ProtecTIER Demo Sign on and look around

Repeat for 2nd ProtecTIER node

Notice the ProtecTIER is idle right now
Notice the entire repository is available right now. Nothing has been saved yet Take a look at the Source ProtecTIER

Repeat for the Target ProtecTIER

Look at the Comms Config
ProtecTIER Demo Look at the Comms Config

(3) Review on remote ProtecTIER too if you want
xx (1) These are the fibre ports that connect the IBM i servers to the ProtecTIER. The fibre ports that connect the disk repository are not displayed via the PT GUI. A dual-node ProtecTIER would have 8 ports (3) Review on remote ProtecTIER too if you want (2) These are Ethernet Links for the ProtecTIER HA Cluster (if you have a 2-node system) and IP Replication (if you have it)

Create a VTL / Drive / Media
ProtecTIER Demo Create a VTL / Drive / Media

Create VTL / Drives / Virtual Media
This defines the library Note that this name does not get passed to the IBM i. You should sign on later and rename the TAPMLBxx to this name to make your life simpler Always choose IBM TS3500 for IBM i

These screens plus the next one defines the 4 drives

Design your drive attachment configuration carefully before filling out this screen You would normally spread the drives across all ports (but our system only has 1 fibre cable!)

This screen creates your virtual media. If you consume all your repository space with scratch cartridges, the size of unused cartridges will vary over time as your de-dup ratio varies. Instead, set the max cartridge size and create enough scratch tapes to get to your “Steady State”, then make more scratch cartridges later In choosing the cartridge size, remember that an IBM i Tape library can have at most 5000 “elements” (places where cartridges are stored) and every virtual cartridge needs a slot

Define the slots and convenience IO for your library Don’t skimp on the slots since you have to take the PT offline to add more. You need more slots on a virtual library than a physical library since all tapes need a slot. On physical libraries, many of the active tapes are not in the library because they are offsite Beware that IBM i has a max of 5000 “elements” in a tape library. An element is anywhere a tape can reside – slots, drives, picker, and convenience io Make enough convenience I/O slots to hold all the tapes you want to eject each day

VTL Creation Confirmation Screen

Wait while the library is created, then sign on to the IBM i and reset the tape adapter so the virtual library will auto-configure Switch to the Remote ProtecTIER and create TGTVTL2 the same way

Check the VTL / Drive on the IBM i
ProtecTIER Demo Check the VTL / Drive on the IBM i

xx (4) Run INZBRM *DEVICE to update BRMS
(1) Use STRSST to reset the tape adapter attached to the ProtecTIER so it will report in. (3) Mark the drives “unprotected” (2) The ProtecTIER will take the next available TAPMLBxx name. Rename it to match the name you keyed on the PT GUI to keep your environment orderly

Check the VTL / Drive /Media on the ProtecTIER
ProtecTIER Demo Check the VTL / Drive /Media on the ProtecTIER

xx 1) Pick the proper system/node 2) Pick the VTL of interest
3) Move through the tabs to see all the details of the VTL

xx Look at the drives

xx Look at the virtual volumes

xx Look at the media sorted by slot #

xx Look at the Convenience IO Station

Set up BRMS ready to do a save
ProtecTIER Demo Set up BRMS ready to do a save

Note that you can make the cartridges any size you like, not just LTO3 sizes. Performance will match whatever your ProtecTIER configuration allows – you’re not tied to LTO3 speeds. xx Make a BRMS Media Class. Remember the TS7650 emulates LTO3. If you also have regular LTO3 drives, you need separate media classes for physical vs virtual LTO3 volumes.

Repeat this for any volumes on the remote ProtecTIER
INZBRM *DEVICE first xx Repeat this for any volumes on the remote ProtecTIER Add the virtual volumes into BRMS using ADDMLMBRM. Be sure to initialize them or they will get an odd label that will cause trouble later. You may want to use the actual command vs getting there from WRKMLMBRM

If desired, make a BRMS Move policy that moves the tapes to the remote VTL and back again. Choose if you want to verify moves or not (either will work with ProtecTIER IP Replication)

Make a BRMS Media Policy that points to the Virtual LTO3 media class and your new move policy

Make a BRMS Control Group to do your save
Make a BRMS Control Group to do your save. Make sure it points to the new Media Policy you just made and the virtual library Before we run the BRMS Control group, let’s also set up a replication policy on the ProtecTIER

ProtecTIER Demo (aside) What’s the Shelf?

