JMR Storage Manager is a standalone utility that allows for the management of
JMR storage systems over an IP network. It is an out-of-band management
solution that can be used to configure, monitor and maintain RAID
configurations, enclosure and sub-enclosure elements, such as controllers,
batteries, alarms, fans, temperature sensors, power supplies, and disk drives (see
Figure 1). The Global View on the lower section of the window allows you to
click on the system you want to manage.
Figure 1. Main Application Window
JMR Storage Manager also manages the status of the controller and the overall
storage system configuration. JMR Storage Manager may also be used to define
and manage policies of the storage system, upgrade firmware, and setup user
notification. Revision 1.20 also supports JMR controllers with optional Snapshot
functionality.
For example, you can use JMR Storage Manager to create an array configuration
using RAID Levels 0, 1, or 5 etc. The basic functions include the following:
create/delete arrays, expand capacity of the arrays, assign global or dedicated hot-
spares, create/delete logical volumes, increase the size of logical volumes, map
volumes to specific servers, and assign a LUN (Logical Unit Number) to that
map. Management functions include the following: policies, view the event log
through the controller, notification by email, background jobs, initialize the disk
drives to create an array, initialize a rebuild, configure the system, configure the
controller, and download firmware. JMR Storage Manager supports RAID Levels
0, 1, 3, 5, 6, 10, 30, 50, 60 and Snapshot.
JMR Storage Manager may be used to manage a single storage system or multiple
storage systems over the network.

1. Introduction

The target audience is a system administrator with knowledge of IPadministration
and Storage Area Network (SAN) administration who will have the authority to
design the array configurations using the JMR Storage Manager software.
RAID Levels
Each RAID level provides a unique storage system solution ranging from fast
read/write, mirroring with 100 per cent redundancy, distributed parity, and layered
RAID configurations.
The following is a brief list of the RAID levels supported by JMR Storage
Manager controller.
RAID 0
Provides high I/O performance by striping (distributing) data across multiple
spindles; however, it does not provide fault tolerance.
RAID 1
Provides excellent fault tolerance through disk mirroring with improved read
performance and single spindle write performance, ideal for mission critical
database applications.
RAID 3
Provides high read performance, good write performance, and single spindle fault
tolerance for video applications.
RAID 5
Provides single drive failure protection with excellent read performance by
striping data and parity across multiple spindles, suitable for varied applications
requiring fault tolerance.
RAID 6
Provides double drive failure protection with excellent read performance by
striping data and dual parity across multiple spindles. Slightly less efficient
storage than RAID 5 and slightly slower write performance as two additional
parities must be written.
RAID 10
Provides striping of mirrors to improve read performance over RAID 1 and can
tolerate up to half of the spindles failing.
RAID 30
Improves RAID 3 read and write performance by striping multiple RAID 3 sets
and can selectively tolerate up to two spindle failures.
RAID 50
Improves RAID 5 read and write performance by striping multiple RAID 5 sets
and can selectively tolerate up to two spindle failures.

RAID 60
Improves RAID 6 read and write performance by striping multiple RAID 6 sets
and can selectively tolerate over two spindle failures.

Overview: Main Application Window–Three Panel
Divisions
In addition to the six basic regions of the Application Window, it is also divided
into three panels containing special characteristics, which are described below
(see Figure 8). The Logical Configuration Panel -- displays the system root,
RAID Sets, arrays, logical volumes, and snapshot volumes that are configured in
the system. The logical devices are arranged in a tree structure with the System
Icon as the root node, represented with a globe icon at the top.
Figure 8. Application Window – Three Panel Groups
Rolling the mouse over any of the icons will cause a tool tip to be displayed.
Right clicking a device icon will cause a drop menu to appear that provides a
number of operational options that may be performed on the selected item.
The Physical Elements Panel -- displays the representation of the enclosure(s),
the drives that are contained in them, and other enclosure elements such as
controllers, batteries, alarms, fans, temperature sensors, and power supplies.
When there are multiple enclosures (shelves), the main enclosure is always
shown as the top shelf. The Global View Panel -- displays the systems connected
in your configuration..

