The data center of the future
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
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.

Application services
Compute services
Compute services A collection of processors – blades most
likely
Interconnected through the network services layer through both high- and low-speed 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
• Security management

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

Data services
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!This has been done before!
