Junos Space JA1500 Appliance Overview

The Junos Space JA1500 appliance is a Juniper Networks, dedicated, physical, hardware device that is engineered to provide the computing power and specific requirements needed to install and run the Junos Space application. The JA1500 appliance all-in-one design makes the Junos Space application deployment simpler by giving administrators a turnkey solution. You can power up a the JA1500 appliance, make required configuration changes, then start using the Junos Space application without concerning yourself with hardware and OS and application installation. (See Figure 1 on page 3).

Figure 1: Junos Space JA1500 Appliance

The JA1500 appliance allows administrators to migrate from a strategy of one large server in the corner, to distribute multiple servers based on load and geography. You can combine Junos Space appliances in clusters for high availability or increased throughput.

The JA1500 appliance ensures that consistent infrastructure is deployed across an organization, reducing complexity. The JA1500 appliance means that only one vendor—Juniper Networks—supports integrated components reducing complexity.

The administrator can also deploy and run the Junos Space application as a virtual appliance. The administrator can combine Junos Space appliances in clusters for high availabilityor increased throughput. The administratorcan create a fabric of Junos Space appliances, Junos Space virtual appliances, or a combination of both appliances and virtual appliances.

Understanding How Nodes Are Connected in a Fabric

Each Junos Space appliance (physical or virtual) that you install and configure is represented as a single node in the fabric. You can add nodes without disrupting the services that are running on the fabric. When you install and configure the first appliance, Junos Space automatically creates a fabric with one node. For each additional appliance you install and configure, you must add a node to logically represent the appliance in the fabric. Youadd nodes to the fabric from the Administration workspace in the Junos Space user interface. Each node that you add to the fabric increases the resource pool for the node functions to meet the scalability and availability requirements of your network. By default, Junos Space automatically enables node functionality across the nodes in the fabric to distribute workload.The nodes in the fabric work together to provide a virtualized resource pool for each of the node functions: load balancer, database, and application logic.

In a fabric comprising two or more nodes, Junos Space provides failover when a node functioning as the active server (load balancer server or database server) goes down. By default, Junos Space marks a particular node down and routes failover requests to the node that Junos Space designates as standby server. Junos Space uses a heartbeat mechanism to check whether the nodes in the fabric are running. When a node functioning as the active server fails (the appliance crashes or stops sending heartbeats), the node functioning as the standby server takes over all resources that were managed by the node functioning as active server. Nodes in a Junos Space fabric rely on IP multicast messagesto discover each other, thereforeensure that IP multicast packets are reachable among all nodes in the Junos Space fabric.

Documentation

To add, manage, and monitor the nodes in the fabric, a Junos Space user connects to a single Web IP address. The IP address of first (active) node and second (standby) node, and the Web (virtual) IP address must all be in the same subnet. The Web IP address must work on both the first and second node in the fabric. When both nodes are in same subnet, and the first (active) node goes down, the second (standby) node becomes the active node and packets continue to be directed from the router to the Junos Space Web IP address, and then to the second node. However, if the second (standby) node is configuredin a different subnet from the first (active) node, and the first node goes down, the second node becomes the active node, but because the Web IP address now points to a different subnet address, packets originally destined for first node will not be received by the second node.

NTP Time Source For Each JA1500 Appliance

To ensure consistent behavior among all nodes in a multinode fabric, each node’s time must be synchronized with every other node in the fabric. When you configure each Junos Space JA1500 appliance with an NTP server, you ensure that, if the first node (which is used to synchronize time for all nodes in the fabric) goes down, all other nodes in the fabric remain synchronized. To ensure this behavior, all nodes in a fabric must use the same external NTP source that you configure for the first appliance.

NOTE: By default, Junos Space translates time so that the time displayed in

the user interface corresponds to Junos Space server time, but is mapped to the local time zone of your client computer.

The default system clock for a JA1500 appliance may not be precise enough for some networks. To ensure time synchronization across all nodes in the fabric, Juniper strongly recommends that you use the following guidelines:

Chapter 1: Overview of the Junos Space JA1500 Appliance

•

Add an NTP server to the first virtual appliance during initial setup.