Replication Concepts – High Level
Local ProtecTIER Remote ProtecTIER Replication is done by Volser Replication Policy #1 A01 A02 A03 A01 A02 A03 If a volser is not listed in a replication policy, it doesn’t replicate B01 B02 B03 Replication Policy #2 C01 C02 C03 C01 C02 C03 Different Replication Policies can be used for different volser ranges – eg different systems or backups or priorities BUT … duplicate volsers are a problem for backup applications … so ProtecTIER has an elegant solution using “Visibility Switching” via “The Shelf” …..

Replication Concepts – Visibility Switching and “The Shelf”
Local ProtecTIER Remote ProtecTIER Each ProtecTIER has a “shelf” where the non-active copies of the tape are stored After Replication, if the tapes are more likely to be used at the primary site, then leave the remote copies on the remote shelf A01 A02 A03 B01 B02 B03 If the tapes are more likely to be used at the remote site, then ProtecTIER can work with the backup application to move them into the remote library automatically Replication Policy #1 C01 C02 C03 Replication Policy #2 Local Shelf Remote Shelf A01 A02 A03 Tapes can also be moved manually. It’s also possible (but unusual) to keep both copies on their respective shelf, or both in their respective library C01 C02 C03

ProtecTIER Replication – Replication Queue
SRC-VTL1 TGT-VTL2 001 Replication Queue 001 001 SRC-SHELF TGT-SHELF Tapes always replicate from a Virtual VTL to a shelf For replicated tapes, the data is kept on BOTH systems, but is only accessible to the tape management system from 1 site at a time A replication policy that has a VTL as a target lets the Tape Management System move the replicated tape into the remote VTL Depending on your replication policy, tapes can start replicating the minute a byte of data hits the virtual volume, or they can wait till the timeframe you set as your replication window. Note that you need to allow bandwidth for replication.

Initially, our shelf is empty
xx Initially, our shelf is empty

Set up the System-wide Replication timeframe
ProtecTIER Demo Set up the System-wide Replication timeframe

Check the System Wide Replication Timeframes
Ongoing Replication is easiest for testing, so click the top radio button for our demo Replication throttles are available for both physical and nominal transmissions Be sure to size the repository for enough bandwidth if you plan to run both saves and replication at once

Set up a Replication Policy
ProtecTIER Demo Set up a Replication Policy

(2) Click on Replication to create a new policy
(1) There are 2 replication policies here already from someone else. They handle different tape volsers from the ones we are using.

Creating a Replication Policy

Our first Replication Policy will leave the tapes on the Shelf at the Remote Site (vols SRC001 to SRC002) Thereafter, we’ll repeat the steps to make a 2nd Replication Policy that moves the tapes into the Remote VTL (vols SRC003 to SRC005). These tapes would normally HAVE a BRMS Move policy Normally, tapes in a “shelf” replication policy would use a BRMS save that did NOT have a move policy (but we accidentally gave them a BRMS move policy in this demo!)

When we repeat the steps to make a 2nd Replication Policy that moves the tapes into the Remote VTL, we’ll assign it to vols SRC003 to SRC005

Confirmation Screen for first Replication Policy

Here’s how it will look once the 2 new replication policies are created
Highlight each policy on the pane above to look at the details on the right

Watching the Backups Run
ProtecTIER Demo Watching the Backups Run

Kick off the first BRMS Backup, then look on the ProtecTIER.
Virtual Volume SRC001 is mounted on virtual drive #3

Go to the Cartridge Tab and you can see virtual volume SRC001 filling.
xx Go to the Cartridge Tab and you can see virtual volume SRC001 filling.

xx Go to the System Screen and see the activity on the ProtecTIER fibre ports. DD3 ProtecTIER ports were 4 Gbit, DD4 ports are 8 Gbit. Remember your SAN needs to be 8 Gbit to take advantage of the DD4 ports

Eventually as you run a few backups, you can see some stats on dedup ratios

The remote ProtecTIER has similar stats for the replicated data

Watching the Replication Run
ProtecTIER Demo Watching the Replication Run

On the local ProtecTIER, you can see the replication activity pending
xx On the local ProtecTIER, you can see the replication activity pending

xx On the local ProtecTIER, now you can see the replication activity running

xx Go to the remote ProtecTIER and notice our virtual volume, SRC001, is now on the shelf there, filling gradually since we told it to start replicating as soon as there was data on the tape vs waiting for a replication window

xx Run another BRMS save and SRC002 will also replicate to the remote shelf Oops! SRC001 and SRC002 have a “shelf” replication policy, so we should have done a BRMS save with no move policy.

