The maximum capacity and throughput of your Landslide system is dependent on the system configuration and test applications purchased/licensed. The capacity and rate specifications that are described throughout this documentation are the maximum capacities and rates available with a standard system configuration. These numbers represent the maximum capacity and rate attainable under specified ideal conditions (actual results will vary). The following topics are included:
The flexibility of the Landslide system allows you to add precisely the number of Landslide Test Servers required to fully stress the capacity, maximum rates, and stability of the systems under test.
To determine the full capacity of your system, multiply the Test Server capacity by the number of Test Servers in your system.
| NOTE: Contact your support personnel for performance numbers and maximum capabilities of the various test applications. |
Up to 128 Landslide Test Servers can be controlled by the TAS (see table below).
The number of processes that can be supported is based on the TAS type and Test Server type.
Note, a C50-S4 / C50-S5 TAS cannot manage 2 C50-S4 and 32 E10 and 10 v-small TS. It can manage 2 C50-S4 or 2 C50-S5 or 32 E10 or 10 v-small TS. This is the case with all TAS and TEST server types listed in the table below, it is an OR situation across the columns. See table below:

96 users can be simultaneously logged in to the TAS (The combination of (Tcl API + GUI Clients <= 48) + (REST (Web) Clients <=48) must never result in more than 96 client connections to the TAS in the same instant)
One Test Server can support 4 simultaneous test sessions running on the same process when Reserve Process is not used or 1 test session per process when using Reserve Processes. When using Reserve process, the Max number of test sessions per Test Server equals the number of Test Server processes which varies per system (1 for vTS, and up to 8 for C100 M4). See table above for Maximum simultaneous Test sessions supported per TAS type.
128 user accounts can be defined
1024 Systems Under Test (SUT) can be defined
The Landslide C50-S4 or C50-S5 system, provides a solution for test beds requiring small scale with functional test flexibility and includes/supports as follows:
|
NOTE: There is no fixed limit on the number of Test Cases a Test Session can support. However, the actual number would be based on your client and TAS memory/usage. In a standard system configuration, you may easily test with up to a 100 TCs in a single test session. The maximum number of simultaneous Test Cases supported on a single Test Server can vary from 1 to 100 depending on the configuration and system resources reserved for individual Test Cases. System resources are reserved in 1% units. If an individual Test Case uses less than a full percentage point, the percentage will be rounded to the nearest whole number. |
Landslide provides different levels of session capacity testing and data performance. This allows you to provision (to license) the Test Servers to optimally meet your session capacity and data performance needs.
The Landslide standard multi-server license allows you to choose between the following:
This is the basic, out-of-the-box capacity and data performance levels achieved by a test server
This license option increases a test server’s standard base capacity by a factor of two
Performance Accelerator is licensed on a per-server basis, that is, to attain increased session capacity
Performance Accelerator is a floating license and may be assigned to any system Test Server
Performance acceleration is attained using four processes on C100 M4
The C100 M4 Extreme License increases a Test Server's base session capacity and data performance.
C100 M4 Extreme Capacity License is a floating license and may be assigned to any C100 M4 Test Server
On C100 M4 Test Server appliances Extreme Capacity is attained using four or eight processes
The C100 M4 Ultra Extreme License increases a Test Server's base session capacity and data performance.
C100 M4 Ultra Extreme Capacity License is a floating license and may be assigned to any C100 M4 Test Server
On C100 M4 Test Server appliances Ultra Extreme Capacity is attained using four or eight processes
Performance Accelerator ( C100 M4), Extreme Capacity ( C100 M4), and (C100 M4) Ultra Extreme are floating licenses and may be assigned to Test Servers when they need increased capacity and performance. The actual session capacity and data performance levels attained by a Test Server depends on hardware platform, operating system and physical memory size in addition to Performance Accelerator or Extreme License.
|
NOTE: The data throughput numbers listed do not apply to applications bound by the hardware constraints of the IPSec accelerator card. |
| IMPORTANT: The maximum rates can only be achieved when a Landslide Test Server is executing a single test. When multiple tests are executed, they share the server's capacity and resources. The additional processing overhead of managing multiple tests will not affect the maximum capacities, but will affect the maximum rates that can be achieved in each test. |
The C100 Test Servers and the mXP Module Test Servers are licensed separately on Landslide. The mX/mXP module licenses are referred to as Landslide mX Licenses (LS mX). Each mX /mXP module requires one Landslide mX License, it is a per module license, not a per chassis license.
The total number of supported test servers on a single Landslide Test Manager remains at 32. Both the pool of C100 test servers and the pool of Landslide MX Licenses combined must be less than or equal to 32.
For each mX/mXP module to be added as a test server in a Landslide test manager, that test manager must have an unused Landslide mX license available to assign to the new mX/mXP module. These licenses are independent of STC chassis. If you have 4 LS mX licenses you may have 4 mXP modules in 1 STC chassis or even 1 mXP module in each of 4 different STC chassis. There is a performance difference between an mX and a mXP module but both require the same Landslide mX License.
LS mX licensing is part of the standard Landslide Test Manager Licensing process similar to C100 Test Server licensing.
NOTE: Landslide mX supports a single license level that includes maximum capacity. However, an mX module will have lower licensed UE capacity than an mXP module because the mXP modules have been optimized for higher Ladnslide Plus Spirent TestCenter performance. Landslide mX License does not support Performance Accelerator or Extreme Capacity tiered licensing. |
The actual session capacity and data performance levels of a test server depend on the hardware platform, operating system and physical memory size in addition to the Performance Accelerator or Extreme License.
Please contact Spirent Support for more information on OS upgrades.
Landslide supports generations of appliances:
| The Spirent C100 M4 | Configured/Imaged with a 64-bit Operating System. |
| The Spirent C100 M4 | Factory configured with 512GB of physical memory. |
The data throughput and performance measurements for different Landslide releases show data gathered using a test methodology that achieves the maximum throughput — a Capacity test where in the data traffic starts after all connections have been established. These rates cannot be achieved when the test system is simultaneously processing control and bearer plane traffic.

NOTE: UMTS test case supports a maximum of 1000 BSS and 1094 NSEIs per BSS. However, these two maximums are not supported at the same time. A combined maximum of BSSs and NSEIs (NSVCs) must be less than 20,480. For example:
