The project was performed on behalf of MPhasis Ltd (a Hewlett Packard Subsidiary). The project required understanding the client's existing data center infrastructure, analyzing the client's current and future needs and suggesting a low cost, optimized solution with 60% virtualization.

3. Related Terms
SAN:-A storage area network (SAN) is an architecture to attach remote
computer data storage devices (such as disk arrays, tape libraries) to servers so
the devices appear as locally attached to the operating system.
VTL:-A virtual tape library (VTL) is a data storage virtualization technology
used typically for backup and recovery purposes. A VTL presents a storage
component (usually hard disk storage) as tape libraries or tape drives for use
with existing backup software.
Blade Server:- A blade server is a stripped down server computer with a
modular design optimized to minimize the use of physical space and energy. A
blade enclosure, which can hold multiple blade servers, provides services such
as power, cooling, networking, various interconnects and management.
Together, blades and the blade enclosure form the blade system.

4. Related Terms(continued)
Rack-mount server:-A 19-inch rack is a standardized
frame or enclosure for mounting multiple equipment
modules. Each module has a front panel that is 19 inches
(482.6 mm) wide, including edges or ears that protrude
on each side which allow the module to be fastened to
the rack frame with screws.
Rack unit:-A rack unit or U (less commonly RU) is a
unit of measure used to describe the height of equipment
intended for mounting in a 19-inch rack or a 23-inch
rack. One rack unit is 1.75 inches

5. What is Data Center and Data
Center Optimization?
A Data Center is a facility used to house computer systems and associated
components, such as telecommunications and storage systems. It generally
includes redundant or backup power supplies, redundant data communications
connections, environmental controls (e.g., air conditioning, fire suppression)
and security devices
Data Center Optimization is a journey from current to the aspired state
and it covers lots of small, medium and large initiatives to achieve the goal.

Most of the servers are not
connected to SAN

All are old physical servers with
space and compute power crunch.

The existing landscape can not cater
to business growth.

AMC costs are going higher.

Most of the hardware is out of end
of sales and end of warranty.

Growing power, cooling and
systems admin costs.

state to proposed state.

11. Data center facility consolidation

Data Center Consolidation involves the following steps
which are explained in the slides ahead:

12. Virtualisation
A method of partitioning one physical server computer into multiple
“virtual” servers, giving each the appearance and capabilities of running
on its own dedicated machine.
Each virtual server functions as a full-fledged server and can be
independently rebooted.
There are three areas of IT where virtualization is making head roads,
network virtualization, storage virtualization and server virtualization.

13. Storage Virtualisation
Storage Virtualisation refers to the abstraction (separation) of logical
storage from physical storage so that it may be accessed without regard to
physical storage or heterogeneous structure.
This separation allows the Systems Admin increased flexibility in how
they manage storage for end users.
The virtualization system presents to the user a logical space for data
storage and itself handles the process of mapping it to the actual physical
location.
 Storage virtualization is commonly used in storage area networks
(SANs)

14. Data migration
Data Migration is the process of transferring data between storage
types, formats, or computer systems.
Data migration is usually performed programmatically to achieve an
automated migration, freeing up human resources from tedious tasks. It is
required when organizations or individuals change computer systems or
upgrade to new systems.
To achieve an effective data migration procedure, data on the old system is
mapped to the new system providing a design for data extraction and data
loading.
Data Extraction where data is read from the old system.
Data Loading where data is written to the new system

15. Backup consolidation
Backup consolidation enables an organization to significantly reduce
application backup and restore times.
Today's backup technology uses high capacity tape drives this could be the
high capacity inexpensive disks, it automates backup, reduces sysadmin
effort for backup (virtual tape library), with point in time technology
Tie these solutions to a robust business continuity and availability
strategy-and the entire organization can benefit as :
oImprove backup reliability
oReduce media purchases
oSpeed backups and restores
oEnhance user productivity
oLower IT costs and increase operational efficiency
oEnable more effective decision-making that sharpens your competitive
advantage

16. Network consolidation
The virtualization layer guarantees that each virtual machine is isolated from
other virtual machines.
Virtual machines can talk to each other only via networking mechanisms similar
to those used to connect separate physical machines.
Isolation allows administrators to build internal firewalls or other network
isolation environments, allowing some virtual machines to connect to the outside
while others connect only via virtual networks through other virtual machines.

17. Methodology

18. Plan phase
In the plan phase the analysis of the following aspects is done :-
Current hardware
Current usage in terms of hardware and software
Various applications along with their hardware requirements
Flexibility and rigidity of software support
Rate of expansion and future usage
Licensing cost of various softwares and operating systems
 Risk factors like environmental changes, government policies etc.
 All this is done by queries response, face to face interviews, strategy
of migration, critical servers, is their any pending penalty on the client

19. Design phase
In the design phase a hardware and services support solution is created as per the
client requirement and keeping in mind the conditions pre-defined by the client.
This is a lengthy process which involves taking suggestions, feedback and
affirmation from multiple service support executives.
 An optimum design which suits all involved parties is the result.
 We identify the resources, project planning and duration, inter dependencies,
dependencies,issues,assumptions, risks(diar)
All stake holders are defines, meeting schedules, reporting formats are discussed,
implementation tools and technologies involved, associated downtime and
associated time-line is decided
Creation of BOM(Bill of Material) and detailed level scope of work
Customer go ahead is requested
Sign off is given

20. Implementation phase
After the design has been given a go-
ahead the service engineers perform
the following implementation
phases :-
Data center facility consolidation
Data migration
Backup creation
Network consolidation
Creation of VMs
 Building up SANs
Setting up
Data center site selection
DC build
Renovation of existing facility
 Placing order
 Putting infrastructure in place
 Network storage
 Securities
 Firewalls
Putting resources like sysadmin, sys
suport, on going support etc
Proof of concept
Sign off from customer
Documentation is handed over to on
going support
