(services) running on your servers. Web traffic is directed only
to servers with healthy services, guaranteeing the best Quality
of Service to your clients.
Dual Configurations
SysMaster can additionally work in configuration together with
secondary SysMaster devices to act as backup if the primary device
fails or goes down. For dual configurations, SysMaster works in
active/active and active/standby modes.
The SysMaster NC 9000 offers exceptional
scalability and flexibility.
- Server Level Scalability
Additional servers can be added to the cluster on the
fly, or they can be taken out of service for upgrade or maintenance
without disrupting or affecting the quality of service.
- Traffic Level Scalability
When web traffic increases, you can easily add another server
to the cluster to achieve the necessary performance gain instead
of upgrading to expensive hardware. This way, your web site infrastructure
can easily grow along with the demand for its services, while
protecting investments made in existing hardware.
- Platform Level Scalability
The SysMaster platform offers easy integration with multiple heterogeneous
hardware platforms, allowing organizations to protect their investments
in legacy hardware installations, as well as easily integrate
future hardware investments.
The SysMaster NC 9000 is easy to set up, and easy
to manage. It is a self-contained 'plug and play' appliance that
doesn't require the additional installation of software on your
servers. Network management is made easier, too, because administrators
can deploy new servers, and take individual servers offline for
routine maintenance without disrupting service to end users.
Secure Management
The SysMaster NC 9000 provides secured interface for management
by means of a robust authentication mechanism for granting access
to system resources implemented through Access Control Lists.
SysMaster management consoles provide the tools for access and
management of all device settings. SysMaster has two management
consoles - web based and VGA menu based.
Simplified Management
The SysMaster NC 9000 centralizes the management of server resources
and devices such as firewalls, proxy servers and caches. End users
are directed to a single virtual address, easing network administration
and maintenance.

High-volume web sites usually consist of
multiple servers or server clusters providing the same service from
synchronized contents. With the SysMaster NC 9000 all these servers
are addressed from the Internet using a single Virtual IP address.
SysMaster loadbalances the traffic for this IP among the servers
based upon the workload, and the processing capabilities of the
individual servers. SysMaster uses both static and dynamic algorithms
for optimized loadbalancing.
Direct Path Routing
Network Address Translation
Direct-Path Routing mode for High Speed
loadbalancing
SysMaster takes into account the individual capabilities of every
server. This allows administrators to put servers with varying
capabilities in one cluster thus obtaining optimum performance
and high utilization of the available resources along with investment
costs reduction. To increase the overall throughput of the server
cluster, the SysMaster NC 9000 implements the Direct-Path Routing
technique allowing servers to send responses directly to the clients
without passing traffic through the loadbalancing device.
NAT loadbalancing
The great advantage of NAT is that real servers can run any OS
that supports TCP/IP protocol. The only requirement for the real
servers is that they should use SysMaster as their default gateway.
Another advantage is that real servers use private IP addresses
and ports, which increases security and conserves real IP addresses.
Advanced Flexibility - Huge variety of balanced
traffic
SysMaster supports the following IP Protocols:
Web (http), FTP, UDP, DNS, E-Mail, LDAP, TCP,
SSL, Streaming Audio, Streaming Video and others.
Advanced Flexibility - Huge variety of balanced
devices
SysMaster allows for loadbalancing a vast number of different
types of network devices:
- Web servers;
- Firewalls;
- Routers;
- Cache servers;
- Proxy servers;
- Multimedia servers;
- VPN;
- NFS;
- LDAP servers;
- Others.
Security
SysMaster has an inherently high level of security because
using it, administrators can build high performance server arrays
that can failover easily. This is a much more viable and scalable
solution than using only one or two powerful but expensive servers
whose failure can be critical.
Persistence
SysMaster integrates another feature allowing your users to resume
their connection to the same server they communicated with. SysMaster
offers two modes of persistence: Source-Server and
Mega Proxy Sever Persistence - Big enterprises and
ISPs use loadbalancing across multiple proxy servers to connect
to the Internet.
