Each row in each table except for the last row of the last table, shows a parameter and value. Should you need to change this value, you would alter the value on the right, then click the corresponding update button on the left. It works the same way for changing every parameter.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E Stripes Required in Memory before Read Ahead Allowed: This is the amount of sequential data that must be read in order to trigger the read-ahead cache above. The default value, 24, (using the same stripe value as above 128KB), means that the client must request 3MB of sequential data in order to activate the cache.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E lower gives up some of the cache to the non-real-time users. It's almost the opposite of above. Note that this setting applies globally to all real-time users. Max Data Rate of Non-Real-Time Requests (MB/SEC) 0 for no limit: This allows you to limit the bandwidth of non-real-time users in megabytes per second. It is used to free up bandwidth for real-time users as well.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E The Display button on the bottom of the table, displays the diagnostic message log. Note that it is important that this function only be used when directed to do so, and it must be disabled when not in use, otherwise it would fill up the boot drive.

The upper right of each shows information pertaining to the current minute. The upper left shows the previous minute. The middle right shows the current hour, the middle left shows the last hour. The lower right shows the current day, and lower left shows the last day.

Vertically, it is showing the number of commands executed. Horizontally, it is how long each command took during that time period.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E The third set of graphs shows transfer sizes: This set of charts is showing the number of commands, versus the transfer size at the bottom. If you use only one application to access the array, what you would like to see here is a single bar, as far to the right as possible. This indicates that the array did a lot of large transfers, which were all equal in size.

It's important to note that the slot number does not necessarily correspond to the logical position of a drive within a RAID. For example, you could have a chassis with 24 slots, but have (2) 12-drive RAIDs defined, each of which, with a drive 0, 1, 2, etc.

The fans will operate at approximately 50% of their speed when the temperature is low, and at full speed if the temperature becomes too great. Several things can happen with the fans: If the bearings break down inside, they will stop spinning.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E Air Intakes/Exhaust: These should be periodically cleaned, as their blockage could generate unnecessary heat inside the array. Rack Mounting: On many of the chassis we’ve used, there are problems associated with the weight of the unit when used in a Rack configuration. The rack mounting system typically starts at the chassis itself, with a series of tangs which are punched out of the metal.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E if there’s rust on the outside, electronic components on the inside could also be rusting – and those can’t be cleaned with the Royal Jelly. 4.8 Motherboard problems Connectors: As with the plugs which plug into them, many connectors can be damaged – especially SATA connectors on the motherboard.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E SATA/SAS (On-board): We do use the on-board SAS/SATA controller(s) for our products. Some of the motherboards we use have up to 3 independent controllers – each different brands/models. Typically, on-board SATA is handled by the Intel ESB2 controller. If it fails, the array won’t boot. Some other systems use Intel ICH-9R or ICH-10R RAID controllers.
G A L A X Y ® 4.9 A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E Drive Backplane problems In general, there’s two kinds of drive backplanes we use. One is a discreet backplane – the other is a SAS-switched backplane. Both types of backplanes have an SES2 enclosure management chip, which operates the LEDs and controls and monitors voltages, temperatures, and fans on the backplane itself. The way this chip connects to the host is different, however.

The 8 other LEDs show communication between the drives and the card. If one doesn’t light, then chances are there is no communication on that port. Rechecking cables first is always the best thing. One other note: These cards typically use the LSI 1068e chip. This chip supports a maximum of about 192 devices.

The amount of problems that is possible with these cables is somewhat astronomical compared with other cables.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E Going clockwise from the upper left, you have to have a RAID in order to create a LUN. The user and Initiator are optional, however if there are any defined, the user you are trying to communicate with must also be set up as a user and given read only or read/write access to the LUN.

If not, there might be a bad cable, SFP, or HBA. 4.17 Using IPMI to diagnose problems Some NumaRAID arrays are equipped with an IPMI card (short for Intelligent Peripheral Management Interface). This card or on-board chip is literally a second computer, but is very small.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E The main IPMI window should appear as follows: You can get into the IPMI card at any time. If you left-click on Power Down, as in the image above, and the array is powered on, you won't be able to stop it – it will be off as if the power switch itself was pressed. Also, if you left-click on the Reset button, the array will reboot as if you actually hit the reset button on the front.
G A L A X Y ® A U R O U R A L S C O N F I G U R A T I O N A N D S Y S T E M I N T E G R A T I O N G U I D E Monitor Sensors will bring up the following window: You are interested in the items which are red on the left. In the example above, four of the fans are in red – this was normal for this particular model, where there are no fans connected to connectors 4 through 7. On this system, there were (5) fans – one each on connectors 1 through 3 and connectors 7 and 8.
