CHAPTER 1

Theory of Operation

The Chapter presents an overview of the PRISMA Compliance, its

capabilities, main technical features and specifications.



The following topics are included in this Chapter:

1.1 Introduction 2

1.2 Operating Principle 4

1.3 Database Architecture 5

1.4 Replication 7

1.5 Licensing 8

1.1  Introduction

The PRISMA Compliance timing solution offers efficient data collection and logging, resilient

storage, flexible data retrieval, and analysis. PRISMA Compliance is a complete and universal

software tool to document the ongoing changes in your timing network’s fidelity to UTC, cov-

ering all timing elements, and thus satisfying current MiFIDII, ESMA, MiFIR, and FINRA com-

pliance regulations, as well as internal compliance needs.

Spectracom's PRISMA Compliance solution comprises:

a QuasarDB

®

fast database that is designed to manage large amounts of data

a timing data transmitter software that feeds the relevant timing data from timing network

grandmasters and clients to the database

customized retrieval software allowing the user to access data and generate reports.

1.1.1  Real-Time Reporting and True UTC Traceability

PRISMA Compliance was built from the ground up using a highly scalable, low latency Quas-

arDB

®

time series database, capable of collecting and organizing your data in real time. Cus-

tomer interaction with PRISMA Compliance software is fast and efficient; you can generate a

report in seconds, rather than hours.

PRISMA Compliance provides full UTC (Coordinated Universal Time) traceability by collecting

and aggregating all relevant information within your timing chain to provide you with the true

offset to UTC (beyond the offset from master to client). This traceability to UTC is required by

the latest regulations.

1.1 Introduction

Figure 1-1: Timing chain offset

1.1.2  Basic Structure

Figure 1-2: PRISMA Compliance Transmitters and Servers

Network timing data is aggregated by the PRISMA Compliance Transmitter installed on

timing grandmasters, masters and clients within a local network.

The Transmitter pushes the captured timing data to a PRISMA Compliance Server where

the data is replicated onto other Compliance Servers.

Users can access the stored data via an interface to generate customized reports (see

"Generating Reports" on page35).

1.1 Introduction

CHAPTER 1 • PRISMA Compliance User Guide Rev. 2.0

1.1.3  Transmitter Compatibility

PRISMA Compliance Transmitters run on Linux and Windows and are fully compatible with

NTPd, Timekeeper, chrony, ptpd, ptp4l, and sfptpd. This makes PRISMA Compliance a drop-in

timing compliance solution for most timing networks, whether it’s an older legacy NTP network

or a new, low latency PTP deployment. See "Network and System Requirements" on page12

and the "Installation Summary" on page14 for more information.

1.2  Operating Principle

PRISMA Compliance is comprised of two basic parts. On the receiving end, at least one Quas-

arDB database Compliance Server instance is installed on a server (also referred to as node).

On the sending end, PRISMA Compliance also uses at least one Compliance Transmitter installed

on a timing server or client that pushes the logged compliance data to the Server.

For standard applications, you will use two Compliance Servers, to allow for redundancy (a

replication factor greater than 1), and one Compliance Transmitter installed for each timing cli-

ent (to allow for truthful monitoring). There is no theoretical upper limit for the number of time

Compliance Server nodes and Compliance Transmitters (while observing the licensing require-

ments (see "Licensing" on page8).

Compliance Transmitters are programs that you install in your timing network. The Transmitters

collect synchronization data from the timing network on which they are installed, and send this

data to the Compliance Server(s), where the data is archived and can be accessed by users.

The data transmission can be scheduled during off-hours or throughout the day (see

"Scheduling Transmitter Functions " on page29).

CHAPTER 1 • PRISMA Compliance User Guide Rev. 2.0

1.2 Operating Principle

The Compliance Server(s) collect the timing data and store it in the high-performance

QuasarDB database.

A database replication automatically occurs between all Compliance Server nodes,

provided they are balanced properly (see "Database Architecture" below).

Reports are generated from a local application on a Compliance Server, or via an API

(see "Generating Reports" on page35).

Figure 1-3: Transmitting timing data

1.3  Database Architecture

Compliance Servers store compliance data that has been pushed by the Compliance Trans-

mitter which are installed on timing network clients or servers. A Compliance database Server

running a QuasarDB instance is called a database node. Nodes can be installed in one geo-

graphic site, or across sites in different locations (depending on the license purchased; for

more information, see "Licensing" on page8). While one node will suffice to store all timing

data from a monitored network, it is more efficient and safer from a redundancy standpoint to

use multiple nodes which are linked together in a cluster. In such a peer-to-peer cluster, the data-

base nodes are self-sufficient by sharing data and handling all client requests, thus providing a

scalable, concurrent, and fault-tolerant database.