High Speed
Direct-Path Routing Performance
The SysMaster NC 9000 includes a loadbalancing mode called Direct-Path
Routing. This mode allows servers to bypass SysMaster when returning
traffic to the client. This method allows for supporting an
increased number of simultaneous connections that translates
to greater throughput of your services as a whole.
Easy Performance Upgrades
Internet traffic demands are advancing rapidly. The SysMaster
NC 9000 is ready, thanks to its unique hardware/software module
design which allows organizations to achieve performance gains
without having to upgrade expensive hardware.
|
Built-in Network Cache Controller |
|
|
|
The SysMaster NC 9000 loadbalances user
requests to the cache server best able to process the requests.
If the requested data is not available locally, the Proxy server
retrieves it from the Internet, and then redirects it to the end
user which requested it. The whole process remains totally transparent
for the end user. The SysMaster facilitates this process by efficiently
decreasing the latency time from requesting Internet content to
actually receiving it.
|
Global Scalability and Availability |
|
|
|
The unique architecture of the SysMaster
5000 allows loadbalancing to be performed on both a local and global
basis. Utilizing the Global IP Tunneling feature of SysMaster, real
servers can be geographically distributed, maintaining uninterruptible
service even when site-wide failure occurs.
|
Firewall and Security Module |
|
|
|
The firewall module of SysMaster acts in
both incoming and outgoing directions. Network administrators can
grant Internet access for corporate networks only to selected "trusted"
locations, or public access can be limited to selected "safe" services.
On the other hand, outgoing traffic can also be filtered to protect
valuable data.
Security
SysMaster provides solid security to Enterprise networks utilizing
various security mechanisms.
Extensive set of attacks that SysMaster
handles
SysMaster is designed to protect itself from attacks
and provide protection for the servers being loadbalanced. Basic
functionalities include:
- Specially designed core software for advanced
security;
- Packet Filtering (IPFW);
- Security script identifies any services/ports
being probed;
- Default deny device - tight control of traffic
allowed to pass through;
- Administration through Access Control Lists;
- Protects itself and servers from ICMP attack
(thwarts ping attacks);
- Can reap idle connections (thwarts Denial of
Service attacks);
- Can perform source route tracing (thwarts IP
spoofing);
- Unacknowledged SYN without ACK buffers (thwarts
SYN floods);
- Thwarts teardrop and land attacks;
- Can map well known ports to any ports on the
servers (Port mapping);
- Real Servers IP addresses can be hidden from
the public;
- Not running SMTPd, FTPd, or any other attackable
daemons.
SysMaster NC 9000 as a Gateway in NAT mode
SysMaster NC 9000 connects local corporate networks to the Internet.
Corporate computers have private IP addresses and are not directly
accessible from the global network. LAN users access the Internet
through SysMaster NC 9000. SysMaster rewrites packets as they pass
through it, so that they always seem to come from the device itself.
It then rewrites the responses so that they can reach the original
recipient.
SysMaster allows for all managed servers to be visible
via a Virtual IP, and on specified ports that can be easily enabled
and filtered, resulting in enhanced security.
In Network Address Translation mode, well-known
ports such as 80, 443, 20, and 21 can be mapped to any port number
on the actual servers. This provides greater security by making
it difficult for intruders to identify what services are running
on which port.
|
Quality of Service Module |
|
|
|
Bandwidth Management and Denial of Service Prevention.
The SysMaster NC 9000 uses IP QoS together with
TCP and UDP level filtering to implement Bandwidth Management
and Denial of Service Prevention.
Bandwidth Management - SysMaster manages
incoming and outgoing traffic by filtering traffic using specified
sets of filter parameters for refined bandwidth utilization and
restriction policies. The QoS module supports the DiffServ
protocol provisioning for the proper treatment of the DiffServ marked
IP packets throughout the core network of the Internet.
Denial of Service Prevention
- SysMaster provides extended capabilities for filtering
out any malicious attacks based on TCP, UDP, IP, and ICMP protocols.
This greatly improves the security of your network resources, and
guarantees that such attacks will not disrupt the normal operation
of your systems.