•

For each additional appliance, add the same NTP server that you specified for the first appliance.

Documentation

• Understanding How Nodes Are Connected in a Fabric on page 8

• Managing Nodes in the Fabric

Fabric Management Overview

You can deploy Junos Space appliances to create a fabric that provides the scalability and availability that your managed network requires as you add more devices, services, and users.

A Junos Space fabric comprises one or more IP-connected nodes. A node is a logical object that represents a single Junos Space JA1500 appliance or Junos Space virtual appliance, its operating system, and the Junos Space software that runs on the operating system. Each Junos Space appliance or virtual appliance that you install and configure is represented as a single node in the fabric. You can add nodes without disrupting the services that are running on the fabric. When you add nodes to the fabric, you can manage and monitor the nodes from the Administrationworkspace. To add, manage, and monitor

NOTE: You must add the NTP server before you add the first node to the

fabric from the user interface.

nodes in the fabric, a fabric administrator connects to a single virtual IP address. See

Figure 5 on page 10

Figure 5: AdministratorConnects to a Single Virtual IP Address to Manage Fabric Nodes

Single Node Functionality

When the fabric comprises a single appliance, all devices in the managed network connect to the appliance. When you install and configure the first appliance, Junos Space automatically creates a fabric with one node. By default, a fabric that consists of a single node provides complete Junos Space management functionality. The following node functions are enabled for the node:

•

Load Balancer— for processing HTTP requests from remote browsers and NBI clients

•

Database— for processing database requests (create, read, update, and delete operations)

•

Application Logic— for processing Junos Space service requests and Data Manipulation Language (DML) workload (device connectivity, device events, and logging)

NOTE: A fabric that comprises a single node provides no workload balancing

and no backup if the appliance goes down.

Page 25

Multinode Functionality

As your network expands with new devices, services, and users, you can add Junos Space appliances to handle the increased workload. When you install and configure the first appliance, Junos Space automatically creates a fabric with one node. For each additional appliance you install and configure, you must add a node to logically represent the appliance in the fabric. Each node that you add to the fabric increases the resource pool for the node functions to meet the scalability and availability requirements of your network. By default, Junos Space automatically enables node functionality across the nodes in the fabric to distribute workload. The nodes in the fabric work together to provide a virtualized resource pool for each of the node functions: load balancer, database, and application logic.

The Junos Space node functions distribute workload across operating nodes according to the following load-distribution rules:

•

Chapter 1: Overview of the Junos Space JA1500 Appliance

LoadBalancer—When a node that functions as the active load balancer server is down, all HTTP requests are automatically routed to the standby load balancer server that is running on a separate node.

•

Database— When a node that functions as the active database server is down, all database requests (create, read, update, and delete) are routed to the node that functions as the standby database server.

•

Application Logic— Device connections and user requests are distributed among the nodes, and device-related operations are routed to the node to which the device is connected.

Junos Space uses the following algorithm to ensure that the number of devices connected to a node does not exceed the threshold limit for each node:

Threshold Limit = [ (number of devices in database) / (number of nodes running) ] + 2

The following workflow describes how the node functions are enabled across the fabric as nodes are added:

•

First node: The load balancer, database, and application logic functions are enabled on the node. Each node function provides both scalability and high availability. Figure

6 on page 11 shows all functions enabled on a fabric comprising one node.

Figure 6: Functions Enabled on Fabric Containing One Node

Page 26

JA1500 Appliance User Guide

•

Second node: When a second node is added to the fabric, the first node functions as the active load balancer server and active database server, and the second node functions as the standby load balancer server and standby database server. The load balancer and application logic node functions provide scalability and high availability. The database node function on the second node provides high availability only. Figure

7 on page 12 shows the functions enabled on a fabric comprising two nodes.

