IT consolidation: file servers with networked storage migration solutions 3
overview of HP IT consolidation strategy
HP recognizes that a desire to reduce cost begins the drive for most consolidation projects. HP helps its customers identify the areas where consolidation will provide the greatest return. HP consolidation strategy goes one step further by addressing infrastructure complexities through achieving “the vision of a utility-driven computing
environment.” In this environment, the focus is expanded beyond managing services to a provisional on-demand service fulfillment that drives greater business value. The HP Utility Data Center (UDC) solution and HP Adaptive Enterprise strategy provide the general concept for the HP IT consolidation strategy. General industry analysts’ research has shown the IT consolidation market to be an installed-base initiative with organizations favoring current vendors. With the HP product depth and breadth of high-end computing to HP standard Intel architecture server (SIAS) install base, HP’s IT consolidation strategy is well positioned to deliver manageable, scalable, reliable, and secure consolidated IT environments.
IT Economics for IT Consolidation=Driving down costs while improving service quality + managing risks to create greater agility for your business.

industry analyst view on consolidation
The widely distributed IDC categorical definition of consolidation was developed
through interviews of IT managers selected at random across the U.S. and is comprised
of the following five parts:
? Centralization – Collocation of servers and/or storage systems into fewer locations or
one central location
? Physical – Consolidation of servers or storage systems with the same application
types or platforms onto fewer or larger systems with the same application type or
? Data integration – Combining data with different formats onto a similar format or
? Application – Consolidating servers or storage systems supporting different types of
workloads onto fewer or larger systems
? Storage – Consolidating storage onto fewer or larger storage systems independent
of server type, operating systems, or application.
Moreover, HP aligns its consolidation offerings around the major consolidation
categories with a services approach. The services approach begins with a value-
assessment workshop to a total investment justification for a consolidation project with
measurable objectives. The model below illustrates the consolidation entry points
across multiple parts of an infrastructure.

the HP IT consolidation journey
overview of infrastructure consolidation
Components of the HP infrastructure consolidation offerings encompass the following categories:
? File & Print
? Messaging & Collaboration
These major infrastructure categories are a must in active and future installed-base environments and represent a core share of HP server deployments.

file & print
File server and Print server consolidation is traditionally driven by creating a homogenous operating system (OS) platform and grouping the remote file shares down to a multiprocessor server. The key for File & Print consolidation is having the similar OS across your File & Print consolidation deployment. According to industry surveys, Microsoft and Linux are the most widely “migrated to” consolidated OS platforms, with
Linux on ProLiant servers leading the non-Microsoft migrated-to environment, based on the total cost of ownership (TCO). File & Print consolidation efforts fall in the Centralization, Physical, and Storage categories according to IDC, April 2002, Server and Storage Consolidation: Executive Interview Summary Report.
Messaging & Collaboration
Messaging & Collaboration consolidation is driven by creating homogeny around the application. The key for Messaging & Collaboration consolidation is to drive down the number of similar application servers but to not lose any computing power in the process. Applications such as Exchange/NT, Domino/Solaris 8, and Domino/AIX represent the Messaging & Collaboration system enterprises that are consolidating due to merger and acquisitions or previously stated business cases.

Networked Attached Storage (NAS) and Storage Area Network (SAN) migration considerations
key differentiators of NAS and SAN
Misinterpretations of Networked Attached Storage (NAS) and Storage Area Network (SAN) differences create some confusion in understanding the business value beyond having a networked storage environment. By deployment definition, NAS solutions are for file serving and SAN solutions provide data block management. The image in the top right corner depicts an HP StorageWorks MSA1000 SAN machine. Considered an excellent entry product for customers consolidating Direct Attached Storage (DAS) environments to a SAN, it is an ideal product for NAS/SAN mixed environments. For more information on the MSA1000 and other storage products, please go to http://www.hp.com/country/us/eng/prodserv/storage.html
NAS and SAN convergence operational benefits:
? Consolidation of file servers
? Non-disruptive system upgrades
? Improved data availability
? Low management costs
? Foundation for future storage requirements file & print consolidation utilizing department-level NAS A NAS system provides ideal support for department-level deployments. Sizing considerations for a typical NAS system supporting a department of 50 to 250 people should be the general working parameters. Workload management and file share management tools are a must for any file server or print server consolidation effort. NAS operational benefits:
? Multi-platform file sharing
? Fast and easy installation
? Low management costs file & print consolidation utilizing enterprise-level SAN Reiterating the deployment definition of SAN for data block management, the file & print services would serve better as part of a NAS system as described previously. However, utilizing a SAN for file server or print server purposes would require additional cost/benefit analysis by the organization since the SAN solutions are normally more expensive to implement compared to a NAS solution. The host of software tools for data management and support which are required for a SAN deployment would offer ample capability of file serving.
SAN operational benefits:

? Storage consolidation
? Better backup and recovery
? Higher availability
? Fast scalability
? Proprietary data sharing consolidation solution scenarios
An IT department wants to streamline its print server farm and people in the corporate office are investigating ways to decrease the marketing communications materials and general forms. This cost applies to the headquarters and satellite offices who often defer to local print service providers (PSP) for order fulfillment.
A print-on-demand server for the departmental workforce and forms/collateral driven business function whether they serve corporate and/or satellite locations. This solution provides a just-in-time fulfillment of print request while optimizing IT support by consolidating and standardizing a print-on-demand repository. Local PSPs can be leveraged as an outsourced function for mid to high end jobs while delegating business function print orders through a central print repository. PSPs can utilize this solution as an extended service to customers/clients.
virtual IP-based file cluster
IT departments across enterprise are looking for creative ways to maximize availability of corporate business unit file servers.
Virtual IP based file server clustering HP ProLiant servers supporting business unit workforce levels of 300 to 1200 users. This IT consolidation aspect provides organizations optimal availability of their file share allowing IT administrators’ greater flexibility for support and upgrade procedures. As corporate desktops continue to take on more of a centralized thin client-like architecture, availability of business unit file access will continue to stimulate this trend.

vertical architecture (scaling up)
Enterprises recognize tremendous front-end web and application server growth that resulted in a highly scaled out environment. As a result, enterprise server farm management, along with decentralized “same job, different boxes” for backend support, has become an albatross.
Scaling up involves moving applications to a “bigger,” more capable server such as ProLiant ML530, ML570, DL580, or DL760. The symmetric multiprocessing (SMP) systems, which require specialized hardware and software, stand at the high end of these “bigger” servers. Scale up best practices for backend servers culminated out of extensive lab and field tests. Virtualizing OS instances on SMP systems maximize machine usability. HP partners, such as VMware, provide technology that achieves partitioning within 4- and 8-way servers
