Iterative /
modest amount of SSD capacity

First query draws data from HDD “relatively slow”, question
but data then cached on SSD. Second, third,
fourth, etc query MUCH faster !!!! 1
2
When query work of this data ceases, SSD space 3
reused for new queries. 4
Questions/analysis are usually iterative. The first
question generates additional drill-down or expanded
questions. The raw data for the first question gets
reused a lot until the topic exploration is completed.
Example – “what am i selling?” “what am i selling in
the evening?” “what am i selling in the evening by
store?” etc, etc

- 10. SSD Client Example – IPL Reduction
IBM Development has projected Less downtime
modest improvement for IBM i and
for AIX, but …..
IBM i POWER6 520 client with 16
drives (4 SSD and 12 HDD)
Client put load source on SSD
Now reporting 3 minute IPLs
POWER7 IBM i client also reporting 3
minute IPLs
Much faster PTF applications
What is your cost per minute or cost per hour for down
time? How long is your typical IPL?
19 Power is performance redefined ©2012 IBM Corporation
Many Systems Buy “Extra” Disk Arms for Performance
HDD % utilization of capacity is held low to help ensure higher I/O performance
and more consistent response time - arm movement, spinning platter an issue
Write cache and read cache attempt to buffer the impact
Often less than 30-50% full for performance sensitive workloads
SSD % utilization of capacity not restricted
Can run much closer to 100% full
20 Power is performance redefined ©2012 IBM Corporation
- 11. Mixed SSD + HDD Can be Great Solution
It is typical for data bases to have a large percentage of data which is infrequently
used (“cold”) and a small percentage of data which is frequently used (“hot”)
Hot data may be only 10-20% capacity, but represent 80-90% activity
SSD offers best price performance when focused on “hot” data
HDD offers best storage cost, so focus it on “cold” data …. a hierarchical approach
Cold May be able to use larger HDD and/or a larger % capacity used
Hot Can run SSD closer
to 100% capacity

Should You Use SAN/SVC SSD or Internal SSD?
Pro’s Con’s
Use
Internal yes yes
SSD
Use
SAN/SVC yes yes
SSD
“Internal” = drives located in a system unit, in an I/O drawer with PCI slots or in a disk-only I/O drawer.
24 Power is performance redefined ©2012 IBM Corporation
- 13. DAS & SAN - Two Good Options
Both options are strategic
Both options have their strengths
Can use both options on the same
server

Direct Attached Storage Storage Area Network
(“internal”) (“external”)
• Fastest (lower • Fast
latency) • Multi-server sharing
• Typically lower cost • Advanced functions/values
Flash Copy, Metro/Global
hardware/software
Mirror, Live Partition Mobility,
• Often simpler config Easy Tier
25 Power is performance redefined ©2012 IBM Corporation
SSD - SAN/SVC or Internal …. Or Mixed?
Pro’s Con’s
1. Lower latency - internal is about 1. If already have SAN/SVC, adds
0.3 milliseconds faster (per access complexity of having internal
Use .. it can add up) (can be larger) PLUS SAN/SVC
2. If don’t already have SAN/SVC,
Internal lower cost & less learning
2. Reduces value of SAN/SVC high
function capabilities – Flash
SSD 3. Multiple Config options Copy, MetroMirror, HA, partition
4. Handle just like other internal mobility, etc
storage
1. Leverage SAN/SVC well-known 1. If don’t have SAN/SVC, need
value proposition of initial SAN/SVC investment in
Use manageability, control, hardware, software, skills
functionality, performance, etc 2. Many medium/entry SAN/SVC
SAN/SVC 2. If already have SAN/SVC, less don’t offer SSD
SSD learning, reduced cost to add
3. DS8000 & V7000 EasyTier
MIXED: If using a SAN/SVC which doesn’t have SSD, OR if not using the higher
function capability of a SAN/SVC (for example you do backup/restore functions just like
it was an internal drive); THEN combining internal Power Systems SSD with SAN/SVC
storage can be a good thing.
“Internal” = drives located in a system unit, in an I/O drawer with PCI slots or in a disk-only I/O drawer.

- 14. SSD Technology “Myth”
“Beware SSD as they wear out as they have a limited number of
writes”
Key facts to correct myth …. this is not a concern for IBM Power
Systems SSD
IBM Power Systems SSD are industrial/enterprise drives designed to
handle this. Design points are many years of 24x7x365 heavy write
workloads. These are not “PC-grade” or “consumer-grade” flash drives.
Even if you do somehow “use up all the writes”, the SSD reports status prior
to it being a real problem to the server and server sends a message to the
operator or to IBM for a future scheduled repair action. This is just like a
disk drive reporting a weakening status. Replacement SSD is covered
under IBM Maintenance.
Just like disk drives, you want to protect contents using system mirroring or
RAID protection

- 19. Other Performance Insights – background reading
• Time to Write on a HDD is the same as time to read on an HDD (1:1 ratio)
• Time to Write on an SSD is much longer than a read on an SSD around (3:1 ratio)
• Thus the biggest SSD performance boost is for reads compared to HDD.
SSDs do reads at < 1 ms while from HDD are typically around 3-15 ms
• Writes to SSD are faster than writes to HDD …. BUT …. Write cache on a SAS controller is even faster than
a write to SSD. SSD can empty out the write cache faster than HDD, so SSD+write cache is generally faster
than HDD+write cache, but comparisons have more “it depends” caveats
• The size of information being handled makes a difference. Handling bigger blocks of data takes longer,
especially if doing writes.
• Randomness of information also plays a part. If there are a lot of smaller blocks of information which happen
to be close together where they will be eventually be stored, then they are more likely to be in the same page
of space in the SSD device’s internal controller. Thus the access and/or writes can happen “above” the real
flash memory and is faster.
• HDD have had ongoing cost/GB improvements over the last 5-10years, but have had little access
performance enhancements. Most performance boosts have been through enhancements in controllers of
HDD, not the spinning platter or arm. No significant HDD performance improvements are currently foreseen.
Thus the gap between server memory and HDD will continue to widen.
• If operating system can predict the data needed, it can issue a read prior to the application making the request
reducing HDD delay to application. But random reads by definition are not feasible to pre-fetch. Applications
with lots of random reads are thus THE ideal area for SSD benefits.
• Alternatives to SSD – 1) Can “pin” information in memory. This is even faster than SSD. But SSD can
provide a lot more GB of capacity and is usually more cost effective per GB. 2) Also could go buy a lot more
adapters with write cache and/or spread data out, but this is less cost effective than SSD.
• If an HDD fails, it can take hours to format and bring the new HDD into sync with either its mirrored pair or with
the rest of the RAID-5 array. The larger the drive’s capacity, the longer the resync time can be. Until re-
synced there is risk a second failure could crash the partition or application. If an SSD is replaced, the time to
resync so that the RAID array or mirroring protection is restored is MUCH, MUCH faster (minutes vs hours)
with SSD than HDD.
• For absolute best performance use internal SSD vs SAN SSD. There in about 0.3ms (3/10ths milliseconds)
additional latency in accessing SAN. For I/O intensive applications this adds up. But SANs can offer a lot of
other operational and managerial advantages for many clients. The performance trade off may be a good
thing to do in the overall decision.
• For VERY rough rules of thumb for mixing HDD & SSD – use about 5-15% of the GB of the data – or use
about 5-10% of the drives.