The nodes in a cluster need to be arranged such that they have equal distances to one another

(they are "balanced"), in order to distribute the data storage load evenly:

1.3 Database Architecture

CHAPTER 1 • PRISMA Compliance User Guide Rev. 2.0

5

Figure 1-4: Database cluster architectures

Database servers must be indexed by node ID’s which look like fractions: The server ID is the

numerator and the # of servers in the cluster in the denominator. (For instance, an ID of ¾ cor-

responds to the 3rd server in a cluster of 4 servers.) For balanced operation, where roughly the

same amount of data is installed on each server, it is recommended that each position in the

cluster have a server associated with it.

1.3.1  Compliance Server Node IDs

The syntax of the node ID's is: [current_node]/[total_node] (e.g., 3/8 for the third

node of a cluster with 8 nodes).

QuasarDB will assign an indexed node ID automatically, using the relative position of the new

node. For example, if you have a cluster with 4 nodes, each node should be assigned the fol-

lowing ID:

node 1: 1/4

node 2: 2/4

node 3: 3/4

node 4: 4/4

If you want to reserve ID space to allow the cluster to grow to 32 nodes without changing all IDs

later, you should assign the following numbers:

node 1: 1/32

node 2: 9/32

node 3: 17/32

node 4: 25/32

(See also: "Configuring the Servers" on page22)

CHAPTER 1 • PRISMA Compliance User Guide Rev. 2.0

1.3 Database Architecture

1.4  Replication

Regulations in both the US, and Europe require that all relevant logs from reportable events are

stored for at least 5 years and can be retrieved when requested. By nature, the Compliance

Servers only store each piece of information once; they avoid duplication of information

because the Compliance Transmitters do not retrieve data that is recognized as already exist-

ing in the node.

To allow for data to be present within storage in more than one place, PRISMA Compliance

supports data replication, allowing for the logs to be stored on more than one Compliance

Server for resiliency purposes. Replication is recommended, as it ensures that data will not be

lost if a single Compliance Server node fails. Once replication has been set up and the data-

base cluster has been stabilized, replication occurs automatically between Compliance Servers.

Figure 1-5: Replication principle: No/partial/full replication

The concept of data being stored in more than one place in the database cluster is referred to

as replication. A replication factor of 1 means that each piece of data will only be stored on a

single node of the cluster (zero redundancy). If data is lost on a single node of the cluster, that

data cannot be recovered.

A replication factor of 2 means that each piece of data will be stored on 2 nodes in the cluster.

The cluster must have at least 2 nodes in order to support this level of replication. If a single

node fails, then once that node is replaced (with the same node ID) it will be re-populated with

data to support the necessary replication factor.

Replication factors of 3 and 4 and so on are also supported, with each piece of data being

stored on 3or 4 nodes, respectively.

It is necessary to have at least as many nodes installed as your replication factor setting. To reduce

the amount of data on each node, you may also choose to install more nodes than your rep-

licated data, so that each node only holds part of one full copy of the data.

The nodes in a database cluster are arranged in a ring-shaped database (see figure above). If

a timing log file is added to node 1/3, it will be replicated to node 2/3 (replication factor =

2), and to 3/3 (replication factor = 3), etc. Thus, replication linearly increases disk and

memory usage.

Data that is transmitted to a database with replication enabled will not be made available in

reports until replication is complete.

1.4 Replication

CHAPTER 1 • PRISMA Compliance User Guide Rev. 2.0

7

In the event that a node fails or when entries are otherwise unavailable, client requests will be

served by the successor node(s) containing the duplicate data. In order for an entry to become

unavailable, all nodes containing the duplicate data need to fail

simultaneously

.

In each of the following examples, the network has three nodes (Compliance Servers) installed.

The data distribution occurs differently within each node depending on the replication factor.

As the replication factor increases, so does the amount of data on each node.

2.2 Installation Summary 14

2.3 Installing a Compliance Server Package 14

2.4 Installing a Compliance Transmitter 18

2.1  Network and System Requirements

2.1.1  Compliance Transmitter Requirements

The Transmitter software that is installed on the network timing clients and grandmaster require

one of the following timing clients on each node.

Timing networks running NTPd, TimeKeeper, chrony, PTPd, PTP4L, and sfptpd are supported.