This tutorial section provides several mini tutorials on how to perform the most
common operations of the JMR Storage Manager. Each tutorial describes the
basic steps needed to complete the operation. Screen captures are combined with
the step-by-step descriptions to give you a visual aid of how to use the JMR
Storage Manager software. Additional detailed information is covered in the
Reference section, Chapter 4, later in this manual. Please read the note and follow
the instructions below as you begin to setup your system and before you build the
first array set.
NOTE: To avoid SMTP email notification problems with multiple systems, it is
recommended to develop the practice to change the default host name each time
you setup a new system. This is easily done through the Configuration Ethernet
Settings.
Click on the Controller Configuration icon Then click on the Network tab and
Configure Ethernet Settings button to reach the Properties window. Click on the
Modify Properties box and enter a unique host name. Click on Apply to save and
affect the changes. For complete details, please see Network under Configure
Controller Settings in the Reference section, Chapter 4.
The tutorials covered in this section are:
• Creating an Array
• Creating a Logical Volume
• LUN Mapping/Masking to a Host
• Assigning a Global Hot-Spare
• Online Capacity Expansion
• Increasing the Size of a Logical Volume
Creating an Array
An array configuration is a grouping of drives that are configured with a RAID
level as well as other properties. Creating the array is the first step in setting up
your storage system. For detailed instructions on two other methods to create an
array (using the menu bar or the array icon) and other array activity, please see
Array Options in the Reference section, Chapter 4.
STEP 1
3. Tutorial
Click on the Create Array button in the tool bar (see Figure 9) to
launch the Create Array wizard. Using the window on the next page,
you can create your array configuration (see Figure 10).

Figure 9. Create Array Button with Arrow Tip
Cache Settings
Enable Read Cache and Enable Write Back Cache are also automatically
engaged, which also may be disabled. Subsets of the cache options are: Disable
on Partner Controller Fault, Disable on Battery Fault, or Disable when Array
Degraded. Please see the note below and refer to the create array window (see
Figure 10). For best performance, it is recommended to enable all three options
when applicable. For additional information on the above items, refer to Cache
Settings under Array Options in the Reference section, Chapter 4.
NOTE: Enable (checkmark the box) the Disable on Partner Controller Fault
only when a dual controller is installed in your system.

First, click on the RAID level you want, in this example, RAID 6 was
chosen. There are several default values chosen by the Create Array
Wizard, which you may change as needed. For example, the Initialize
option has been selected, which will run in the background upon creation
of the array. While initializing, the array is available for use. There are
also several variations of cache settings, which are discussed below.

Click Next to proceed to the second Create Array screen, which provides
you a list of available member drives that may be used in the new
configuration (see Figure 11). Next to the column for the member drives,
there is a column for spares, which is how you assign one or more
dedicated spares while you are creating the array.
Choose the member drives for the array. In the Member column, you will
find that the wizard has auto-selected a minimal set of drives that will be
used in the new array. However, you may select additional or different
drive members by clicking on the respective check boxes in the Member
column. You may deselect drives by clicking on the checked box.

Figure 11. Custom Select Drives for an Array
NOTE: At this time, you may assign a dedicated hot-spare by clicking on an
available drive in the spare column, which will ensure an auto rebuild.
When working with RAID 6 or RAID 60, it is recommended that you create two
spares (dedicated or global) to ensure a complete auto rebuild (drives will be
rebuilt one at a time). Otherwise, you will need to use the manual rebuild
option. For more information, please see the entire sections, Assigning a
Dedicated Hot-Spare and Manually Rebuilding an Array in the Reference
section, Chapter 4.

STEP 4
This summary allows you to review the details of the array and the selected
member drives. If you want to modify any of the options, you may click Previous
to go back to a previous configuration page. When you are satisfied with the array
configuration, click Finish to commit the configuration.
