Preface Document Overview This document provides operating procedures for the RamSan-210. It covers installation, management, and troubling shooting issues. Conventions The following textual conventions are used in this document: Select Ethernet Setup lunconfig Front panel button descriptions Front panel text (menu items) Management port (serial/telnet) commands and text. -
Page 7: Chapter 1 - Introduction
The RamSan-210 can be connected via Fibre Channel to host servers, NAS filers or to storage network switches and hubs. If you have specific questions about compatibility, please see or contact Texas Memory Systems directly. The RamSan-210 can be used in a variety of applications. If your application is slowed down by hard disk drives, there is a good chance that the RamSan-210 can speed it up. -
Page 8: Power Requirements
Power Requirements The RamSan-210 requires 150 watts of power for a fully loaded system. The RamSan- 210 includes two power supplies. Only one power supply is needed to run the system. The power supplies are auto-ranging (they will accept either 110 or 220 power). Each power supply is connected to an internal battery. - Page 9 Statistically, most applications have 80% reads and 20% writes. For systems that are write intensive, please contact Texas Memory Systems to discuss configuration alternatives. The RamSan-210 with two FC32 Fibre Channel controllers should be able to provide very close to 400MB/second of read performance.

Page 12: Rack Mounting
Rack Mounting The RamSan-210 is a 2U rack-mountable system. The system is shipped with the slides and equipment needed to install it into a standard 19” rack. Connecting the Fibre Channel Ports After you have inspected the system and properly mounted it, connect the Fibre Channel ports on the RamSan-210 to either your server or to a Fibre Channel switch. - Page 13 one without any interruption in Fibre Channel service. However, if external power is completely lost, all Fibre Channel ports will go into a standby mode after a short user- defined timeout period because the system will power off. Warning: Do not remove both power supplies from the system at the same time. This will cause system failure since the internal batteries require that at least 1 power supply be present in the system at all times.
-
Page 14: Turning On The System
Turning on the System The RamSan-210 will automatically power on when power is connected to the system. The only time the system will not automatically power on is when a user has initiated a Manual Shutdown of the system. In the event this has happened, it is necessary to press the top button on either power supply. -
Page 15: Figure 3-2 Ramsan-210 Front Panel
Chapter 3 – Using the Front Panel Overview The front panel for the RamSan-210 allows you to inspect the state of the system, change the method of IP address assignment, and shutdown the system. Four buttons located to the left of the panel are used to make selections. Figure 4.1 is a picture of the front of the system. -
Page 16: Menu System Layout
Menu System Layout The front panel menu system is as follows: RS-210 Main Menu Ethernet Setup § Set IP Config § Static § IP § Subnet Mask § Gateway § DHCP § BOOTP § RARP § None § No Change (Exit) §... -
Page 17: Manual Shutdown
After selecting “Set IP Config”, you may use the arrow buttons to cycle though “Static IP”, “DHCP”, “BOOTP”, “RARP”, “None”, and “No Change”. Talk to your system administrator for the proper IP assignment type. Use the “Select” button to select the desired method of IP assignment. If you did not choose “Static IP” you are asked to confirm the selection with the “... -

display will now indicate that the system is powering off. This will typically take between 5 and 15 seconds to complete. As a reminder, in order to turn the RamSan-210 back on after a manual shutdown it is necessary to press the top button on either power supply. System Monitoring When the menu on the front panel is not in use, it is possible to monitor various aspects of the system. - Page 19 o “*FAIL*”. This indicated that a System Failure has been detected. Possible failures include: – Front or rear fan trays have a failed fan – Power supply failed – One or both batteries have failed – System overheated – One or both disks have failed In the case of either System Warnings or Failures, the front panel display will alternate between displaying status information and Warning/Failure messages every 10 seconds.

Page 20: Chapter 4 The Management Control Port (Mcp)
Chapter 4 The Management Control Port (MCP) Connecting to the MCP The management port on the RamSan-210 allows you to manage, configure, and monitor system behavior. This includes obtaining status information about internal hardware, configuring the LUNs, and obtaining data rates of the system. You may connect to the management port using either a DB-9 serial cable or an RJ-45 Ethernet cable. -
Page 21: Mcp Commands
MCP Commands 4.5.1 EXIT The exit command is used to close a monitor session. The “QUIT” command also performs the same action. 4.5.2 HELP The “HELP” command provides a brief online description of each command that is available. Commands that require parameters are listed with the “<parameters>” as options. - Page 22 IP Address Netmask Select option: 1. Change IP assignment mode 2. Change hostname S. Save changes, restart the network, and exit Q. Cancel (No changes) Enter selection: To change the IP assignment mode enter “1”. This will present the following screen: ** Ethernet configuration utility ** Current IP assignment: RARP Select option:...

To exit the IP configuration utility, select “S” to save the changes you have made. The network will be reconfigured to use the new Ethernet settings you have chosen. To discard any changes you have made, use the “Q” option. 4.5.6 LUNCONFIG This command is a memory-partitioning tool that allows the administrator to configure... -
Page 24: Performance
The password feature is automatically bypassed when logging in on the serial console. This feature allows a system administrator access to the RamSan-210 if the password is forgotten or lost. 4.5.9 PERFORMANCE The “PERFORMANCE” command may be used to view the bandwidth of each port. The monitor shows the average bandwidth of each port over a period of one second. -

Page 26: Chapter 5- Hot Swap Components
Hot Swapping Power Supplies The RamSan-210 includes two power supplies. The system only requires one functioning power supply to run. Texas Memory Systems has taken special care to enclose the RamSan-210 power supplies in a protective case in order to minimize the electrical risks for users. -
Page 27: Hot Swapping Disk Drives
Hot Swapping Disk Drives The RamSan-210 includes two mirrored hard disk drives. The system can operate with two disks operational, one disk operational or no disks operational. Normal operation mirrors writes to both disk drives. If a single disk drive fails, the system will continue to write to the available disk drive. At this point, it is desirable to replace the malfunctioning disk with a new disk drive. - Page 28 The following steps should be performed to hot swap a fan block: 1. Slide the latch on the fans to the left and simultaneously pull firmly on the fan handle. The unit will slide out from the chassis. Use caution to avoid hitting the spinning fan blades once removed.

Page 29: Chapter 6 - Batteries
Chapter 6 – Batteries The RamSan-210 is equipped with two redundant one-hour Lithium Ion batteries. The batteries are designed to support the RamSan’s operational modes. Specifically, if external power to the RamSan-210 is lost, the system will continue to function running on the internal batteries. -
