reuse and Maximum Native Drive Speeds
Speeds shown are native rates. IBM i typically gets 3:1 compression on external tape drives, so the media will typically
hold 3* the amount shown and the drives may run at up to 3* the speed shown, unless they are bottlenecked by another
component in the path. Check the benchmarks in the Performance Capabilities Reference Manual for more information.

2008 July 22 announce
Note that a 520-M15 can only use smart (IOP-less) IOAs
since it can‟t attach extra towers, so tape options are:
• Integrated SAS drives shown on this page
• Smart SCSI IOA external drives – HH LTO2,
QIC SLR 60, QIC SLR 100, TS2230 HH LTO3
• Smart fibre IOA external drives
• Smart SAS IOA external drives
For other tape options, use a PCI card and attach an external tape drive
• IBM 7207-330 (QIC SLR 60)
• IBM 7212-103 (External Storage Device Enclosure) with
feature #1107 (QIC SLR 60) or feature #1108 (QIC SLR 100)
• Attach via SCSI smart IOA #5775 or via SCSI IOP-based IOA
Note: No QIC tape drive in the system unit bay - use an external QIC drive instead:

When reloading a system
using a drive attached to
a non-bootable IOP‟d
fibre adapter card, you
need to do an “alt-install”
by booting to your
Licensed Internal Code
(LIC) CD, then reviewing
the list of attached drives
and selecting the one that
has the *SAVSYS tape in
it.Not Bootable. Use Alt-install
When reloading a system,
drives on the LVD SCSI
and IOPless fibre/SAS
cards can boot directly to
the *SAVSYS tape if the
card is in an alt-IPL slot.
Fibre drives need to be
direct-attached or zoned
so they are the only drive
visible to the card

Without an IOP, CCIN 5736 is called fc 5775 on a 9406,
9407, 9408, 9409. On 9117, 9119, fc 5775 is not used.
Instead, for tape, we use fc 5736 for IOPless, and fc
5806 for IOP’d. For disk, we only use fc 5736 and
don’t differentiate IOP vs IOPless

IOP it is called fc 5736 on 9406, 9407, 9408, and fc 5806
on 9117 or 9119 systems.
• #2749 is the HVD SCSI card. On POWER6, it is only

To Estimate the Performance of a new drive:
• Figure out how fast the current drive is
running
• Match it to the benchmarks for the current
drive
• Read off the performance for the new
drive for that benchmark

Comparison: Tape Drive vs BRMS SW Based Encryption
Advantages
• Any type of tape drive
• Mix/Match encryption on 1 cartridge
Considerations
• Significant increase in CPU utilization
• Significant Performance Degradation
• May take up to 3* as much media
• Certain system libraries can‟t be
encrypted

• Encrypts whole cartridges
Advantages
• No impact on CPU utilization
• Max 1% performance degradation
• No increase in media required
• All objects can be encrypted

Tape Drive Based Encryption RemindersThings to Remember
Hardware Required– LTO4 or TS1120/TS1130 tape drives
– Fibre or SAS (not SCSI)
– Drives must reside in a tape library (although it‟s OK to run in
sequential mode)
– LTO4 media for LTO4 or any TS1120/TS1130 formatted media
– Comparable gear at your recovery site
Software Required– If the EKM will be run on Windows, SUN or HP, purchase the “TotalStorage Productivity
Center – Basic Edition” software to get the IBM Java Runtime Environment (IBM JRE)
Encryption Key Manager (EKM) reminders– Don‟t encrypt your EKM
– Have multiple EKMs at your home site and DR site
– Save your EKM and send a copy offsite anytime your keys change
Other Reminders– Choose TS3500 / 3494 over other libraries since it can turn encryption on/off based on volser
– Include ALMS on a TS3500 order so encrypted/non-encrypted drives can share a TS3500 partition
– Hire IBM Lab Services to help with install/setup (contact Mark Even in Rochester)

Data de-duplication (often called "intelligent compression") is a method of reducing storage
needs by eliminating redundant data. Only one unique instance of the data is actually
retained on storage media. Redundant data is replaced with a reference or pointer to the
unique data copy.
1. Data elements are
analyzed to determine a
unique signature for each
2. Signature values are
compared to identify all
duplicates
3. Duplicate data elements
are eliminated and are
replaced with pointers to the
existing reference element

IASPFlashCopy
ASP Quiesce Function with IBM i 6.1
Suspends transactions & operations to DB2 and IFS to help ensure that as much in-flight
data as possible is written to disk
– Intended for use with applications running commitment control
– Places transactions at database boundaries if possible
– Backup will still be seen as „abnormal‟ but much friendlier
Use with storage based copy technologies eg
– IASP FlashCopy operations
– IBM i XSM Geographical Mirroring Detach
Applications without commitment control might be OK, but assessment and testing is
required

No Special Procedures are required for BRMS
(iASP customers will typically use the Copy Services
Toolkit for automation of their environment)
For BRMS to work properly, do one of the following:
1) Follow the manual procedures at
http://www-03.ibm.com/servers/eserver/iseries/service/brms/flashCopy.html
*or*
2) Buy the BRMS FlashCopy Toolkit from Rochester Lab

SAN Design for IBM i
Firm Rules
• Multipath is not supported for Tape
• Maximum Addresses per Tape Fibre adapter
• Fc 2765, 5704, 5761 – 16 devices
• Fc 5749, 5774 – 64 devices * 2 ports
• 32 Drives per TAPMLBxx
• Disparate Drives must be separated via
• Separate tape adapter cards
*or*
• Separate tape library partitions
Best Practices
• Put Tape Adapters alone on an IOP
or virtual IOP so they can be reset
• Plan Ahead for alt-install
• Don‟t Mix Disk/Tape on a Fibre
adapter
• Design for Performance and
Resiliency
