PaperSave® Enterprise
Deployment White-Paper
Page 2
Introduction:
PaperSave® provides a complete and secure electronic storage system that seamlessly integrates into supported host information systems by attaching source documents relating to transactions or records within those systems directly to those records. Once documents have been associated with a given record, PaperSave® allows for the instantaneous on-screen access to those documents. As a result any source document retained through PaperSave® can be found instantly within the security confines of the host information system simply by navigating to the related record.
PaperSave® was designed with scalability in mind. It is a multi-tiered system that can consist of multiple application servers, multiple batch scanning servers, and multiple data servers. PaperSave® also uses one of the most highly scaleable database engines on the market (Microsoft SQL Server), to host the database. All of these components can be installed in any combination on one or many machines. Please refer to the diagram in the PaperSave® components interaction diagram section of this document.
As a result, a successful PaperSave® implementation requires a design that effectively uses the right combination of PaperSave® components and physical hardware resources to most efficiently handle and fit within the customer's process/volume and environment. It is recommended that a PaperSave® consultant from Solutions@MBA be involved in the design of any Enterprise implementation. PaperSave® consultants can provide the proper guidance and expert advice on the PaperSave® configuration and hardware required to meet a prospect's needs.
The primary purpose of this whitepaper is to provide PaperSave® enterprise customers/prospects and or their consultants with the proper guidance during the design of the environmental requirements
necessary to support a successful PaperSave® implementation. This white paper is broken up into two sections. The first section (PaperSave® Enterprise Recommended Deployment Guidelines) describes
scenarios/requirements that enterprise organizations are likely to encounter/have when
maintaining/planning their PaperSave® implementation, and the specific guidelines that govern those scenarios. The second section provides detailed hardware requirements for the machines and peripherals required to host/support PaperSave® components/features. Please note that multiple PaperSave®
components can be installed on the same computer as long as the computer meets the recommended requirements outlined for the most resource intensive component installed on that computer. Exceptions to this rule are specifically outlined in the PaperSave® Enterprise Recommended Deployment Guidelines section of this document.

PaperSave® Enterprise Recommended Deployment Guidelines:
The following table outlines how PaperSave® should be used under certain common Enterprisescenarios/customer requirements.
Enterprise Customer
Requirement Scenarios PaperSave® Deployment Recommendations by relevant component.
Database Server: Customer needs to store a
large volume (1 Million+) of PaperSave documents, or the documents stored within PaperSave have an average size of over 10MB+.
The customer will need either a dedicated machine for the PaperSave® database server component or a dedicated IO system for the PaperSave® database. A dedicated server will ensure that there is no contention for any database server resources between the PaperSave® database & the host system's database. As an alternative, customers can use a Shared SQL Server as long as the PaperSave database is hosted on a dedicated IO controller. This will ensure that there is no IO contention between the host system's database and the PaperSave database.
Database Server: The customer requires high
concurrent usage of the PaperSave® database for both adding and retrieving
PaperSave® documents. This would be defined as the concurrent (not serial) retrieval or submission of 20+ documents at any given time.
The customer will need either a dedicated machine for the PaperSave® database server component or a dedicated IO system for the PaperSave® database. A dedicated server will ensure that there is no contention for any database server resources between the PaperSave® database & the host system's database. As an alternative, customers can use a Shared SQL Server as long as the PaperSave database is hosted on a dedicated IO controller. This will ensure that there is no IO contention between the host system's database and the PaperSave database.
Database Server:
The customer will need a machine to host the PaperSave® database server component that is installed in a central location that is in the same physical LAN as the machine on which the Data Server is installed. Basically, there must be a high-speed (100MB/s+) connection between the Data Server & the Database Server.
Data Server:
The customer will need the data server to be installed in a central location that is accessible from all of the sites. There could be multiple data servers serving this purpose, but all of them must be located in the same physical LAN as the Database Server. The Data Server service can also be installed on the same machine that SQL Server is installed on. Application Server:
Wide Area Network/Multi-Site environment that is not using Thin-Client computing, but is instead connected via Private Point to Point lines, VPNs, or other WAN
technology based on TCP/IP.
The customer will need an application server to be installed at every site. This application server must have TCP/IP access to the Data Server, and while the connection can be a low speed connection, it must still be broadband speeds (1MB/s+).
Page 5 Batch Scanning Server:
The customer will need a Batch Scanning server installed at every site if and only if it is using PaperSave batch scanning features such as ScanFirst™ or ScanLater™. The batch scanning server must sit in the same physical LAN as the application server.
Batch Scanning Server:
The customer will need a dedicated Batch Scanning Server, whose specifications match the specifications of a Medium/High-Usage Batch Scanning Server. Details on these are outlined in the PaperSave® Recommended Hardware Guidelines section of this document.
Imaging Hardware: The customer needs to
process 50+ stacks of ScanLater™ or ScanFirst™ coversheet separated documents a day or the individual stacks submitted to the Batch Scanning Server through ScanFirst™ or ScanLater™ are 50+ pages in size (50 page MTIFFs).
The customer will need a scanner capable of handling large volume of scans at high speeds. A high-volume workgroup scanner is therefore a requirement for this scenario. Details on High-Volume scanners are outlined in the PaperSave® Recommended Hardware Guidelines section of this document.
PaperSave® Client: The customer requires the
performance of High-End scanning at the desktop using ScanNow™. High End Scanning is defined as the scanning (using ScanNow™) of documents that are in grayscale, or color, or are greater than 600dpi, or are 10+ pages on average.
The PaperSave® Client using ScanNow™ must be installed on a higher-end workstation fit for high-higher-end imaging applications. Details on this are outlined in the PaperSave® Recommended Hardware Guidelines section of this document.
PaperSave® Client: The client would like to
install & use the PaperSave® client within a thin-client computing environment such as Citrix Presentation Server or Microsoft Windows Terminal Server.
Most versions of Citrix and all versions of Microsoft Windows Terminal Server Remote-Scan lack support for TWAIN over their respective remote desktop protocols (ICA & RDP respectively). To bridge this gap in peripheral support a third party TWAIN over ICA or TWAIN over RDP component such as the one sold by Remote-Scan ( www.remote-scan.com) is required in order to allow ScanNow™ to work over the thin-client session.

PaperSave® Recommended Hardware Guidelines:
The following table outlines the recommended general hardware configuration for each PaperSave® component under potentially different usage requirements. Please note that multiple PaperSave®
components can be installed on the same computer as long as the computer meets the recommended requirements outlined for the most resource intensive component installed on that computer. Exceptions to this rule are specifically outlined in the PaperSave® Enterprise Recommended Deployment Guidelines section of this document.
Microsoft SQL Server Database Server:
This is the server that has Microsoft SQL Server installed on it, and is hosting the PaperSave® database. These specifications assume that the SQL Server is used as a shared SQL Server, and that it may also host databases other than PaperSave®'s. However, there are enterprise scenarios that would require that a customer use a dedicated Microsoft SQL Server machine that hosts the PaperSave® database exclusively. These scenarios are described in this document under the section titled PaperSave® Enterprise
Recommended Deployment Guidelines.