ProtecTIER Demo Manual Move from Shelf

Manually Moving a Replicated Tape
Suppose you needed to restore some data from a tape that was on the remote shelf, eg SRC001. You can move it into the library manually and do your restore. Plan to move it back to the shelf again when done.

ProtecTIER Demo MOVMEDBRM

Now kick off 2 more backups so SRC003 and SRC004 will get some data.
xx Now kick off 2 more backups so SRC003 and SRC004 will get some data. They have a different replication policy that will send them into the remote VTL eventually via the BRMS MOVMEDBRM process

xx Now we have 4 tapes in the local VTL with data on them (plus 1 scratch) In the background, they have also replicated to the remote VTL SRC001 / SRC002 have the shelf as their replication destination SRC003 / SRC004 have the VTL as their replication destination

xx Initially, the 4 tapes we have written on are all inside the local virtual library

xx Now run MOVMEDBRM. BRMS will move all the tapes out of the local library and onto the local shelf. In real life, you likely wouldn’t have assigned a BRMS move policy to the tapes that have a “Shelf” Replication Policy (SRC001 and SRC002) since you’d like your primary copy to stay available in the local library

All 4 tapes disappear from the local virtual library
All 4 tapes disappear from the local virtual library. Just the one remaining scratch tape (SRC005) is still there.

Now sign on to the remote IBM i and look at the remote Virtual Library
Now sign on to the remote IBM i and look at the remote Virtual Library. Like magic, a copy of SRC003 and SRC004 are now in that library. Notice that SRC001 and SRC002 didn’t move into the library since they have a Shelf replication policy

Run ADDMLMBRM to make the tapes available in the library, just like you would do if physical tapes had arrived back and you wanted to put them into the physical library.

Our two replicated tapes are now in the remote library, ready to use for restores or duplication to physical volumes. Notice that the two scratch tapes we made at the remote site are there too in case we need to failover and start running saves at that site

On the ProtecTIER, you can see the two replicated tapes in the remote library too. Notice that they are marked “read only”

The tapes will move back to the primary site the first time MOVMEDBRM runs after they expire
BRMS knows the proper location of SRC004 and SRC005. SRC001 and SRC002 are mixed up because we accidentally gave them a move policy

Tadaa! Now you’re an expert On the ProtecTIER GUI!

Notes on Performance Estimates
rPerf for AIX rPerf (Relative Performance) is an estimate of commercial processing performance relative to other IBM UNIX systems. It is derived from an IBM analytical model which uses characteristics from IBM internal workloads, TPC and SPEC benchmarks. The rPerf model is not intended to represent any specific public benchmark results and should not be reasonably used in that way. The model simulates some of the system operations such as CPU, cache and memory. However, the model does not simulate disk or network I/O operations. rPerf estimates are calculated based on systems with the latest levels of AIX and other pertinent software at the time of system announcement. Actual performance will vary based on application and configuration specifics. The IBM eServer pSeries 640 is the baseline reference system and has a value of Although rPerf may be used to approximate relative IBM UNIX commercial processing performance, actual system performance may vary and is dependent upon many factors including system hardware configuration and software design and configuration. Note that the rPerf methodology used for the POWER6 systems is identical to that used for the POWER5 systems. Variations in incremental system performance may be observed in commercial workloads due to changes in the underlying system architecture. All performance estimates are provided "AS IS" and no warranties or guarantees are expressed or implied by IBM. Buyers should consult other sources of information, including system benchmarks, and application sizing guides to evaluate the performance of a system they are considering buying. For additional information about rPerf, contact your local IBM office or IBM authorized reseller. =============================================================== CPW for IBM i Commercial Processing Workload (CPW) is a relative measure of performance of processors running the IBM i operating system. Performance in customer environments may vary. The value is based on maximum configurations. More performance information is available in the Performance Capabilities Reference at: Revised April 2, 2007