CPU:

Intel Westmere (2010) or better microarchitecture (AMD Bulldozer or better) – database

API requirements

OS:

Linux (deb/rpm/tgz): Requires glibc 2.12 and x64 (2010) or later

Windows:

x64 (32-bit not recommended)

Windows 8 or later; not tested on earlier versions

Windows Server 2012 or later; not tested on earlier versions

2.1.2  Compliance Server Database Node Requirements

PRISMA Compliance database software can run on virtual servers and physical servers. The

ISO installation bundle will install a full CentOS7 version on each server.

*Your space requirements will vary depending on the amount of data collected and length of installation.

Note: Some real measurements can be found here: "Sample Storage Meas-

urements" on page38.

If a client has a single source with one record per second, then it would require 1.5 GB to store

one year worth of data.

12

CHAPTER 2 • PRISMA Compliance User Guide Rev. 2.0

2.1 Network and System Requirements

Size of Client Data in Cluster = ~1.5 GB * Records per second * Years * Sources amount

Total Size of Data in Cluster = SUM (Size of Client Data in Cluster)

E X A M P L E :

If the requirement is to store 7 years of data for a client with 3 sources (1 record per second), and a

server with one source (2 records per second):

Size of Client Data = 1.5 GB * 1 rec/sec * 7 years * 3 sources = 31.5 GB

Size of Server Data = 1.5 GB * 2 rec/sec * 7 years * 1 sources = 21 GB

Total Size of Client Data + Server Data (with a replication factor of 1) = 31.5 GB + 21 GB = 52.5 GB

In this example, the HDD requirements for a single node cluster would be:

Minimum = 10 GB + 105 GB + 20% = 76 GB

Typical = 10 GB + 105 GB + 30% = 82 GB

The HDD requirements for a cluster with 4 nodes and a replication factor of 2 would be:

Minimum = 10 GB + 52.5 GB * Replication Factor of 2 / 4 nodes + 20% = 10 GB +

26.25 GB + 20% = 51 GB per node

Typical = 10 GB + 52.5 GB * Replication Factor of 2 / 4 nodes + 30% = 10 GB +

26.25 GB + 30% = 55 GB per node

Note: The total amount of data a single grid may handle is 16 EiB (that is

18,446,744,073,709,551,616 bytes).

Information on cluster configuration can be found under "Database Architecture" on page5.

2.1.3  Timing Network Requirements

All Compliance Servers (database nodes) must be time synchronized. It is necessary to

have functioning NTP on your network to achieve accurate records.

If your system is using Windows, it is necessary to have Windows 8 and Windows Server

2012 or better for the operating system to deliver highly accurate timestamps, which pre-

vent transaction conflicts and provide entries with accurate metadata.

2.2  Installation Summary

2.2.1  Compliance Servers

The PRISMA Compliance Server software is distributed as an ISO package based on CentOS7.

The ISO will install a full Linux system on your virtual machine or on a physical server. The

PRISMA Compliance Server software includes the database software and the Spectracom soft-

ware that generates the logs. Your license file is delivered separately.

Once the installation is complete, you can then add the appropriate amount of nodes for your

network (see "Configuring the Servers" on page22). For standard applications you need to

configure only a few database settings. See "Installing a Compliance Server Package" below

for more information.

2.2.2  Compliance Transmitters

PRISMA Compliance Transmitters are installed on the network timing clients, masters and grand-

masters. Available for free download as a companion to the Compliance Server, Compliance

Transmitter files gather timing data in your network. You will install the Transmitter that is

designed for your timing setup, and enter settings to ensure data collection. See "Installing a

Compliance Transmitter" on page18 and "Configuring the Transmitter" on page25 for more

information.

For Technical Support contact information see "Technical Support" on page38.

2.3  Installing a Compliance Server Package

Note: The following instructions are designed to apply to installation of both your

first Compliance Server (database node) and your additional servers. If you plan

on installing multiple Compliance Servers, you must install, configure, and start

the first server prior to installing additional servers. See "Configuring the Serv-

ers" on page22 for more information.

The Compliance Package is provided as an ISO file. The ISO file can be installed on a virtual

machine (VM), or on bare metal hardware. Attach a hard drive of sufficient size.

1.

Verify that your network, and your server meet the minimum requirements outlined under

"Network and System Requirements" on page12.

2.

Prepare the target device to boot from the provided ISO file. For VM’s, attach the ISO

directly to the virtual machine instance. For physical servers, write the ISO to media the

server can boot from.