Figure 7: Functions Enabled on Fabric Containing Two Nodes

•

Third and subsequent nodes: Only the application logic functionality is enabled on the third node to provide equal distribution of device connections and user requests across all nodes, and to route device-related operations to the node to which the device is connected. The application logic functionality provides both scalability and high availability. Figure 8 on page 12 shows the functions enabled on a fabric comprising three nodes.

Figure 8: Functions Enabled on Fabric Containing Three Nodes

NOTE: For the third node and each subsequent node added to the fabric,

only the application logic functionality is enabled.

Page 27

Node Function Availability

In a fabric comprising two or more nodes, Junos Space provides failover when a node functioning as the active server (load balancer server or database server) goes down. By default, Junos Space marks a particular node down and routes failover requests to the node that Junos Space designates as standby server. Junos Space uses a heartbeat mechanism to check whether the nodes in the fabric are running. When a node functioning as the active server fails (the appliance physically crashes or stops sending heartbeats), the node functioning as the standby server takes over all resources that were managed by the node functioning as the active server.

Fire Safety Requirements for the Junos Space JA1500 Appliance on page 24•

• Environmental Requirements for the Junos Space JA1500 Appliance on page 18

Fire Safety Requirements for the Junos Space JA1500 Appliance

In the event of a fire emergency involving switches and other network equipment, the safety of people is the primary concern. You should establish procedures for protecting people in the event of a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers.

In addition, you should establish procedures to protect your equipment in the event of a fire emergency.Juniper Networks products should be installed in an environment suitable for electronic equipment. We recommend that fire suppression equipment be available in the event of a fire in the vicinity of the equipment, and that all local fire, safety, and electrical codes and ordinances be observed when installing and operating your equipment.

Fire Suppression

In the event of an electrical hazard or an electrical fire, you should first turn power off to the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive fire retardants, to extinguish the fire.

Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide and Halotron™, are most effective for suppressing electrical fires. Type C fire extinguishers displace oxygen from the point of combustion to eliminate the fire. For extinguishing fire on or around equipment that draws air from the environment for cooling, you should use this type of inert oxygen displacement extinguisher instead of an extinguisher that leaves residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers). The primary ingredient in these fire extinguishers is monoammonium

Page 39

Chapter 3: Safety and Compliance for the Junos Space JA1500 Appliance

phosphate,which is very sticky and difficult to clean. In addition, in the presence of minute amounts of moisture, monoammonium phosphate can become highly corrosive and corrodes most metals.

Any equipment in a room in which a chemical fire extinguisher has been discharged is subject to premature failure and unreliable operation. The equipment is considered to be irreparably damaged.

NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher

to control a fire at or near a Juniper Networks appliance. If a dry chemical fire extinguisher is used, the unit is no longer eligible for coverage under a service agreement.

We recommend that you dispose of any irreparably damaged equipment in an environmentally responsible manner.

Booting and Configuring the Junos Space JA1500 Appliance from a USB Drive

This procedure shows you how to reset a Junos Space appliance to its factory settings by using a standard USB 2.0 drive.

This process has three main steps:

1. Copying an ISO image onto the key

2. Ensuring that the appliance’s basic input/output system (BIOS) boots from the key

instead of the disk

3. Running the reinstallation procedure

To reset an appliance to the factory settings from a USB drive:

1. Plug the USB drive into the USB port of a device, such as a laptop or PC, that is

connected to the Internet.

NOTE: For images up to Release 11.2, you can use a USB drive with 2 GB

of free space. However, for Releases 11.4 and later, you must use a USB drive with at least 4 GB of free space.

2. Using a Web browser, navigate to the Juniper Networks Junos Space software

download site (http://www.juniper.net/support/products/space/), and click Image for

hardware Appliance to download the Junos Space USB bootable image.

The name of the downloaded image will be space-< version >.< spinnumber >.img. For example, space-11.1R1.1.img

3. Convert and copy the ISO image to the USB drive.

Page 49

Chapter 4: Installing the Junos Space JA1500 Appliance

You can copy the ISO image to the USB drive in two ways:

•

Using Win32 Disk Imager software (for Windows users)

To create a bootable USB drive using the Win32 Disk Imager software, follow these steps:

a. Open the Win32. Disk Imager software to copy the Junos Space ISO image file

to your USB drive. The Win32 Disk Imager dialog box appears.

