The data center of the future
Application services
Application services
 Our reason for being
 The tools our clients use to do their jobs
 The ONLY thing our client cares about (in
terms of IT)
Application services (2)
 In the data center of the future,
application services are modules added,
deleted and modified completely
independently of the underlying
infrastructure
 Application services are assigned a
“business value” – which tells the
infrastructure the attributes necessary to
comply with that service’s SLA
Application services (3)
 The application services layer is
COMPLETELY abstracted (and virtualized)
from the infrastructure layers
 Applications interface to the physical via
APIs to call function – not to provide
function outside of their intended use. We
don’t even use volume manager anymore.
The data center of the future
Application services
Infrastructure services
Compute
services
Compute services
 A collection of processors – blades most
likely
 Interconnected through the network
services layer through both high- and lowspeed interconnects – IB and Ethernet (IP)
near term, who knows (or cares) long term
 The “grid” is capable of looking like
anything – a single machine that looks like a
lot of machines or a single machine
comprised of many “component” machines or any combination
Compute services (2)
 Blades are: a) Disposable, b) Hot pluggable,
and c) Never obsolete
 As long as they are operable, they are part of a
pool of compute resources used by the “grid
manager”
 The grid manager controls the inventory of
compute assets, assimilates virtual compute
instances for periods of time, dictated by SLA
requirements of the “application services
manager”
 The grid manager controls the liquidity of the
server farm – how the server farm presents
itself to the application services layer

Network services
Physical connectivity layer connecting
everything to everything
•
•
•
•
•
Multiple current and future technologies (IP,
IB, FC)
Multiple concurrent protocol support (FC,
SCSI, iSCSI, FICON, IB)
Smarts to know what’s what and why
Smarts to utilize, provision, and provide true
QoS (by individual application service)
Intelligence lives here
Network services (2)
Intelligence in the network
•
Smarts exist both here and at the data
services layer, with the heavy lifting
happening at the network layer
Network services (3)
The network will control:
•
•
•
•
•
•
•
Macro data placement (what goes on what, when)
Volume management (who sees what)
Data migration (routing)
Replication
Quality of Service to the application services layer
ILM/DLM policy execution
Backup/Recovery/DR

Network services will enable ILM
Do you believe that intelligent storage networks are necessary to
implement an effective Information Lifecycle M anagement solution?
Don't know, 11%
No, you do not need
intelligent storage
networks to have an
effective ILM
solution, 7%
Yes, you cannot
have an effective
ILM solution
without intelligent
storage networks,
40%
Somewhat,
intelligent storage
networks would
facilitate an effective
ILM solution but are
not necessary, 42%

Data services
 This is the physical storage layer, and the
associated resource management,
movement and protection
 This is where ILM/DLM is real, not fantasy
 Big issues:
•
•
•
•
•
Change management
Data valuation
Asset classification
SLAs by application class (not infrastructure
class)
Information security
Data services – Storage tiers
Tier 1: Enterprise disk (50TB)
Tier 2: FC disk (NAS and SAN) (50TB)
Tier 3: iSCSI/FC ATA/SATA/Other cheap disk (150TB)
Tier 4: Massive disk archive (1PB)
Tier 5: Deep archive tape & optical (multiple PBs)
All tiers tied together via multiple protocol,
super-intelligent switching platforms with
high-end QoS capabilities (network
services layer)
Common factors among tiers
 All tiers fault-tolerant
 All systems future proofed – never get
old - just get newly “tiered”
 Tiers may have overlapped components
 Access to each tier will include block,
file AND object
Tier 1
 High-performance (perhaps not the
highest)
 Super-scale in 3 dimensions (capacity,
I/O, throughput)
 Mainframe AND open connectivity
Tier 2
 High-performance (probably the
highest)
 Will need to present single system
image from small to huge – single box to
many
 Flexible capacity entry points
Tier 3
 Low-cost, idiot-proof, automatic add,
management “free” – self-actualizing
storage
 ISCSI mandatory
 Thousands of server connections
Tier 4
 Scale to multi-petabytes
 Massive density – super low acquisition
cost AND operating cost (power)
 Kills the big tape library market
Tier 5
 Deep archive tape & optical – smaller
libraries, bigger fatter cheaper media
 Performance is irrelevant (it almost is
already)
 50TB/cartridge plus
 Will have to have object indexing offload
right in the media – which will require
standards

Storage manager skill requirements
For the next 5 years:
Control the baseline
Build the tiered infrastructure
Connect everything to everything
Master physical management
Create classifications of
infrastructure/data services
 Create the cross-functional committee to
determine application service “values”
 Understand costs per class

Storage manager skill requirements (2)
After 5 years:
 All infrastructure/data services WILL be
automated – traditional storage
administrations services will have gone the
way of the dodo. Any manual labor job is
no longer in existence. There are no more
tape guys. There are no more “sys admins”
either. The box is smarter at the mundane
than the human.
Storage manager skill requirements (3)
After 5 years:
 The “Data Services Manager” (DSM) will be
responsible for adding/removing/changing
and integrating new technologies into the
Liquid Infrastructure
 The DSM will “monitor” SLAs, given to the
application services layer – and make
changes as needed. The DSM spends
his/her time on creating and implementing
POLICY changes.
Storage manager skill requirements (4)
After 5 years: The upside
 The upside for the DSM is the network
services layer. The critical smarts WILL
execute in the network – so the DSM who
speaks the networking language is in the
driver’s seat – and owns ALL of the strategic
responsibilities of the infrastructure – which
is much more valuable than owning the
tactical responsibilities.
 THE LESSON: Get your networking act
together. Now.
This has been done before!
