ADMINISTRATOR QUICK START GUIDE 6

4 REQUIRED / RECOMMENDED HARDWARE

The following hardware specifications are defined per one server within a LAN. A multi-server environment is

required for higher numbers of connected devices.

HW server sizing is based on approximately 10,000 pages per device (monthly) and an average of about 20

users per device.

The sizing is based on several premises (click to expand)

1. MS Windows Print Queue represents print input-output-queue in the operating system. It really

represents a mere mechanism to provide the print driver to a client software (e.g. to create PCL/PS

file, receive the print data stream over network, store it on the hard drive, and serialize it to the

printer. According the Microsoft print server Sizing Overview (http://technet.microsoft.com/en-

us/library/cc783748(v=ws.10).aspx), one can have about 1500 queues on single server and 2500 on

clustered system. The number of connected clients, network throughput and hard disk speed is the

biggest resource constraint. Of course the document is outdated, so we can expect slightly higher

capacity on new systems.

2. YSoft SafeQ Print Queue represents a name in the database that may be related to a printer,

terminal (reader) or group of users. From a windows print queue perspective, this would represent a

(LPR) queue name in the print queue backend. YSoft SafeQ server has an internal mechanism how to

balance the load by partially serializing the incoming traffic; in theory there is no limit on how many

windows print queues can be connected to the SafeQ server.

3. YSoft SafeQ Network Device (printer/mfp) represents a physical printing devices or multifunction

printer with terminal / card reader. YSoft SafeQ server pushes/queues print jobs to this device or pulls

the print jobs from the server upon user's request at the terminal. One network device typically

represents one or multiple Windows Print Queues.

4. YSoft SafeQ CML Server -- represents a YSoft SafeQ Server app installed on a physical or virtual server

(may be print server). CML server includes a SQL database to track all prints (contains relation among

users, printers, readers and print jobs), LPR subsystem to receive prints from a Print Server (or client

workstations), administrative Web interface, system for managing the request from terminals and

readers (provides user authentication and list of applicable print jobs to be pushed to the devices) and

LDAP integration subsystem. YSoft SafeQ server can handle up to 200 network devices on a single

server and up to 1600 on a 4-server CML system. Reasonable hardware or virtual platform is needed

(dual/quad core 2GHz+ processor, 6GB RAM, 500 IOPS storage).

5. YSoft SafeQ ORS Server -- represents a YSoft SafeQ Remote Spooler Server app installed on a physical

or virtual server (may be print server). Remote spoolers can build roaming groups (clusters) and can

handle up to 2000 devices on 25-node system. A single ORS server can handle up to 50 network

devices (80 devices on a YSoft approved hardware platform). Remote spoolers can generally handle

much lower amount of traffic, however are usually more reliable that CML system as they don't have

any external dependencies web server, SQL database or LDAP (not taking CML connection into

account).

This section describes resource usage by YSoft SafeQ in various configurations.

Do not use for server sizing unless you know what you are doing. A sizing guide based on these numbers is

under preparation.

In case Virtual devices are used, the virtual machine should have dedicated resources. Virtual

machines with shared resources may not handle the load and significantly impact end user

business.

The most critical resource for the system is disk. Having at least 300 IOPS storage is in general

mandatory.

Depending on the load, the system requires server resources. It is mandatory to have free processing power for

the YSoft SafeQ application (at least 30% continuous for ORS up to 30 devices and 50% continuous for

CML/ORS and more than 30 devices).

o Windows 2003/2003R2/2008 32bit including clustered installation

o Windows 2003R2/2008/2008R2 64bit including clustered installation

o Windows 2012 Not currently supported, for details, please contact YSoft R&D

Workstation operating system for YSoft SafeQ ORS v4.0 up to 10 connected devices.

o Windows XP SP3/7 32bit

o Windows XP SP3/7 64bit

5.1 NOTES

Microsoft .NET 4.0 is required for embedded terminal and vendor-provided accounting support.

YSoft SafeQ ORS installation always require .NET 4.0 support.

YSoft SafeQ 4 does not yet support Linux-based operating systems.

For windows XP and Server 2003 is required Windows Imaging Component.

When you are sure your system meets all the prerequisites, you can begin the YSoft SafeQ installation. With

the interactive installer, all you need to do is to run the installation file and follow the steps in the installation

wizard. You can choose between the default installation or a customized installation. The default installation

will install YSoft SafeQ with the recommended settings, but with a customized installation, you can set all the

settings yourself.