(You can download the Win32 Disk Imager software for free from

https://launchpad.net/win32-image-writer .)

b. Click the browse icon and select the image file that you want to copy to the USB

drive.

c. Verify that the device drive letter matches the chosen USB drive, and click Write.

After creating the USB drive, you need to set up the device (laptop or PC) and Junos Space appliance to accept the USB drive as the reinstall media. For this, the BIOS menu of the appliance needs to be modified. You can modify the BIOS menu by creating a serial connection between the device (laptop or PC) and the Junos Space appliance. Togain access to the BIOS menu, you must use a terminal application (such as Putty, Hyperterm, or SecureCRT) to send a DEL character to the Junos Space appliance as soon as it powers on.

The terminal application maps every keyboard key to a code that it sends through the serial cable. Typically, pressing the Delete key on a PC keyboard does not send a DEL character.

To ensure that the terminal application maps a key to the DEL character, go to the settings dialog box of the application and select the Backspace Key sends

DEL option. After you make this modification, you must ensure that the connection

is opened with the typical serial parameters of 9600, 8, none, 1, and none.

•

Using the dd program in Linux

You can also use Linux distributions to create a bootable USB drive. You do not need a PC for this procedure.

To create a bootable USB drive using Linux distributions:

a. While you can use any of the available conversion tools, we recommend using

the dd program in Linux to convert the ISO image.

In a CLI window, enter the following command at the CLI prompt to convert and copy the ISO image:

dd if= space-< version >.< spinnumber >.img of=/dev/sdb

where

space-< version >.< spinnumber >.img is the name of the downloaded image. /dev/sdb is the name of the device drive into which your USB drive is plugged..

b. Press the Enter key to copy the ISO image to the USB drive.

Page 50

JA1500 Appliance User Guide

4. After you copy the ISO image to the USB drive, remove the USB drive from the device

and plug it into the USB port of the Junos Space JA1500 appliance.

5. Power on the appliance. The boot menu appears.

6. After about one minute, the BIOS menu appears.

NOTE: If the hard disk LEDs begin to flash at this point for more than a

few seconds, the appliance is booting from disk instead of the USB drive and is not loading the BIOS menu.

7. Ensure that the USB boot is at the top of the appliance boot priority order.

By default, the boot order in the BIOS of the appliance prevents it from booting from a USB drive. However,you can access the menu and change the boot order by sending the DEL character three times as soon as you power on the appliance.

Press the DEL key three times as soon as the appliance powers on. The BIOS setup appears and displays the appliance boot priority order:

Boot priority order: 1: USB KEY: CBM USB 2.0-(USB 2.0) 2: PCI SCSI: ASR-5405 PCI-E RAID 3: PCI BEV: IBA GE Slot 0B00 v1240 4: USB CDROM 5: ALL USB KEY 6: All USB CDROM 7: CF Card: 8: SATA Port 1:

If USB KEY:CBM USB 2.0- (USB 2.0) is not at the top of the list, use the down arrow to select it and the <+> key to move it to the top of the list. Press the F10 key to save your changes and exit the BIOS setup.

8. After you have confirmed the BIOS setting, power off the appliance.

9. Power on the appliance again. The boot prompt displays the following menu:

To enter rescue mode, type rescue-serial < ENTER > or rescue-kvm < ENTER >

To boot from local type: local < ENTER >

To reinstall type: reinstall < ENTER > boot:

Type reinstall and press the Enter key at the boot prompt to install the ISO image from the USB drive.

If no input is provided, the appliance boots from the local disk by default.

After completing the installation, the appliance powers down. The reinstallation process should take 30 to 60 minutes

Page 51

Chapter 4: Installing the Junos Space JA1500 Appliance

WARNING: This procedure overwrites your hard disk drive with a new

factory default Junos Space installation. No trace of the previous installation or configuration shall remain. If you do not want to erase your system, power off the device immediately.

