Chapter 1: Introduction 1.1 About the QOS 8-Bay The QOS is a standalone storage array, part of a file-‐based workflow involving one or more users and a single centralized storage system. The extraordinary power and versa-‐ tility of the QOS is one of the key features of this product.
1.4 Boot Up and Shut Down Some models of the QOS 8-‐Bay have a 0/1 power switch that sends power to the power supply. This has to be turned on before the power button is pressed to supply power and after the unit is booted down to fully power down. To begin using the QOS press the power button on the rear.
1.6 Backpane The backside of the QOS hosts all the adapters, Ethernet, Fibre Channel, 10GigE, power, diagnostic VGA and USB cables. Data ports such as Ethernet and Fibre Channel have green activity lights that indicate a healthy connection.
panel and will be displayed as ‘BAD’ in the NumaRAID software controller’s RAID Details menu. The system will continue to process read/write requests using parity information from the other seven drives.
fore inserting it. To remove a drive, simply open the front panel with the key, look at the red ‘failed’ indicator light and follow it up to the failed drive, unscrew the mounting screw, and gently slide it out and place it into a static-‐free bag.
192.168.2.101 range is 192.168.2). The fourth number of the IP cannot be the same as the server’s or any of the other attached clients. Use the Subnet Mask 255.255.255.0.
Note: If you cannot reach this page, check the IP for mistakes and make sure you are connected to the correct port on the QOS. You can also check that your client network settings have been properly configured to the same IP range as the server (see User Network Configuration).
data before it is written to the drives and achieves faster speeds by using memory con-‐ nected directly to the motherboard.
status on this page. This is the only page that contains information about the state of the drives in the RAID. The Slots menu only indicates the physical health of the hard drives. 2.4 LUN Creation Logical Unit Numbers are logical storage used as the building blocks of a RAID set.
2.5 Scan & See Performance Stats The Scan & See Performance Stats button located to the left of the RAID Name on the RAID Details page allows you to gather test information by performing read/write tests on the drives in the QOS 8-‐Bay RAID.
2.6 Configurations and Log Files From the main NumaRAID menu Configurations and Log Files displays diagnostic infor-‐ mation, creates logs for technical support, and transfers and archives config files. The Config file stores information about the state of a RAID set.
to a saved text file using the First or Last selector followed by the number of entries re-‐ quired. Control Trace can start, stop, or reset a Trace display in progress. The Trace details page can be used to check for bad sectors, drive read/write errors, and stuck processes.
Dirty: Indicates the existence of Dirty segments in the cache (‘Dirty’ refers to a cached file that is inconsistent with the server). This value should be 0 for all commands. Status: Either displays 0 or 1 to inform the user if the command was successful (0) or if it failed (1).
2 Transfer Length Graph shows Transfer length (Y) against Entry Number (X). In this case as all transfers were 1024 Bytes so the graph is a straight line. 3 Cache Access time shows the amount of time allowed to the Cache (Y) against the Entry Number (X). This graph is likely to be non-‐linear.
destructively. At the top of the page there is a list of the current users, and below that a list of ‘Real Time Users.’ A Real Time User is a user that requires higher priority to the bandwidth. You can select from the dropdown list who will be promoted to a real time user.
2.8 Parameters The parameters menu is accessible from the main NumaRAID menu and sets out the overall NumaRAID settings that will apply universally. The following settings are availa-‐ ble: Maximum Read Ahead Distance in 128k Stripes: When you playback video for exam-‐ ple, you are essentially doing one large sequential read.
quential data that must be read in order to trigger the read-‐ahead cache above. The de-‐ fault 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.
Percent of Cache Available to Non-‐Real-‐Time Writes: This applies to the real-‐time us-‐ ers. You can actually dial-‐down the cache for writing for non-‐real-‐time users. This value is a percentage. The default value of 50, indicates that real-‐time users only get a maxi-‐ mum of 50% of the cache.
Internal Diagnostic Message Level: More explicitly, this value determines what you want the internal diagnostics to log. Here are the values and what they do: Disabled: Do not log anything. Requests: Only log read/write requests. State Started: Only log state engine starts. State Ended: Only log state engine completions.
2.10 Datarate Graphs: 1 2 3 1 Real Time Data Rate of the chosen device (Y) against time in seconds (X) recorded last minute and this minute. A useful tool to use during long copy and paste opera-‐ tions to test the speeds of the transfer at different points in time.
1 2 3 1 Number of commands (Y) within a specific response time range (X) recorded last minute and this minute. A useful tool for analyzing the strength of the NumaRAID application and QOS hardware.
1 2 3 1 Number of commands (Y) against specific transfer size rangers in KB (Y) recorded last minute and this minute. If the QOS has heavy I/O traffic, this feature will help get a sense of the fluctuations in load over time.
2.11 Slot Details SLOT Details – accessible from the main NumaRAID menu – offers a way to check on the health status of drives in the QOS 8-‐Bay system and read detailed information about drives from firmware with SMART (Self-‐Monitoring, Analysis, and Reporting Technology).
2.12 SMART Info Device: Shows the manufacturer, model number, and firmware revision of the de-‐ vice. Serial Number: Is the serial number: Note that the actual serial number is just the rightmost 8 characters. The rest of the string is a manufacturer-‐unique ID. Device Type: Shows the type of the de-‐ vice.
the caching is on the drive. If the computer (initiator) requested the same block twice, and it happened to be in the cache of the drive, then the drive would not have to read it again from the disks, so in general, this number would be the same or always higher than the Blocks sent to the Initiator.
2.13 Sensors The Sensors menu shows real time feedback about different hardware components in the system such as the CPU, motherboard power output, and CMOS battery. Values are up-‐ dated each time this page is loaded.
On the same page, NumaRAID Fibre Channel Ports presents a list of the ports on the QOS 8’s Fibre Channel HBA. The Link Status and Link Speed are useful for troubleshooting Fi-‐ bre Channel connection problems.
turn DHCP on and off using the space bar. When finished navigate to the OK button and hit Enter. Warning: If you plan to connect two shared clients into the two different Ethernet Ports, put the two ports on different IP Ranges (Ex. 10.0.1.101 and 10.0.2.101) in order to avoid IP conflicts.
Step 1: Click on the Fibre Channel LUN in Disk Utility. Note: Make sure you have the correct drive selected so that you don’t wipe out any other data unintentionally.
Step 3: Select 1 Partition from the Volume Scheme drop down menu. Step 4: Name the Partition as desired, and set the format to Mac OS Extended (Jour-‐ naled). Click Apply to apply the changes. Warning: This will erase all data on the LUN. 4.
Step 1: Right click on My Computer and select Manage. Step 2: From the options on the left hand size, choose Disk Management, in 64-‐Bit Oper-‐ ating Systems, the Initialize Disk pop-‐up will appear. Warning: Proceeding from here will erase all data on the LUN.
Step 3: If the Initialize Disk window comes up, choose GPT (GUID Partition Table) from the Partition Style selection box. Step 4: Right click on the LUN in Disk Management and click New Simple Volume QOS 8-Bay User Manual QOS Server is a subsidary of Ocean Tides Productions Ltd.
Step 5: The New Simple Volume Wizard will come up for configuring the new Volume. The first menu will prompt you to Specify a Volume Size. Use the default full size and click ‘Next.
Step 7: Click finish to complete the installation. The new NTFS volume should be ready to be use. Chapter 5: Contact Info & Technical Support When you purchase a QOS Series product we provide additional technical support to go with it.
