Route Analytics Management System 8.10

RAMS 8.10 includes the following major, new features:

Enhancements to the VPN traffic feature

This release adds three significant enhancements to the VPN Traffic feature introduced in the 8.01 release. VPN Traffic provides comprehensive network-wide visibility within an MPLS core to traffic by Customer, by CoS, by Source and/or Destination PE, and by Application group. A rich set of analytic tools and reports help the Network Engineer and Network operator to monitor, analyze, and manage the MPLS core infrastructure. The operator can also set alerts based on various traffic conditions such as aggregate volume, traffic by CoS, etc., and be notified when such conditions are met.

The following enhancements for VPN Traffic are added in the 8.10 release:

Enhanced Network Discovery using SNMP

In this release we provide an additional recorder to collect static network topology information from the routers using SNMP. The list of routers that will be queried by this recorder is constructed by the RAMS appliance from its knowledge about routers participating in IGPs or BGP. The list may be filtered by user configuration.

The information collected includes router names, software versions, interfaces (type, address and speed), and optionally, static routes. This information was available previously for EIGRP networks but not OSPF or ISIS. Now the information collected with SNMP is presented in the same manner as it was for EIGRP in the various GUI reports and in the node and link info panels on the topology map. The interface speed is used to automatically determine link capacity for traffic utilization calculations.

Links are created between routers having interfaces with matching prefixes so that network areas connected only by static routing will become connected on the map.

The SNMP collector will query routers periodically with a period specified by the user so that the recorder will not place an inappropriate load to the routers that it queries. SNMP v2 or v3 can be used to query the routers. The SNMP v2 community strings and the SNMP v3 profiles are configured by the user.

In a distributed RAMS deployment, multiple SNMP collectors can be configured to query the separate areas of the network.

In this release, the User's Guide has been split into two books:

Hardware Requirements

Before installing RAMS or Traffic Analysis, make sure that your system meets the following minimum requirements:

Supported Hardware Platform in descending list of preference:

  1. HP ProLiant DL 380 G5
  2. DL 360 G5
  3. DL 380 G4
  4. DL 360 G4p
  5. DL 360 G4
  6. DL 360 G3

NOTE: Starting with the release of RAMS 8.01, the hardware component requirements specified in the RAMS 8.01/RAMS 8.10 Support matrix must be adhered. Problems related to inadequate hardware configuration which do not follow the recommended guidelines will not be supported.

Disk Configuration of RAMS appliance

IMPORTANT: Consider your disk space requirements and fault tolerance needs and ensure that all available physical drives are installed before powering up the HP ProLiant server for the first time.

Starting with the RAMS 8.01 release, the Flow Collector is only supported on a DL 380 G5 hardware platform. RAMS will require two logical drives be configured for a Flow Collector unit - the first logical drive must be set at RAID 1 + 0, the second logical drive set at RAID 0. If you have an existing Flow Collector unit running a pre-6.1 software version, you must re-configure the server with two logical volumes and install the 6.1 software version from a CD image. Failing to do so can cause unexpected behavior. Cases reported as such will not be supported.

When using a DL 380 G5 hardware platform as the Flow Collector unit, it is required that the HP RAMS Flow Collector HiCap SW LTU license be purchased and installed.

For all non-Flow Collector units, RAMS will only utilize a single logical drive as configured on the ProLiant DL380/360 hardware; this means any extra physical disks configured in a second logical drive will be not be recognized by RAMS.

For detailed steps to configure a RAMS 8.10 Flow Collector, it is recommended that you use a HP Proliant SmartStart CD (shipped with the server). The SmartStart CD provides a more comprehensive Array Configuration Utility interface. Please refer to instructions in the RAMS Appliance Setup Guide.

The following describes a quick way to configure a single logical drive.

During the initial power-up of a new server, an auto-configuration process uses all of the physical drives on the HP Smart Array controller to set up a single logical drive. The default RAID (fault tolerance) level used for the logical drive depends on the number of physical drives as listed below:

* The available disk space is ~5% less than the disk's reported size. Every physical drive in an array will have the usable capacity of the smallest drive in the array.

NOTE: Multiple drives configured as a RAID 0 striped set will provide maximum disk space but will NOT provide any fault tolerance. If you install more than one drive intended for maximum disk space usage, i.e., not for fault tolerance, you MUST configure to use RAID 0 or the hardware will default to RAID 1 +0.

During the initial hardware boot sequence, you have the opportunity to accept the default logical drive configuration as shown above, or you can create the logical drive based on your drive space and fault tolerance needs. Watch for the following message during the boot process:

Slot 0 HP Smart Array Controller

Press <F8> to run the Option ROM Configuration for Arrays Utility

Press <F7> to Accept the default configuration - 2 drives in RAID 1 +0

Refer to the HP Smart Array Controller Reference Guide for configuration options and details.

IMPORTANT: Make sure the logical drive is configured as needed before installing RAMS. Any changes to the logical drive configuration, e.g., adding drives or changing the RAID level, will require a reload of the RAMS software and a restore (from backup) of the RAMS configuration and databases.