10. The next time you power on the appliance, it boots with the Junos Space version you

have selected, and eventually prompts you for the default username (super) and password (juniper123).

NOTE: Do not remove the USB drive until the reinstallation procedure is

complete and the appliance is powered off.

Understanding How Junos Space Uses Ethernet Interfaces eth0 and eth3

Junos Space is designed to perform best using only eth0 if the managed devices are routable, using in-bound management. Use eth3 for a device management subnet if the managed devices are non-routable or on an out-of-band management subnet.

Table 10 on page 44 describes how Junos Space interfaces intentionally function:

Table 10: How Junos Space IP Addresses Function

Function/Interface

SSH and device management if eth3 is not configured (node IP)eth0

GUI interface with an instance of JBOSS running (GUI)eth0:0

Not supportedeth1

Not supportedeth2

eth3

Device management when managed devices are on a subnet and not reachable by way of eth0.

Junos Space uses eth0 and eth3 interfaces as follows:

•

Secure Shell Daemon (sshd) is listening on all IP addresses.

•

The web interface is only on the VIP, the same subnet as eth0.

•

Device management, outbound (discover) and inbound (post-discovery), including syslog and DMI, should be eth3, or eth0 if eth3 is not configured.

Adding a Node in the Fabric

You can deploy one or more Junos Space appliances or virtual appliances to create a scalable fabric. As the number of devices on your network expands, you can add nodes to the fabric to manage the increased workload. Each Junos Space appliance and virtual appliance that runs the complete Junos Space software is represented as a single node in the fabric. By default, the Junos Space fabric contains a single node that provides complete Junos Space management functionality. Junos Space automatically adds the first node to the fabric and uses the logical node name that you assign to the appliance or virtual appliance when you configure the first appliance (node) in a cluster (fabric). For each additional appliance or virtual appliance you deploy, you must add the node in Junos Space to represent the appliance or virtual appliance in the fabric.

Before you add a node to the fabric, you must ensure the following:

•

The new node must be configured to be added to an existing cluster. See Configuring

an Appliance to Add to an Existing Cluster for more details.

•

The ETH0 IP address on the first and second nodes and the virtual IP (VIP) address for the fabric must be in the same subnet.

•

You must be able to route multicast packets through all nodes in the fabric.

•

You must configure the same Network Time Protocol (NTP) servers on all nodes in the fabric.

•

You must ensure that all nodes are running the same software release version.

•

If the new node is a virtual appliance, you must ensure that the first and second nodes are hosted on two separate VMware ESX servers to ensure failover support.

•

Adding a Node on page 53

You can add one or more nodes to the existing Junos Space fabric, but you can add only one node at a time.

To add a node to the Junos Space fabric:

1. From the taskbar, select the Administration workspace.

2. From the taskbar, select the Manage Fabric icon.

3. From the taskbar, select the Add Fabric Node task.

The Add Fabric Node screen appears.

4. In the Name field, enter a name for the node.

5. In the IP address field, enter the IP address of the Junos Space appliance or virtual

appliance.

6. Schedule the Add Fabric Node operation:

•

Clear the Schedule at a later time check box (the default) to initiate the add node operation when you complete step 7 of this procedure.

•

Select the Schedule at a later time check box to specify a later start date and time for the add node operation.

NOTE: The selected time in the scheduler corresponds to Junos Space

server time but is mapped to the local time zone of the client computer.

7. Click Add to add the node to the fabric.

Page 68

JA1500 Appliance User Guide

The node is added to the fabric and appears in the Junos Space user interface and database. When you add a node, the node functions are automatically assigned by Junos Space. By default, the first and second nodes added to a fabric perform all the following functions:

•

Database— for processing database requests (create, read, update, and delete operations)

•

Load Balancer— for processing HTTP requests from remote browsers and NBI clients

•

Application Logic— for processing back-end business logic (Junos Space service requests) and data manipulation language (DML) workload (device connectivity, device events, and logging)

By default, the third node, and all subsequent nodes, added to a fabric perform only the Application Logic function.
