Connectivity and Interfaces Overview

The Memory Array contains two types of interfaces:

• Management Interfaces which allow access to the command line interface (CLI) for system configuration.

• Storage Interfaces which allow connection to a host computer or Memory Gateway for data transfer.

VMA-series Memory Array Installation and Service Guide

HP-AM456-9002A Rev 01

Page 29

Connectivity and Interfaces Overview

Refer to Figure 1.2 for interface locations.

Management Interfaces

Access to the system command line interface (CLI) is available through the following interfaces:

• DB-9 Serial Debug Interface—Opens the CLI on the system.

• Ethernet Interface—Opens the CLI on the system via Telnet or Secure Shell

(SSH).

See Connecting the Serial Cable on page 50 and Connecting the Ethernet Cable on page 51 for information.

Storage Interfaces

A single Memory Array may be configured for:

• Direct Attach via PCIe

• SAN attach via Fibre Channel or iSCSI (vSHARE)

Note: System configuration may be changed at any time.

The base platform supports a single PCIe x8 Gen1 (default) interface or dual PCIe x4 Gen2 (option) interfaces that can directly connect to a host computer (via a PCIe driver) or to a Memory Gateway. The optional memory gateways provide specific network interfaces and functions such as SAN block storage or NFS caching.

Note: The VMA-series Memory Array does not currently support dual PCIe

connections.

PCIe Direct Attach

PCIe provides the lowest latency and highest bandwidth connectivity to the Memory Array which supports eight lanes of PCIe Gen1 connectivity (20 Gbit/s line rate). The PCIe connection can go to a single host (PCIe x8) for maximum bandwidth or two hosts (PCIe x4 each) for reliability. See Connecting the PCIe

Cable to the Memory Array on page 46 for more information.

HP-AM456-9002A Rev 01

Where dual PCIe x4 interfaces are required, a special firmware image is loaded onto the Memory Array. Similarly, the Memory Array can be changed back to a single PCIe x8 interface through a new firmware load.

VMA-series Memory Array Installation and Service Guide

Page 30

Chapter 1 - VMA-series Overview

Once a Memory Array is connected to a host computer it can be partitioned into multiple volumes or virtual disks. Both Windows and Linux drivers are supplied for the specific operating system used on the host.

For data transfers, there are two PCIe x8 interface ports on the rear of the Memory Array. These interfaces support either single x8 or dual x4 PCIe connections. The port configuration is determined by the firmware image loaded on the system. See Upgrading the System Software on page 100 for more information on changing the firmware image.

For maximum performance to a single host or single memory ga teway, configure the system data interface as a single PCIe x8 connection using Port 1 (see

Figure 1.2).

For high-availability connections to two hosts or two memory gateways, configure the system data interface as dual PCIe x4 connections using Ports 1 and 2. This dual configuration allows each host to read and write to the same address space. When two hosts write to the same address, however, no guarantees are made for the order in which the operations are performed; hosts must manage potential conflicts via a clustered file system (e.g., GPFS) or some other technique.

Fibre Channel and iSCSI SAN Attach (vSHARE)

vSHARE provides scale-out block storage (SAN) capability. Memory arrays provide the flash memory storage and Memory Gateways provide the Fibre Channel and/or iSCSI connectivity and LUN management. Clusters of gateways and memory arrays can be built for extremely large-scale block storage systems.

Each Memory Array is managed as a container and multiple LUNs (volumes) are configured on the array. Each LUN can be independently sized and masked for use by different clients and clusters.

The same memory arrays and memory gateways can also be configured to use Ethernet (10GbE). Individual servers may be connected via multiple 1 Gb/s or 10Gb/s links to remove performance bottlenecks and extract the most value out of their processors and DRAM. vSHARE with iSCSI enables 10GbE connectivity between performance servers and performance flash memory arrays.

Violin Intelligent Memory Modules (VIMMs)

A VIMM, illustrated in Figure 2.1:

• Contains memory and interconnect diagnostics and error correction for data reliability.

• Offers data protection via a flash RAID (4+1Parity) function that provides fault tolerance and low latency access to flash.

A fully populated system contains up to sixteen Parity VIMMs and four spare VIMMs for failure protection. All memory modules are hot swappable with automated rerouting that will not interrupt data service. In the case of a module failure where the module must be replaced, the Memory Array does not have to be powered down.

VIMM Types

Figure 2.1 VIMMs

WARNING! Insert VIMMs or VIMM blanks only, otherwise permanent

system damage will result.

The Memory Array performance depends on the size of memory used and the number of modules. VIMMs are available in the capacities listed in the following table.

Page 35

Memory arrays store up to 64, 128, 256, or 512 GB of data per memory module providing up to 43 TB of raw flash storage per system. The amount of usable memory in a system is the number of VIMMs used for data storage, which is four per redundant array of independent disks (RAID) group (up to 64 VIMMs), multiplied by the amount of memory per module, multiplied by the usable percentage the system is formatted for. For example, in a fully loaded system with 84 VIMMs, the usable memory is 64 VIMMs multiplied by 128 GB, multiplied by the usable percentage, such as 87.5%, which is 7.2 TB.

VIMM Configurations

The Memory Array holds up to 84 VIMMs, which operate in the VIMM configurations listed in the following table.

Installing the Memory Array in a 19" Equipment Rack

The Memory Array fits into a standard 19" (482.6 mm) wide, four-post rack with sliding rails as specified by EIA-310-D, IEC 60297, and DIN 41494 SC48D. Square hole racks are supported.

Since there are a variety of 19" equipment racks available, the rack mounting brackets can be configured in several ways to accommodate a range of frontrear post spacings–from 24" to 32". This adapts the slide rails to the various equipment racks that may already exist at a customer’s site.

The Memory Array is extended via the slide rails to the front of the rack for live servicing. A cable management arm is used to manage and extend the cables for this process. To ensure there is sufficient room for the cable management arm to easily fit within the rack, it is required that rack depths of 36" or greater be used. Any doors on the rack must allow good front to back airflow.

Caution:

• Improperly spaced mounting brackets and slide rails can cause the

Memory Array to fall out of the rack.

• Because of the weight of the Memory Array, two people are required to

lift and place the system in an equipment rack.

• If installed in a closed or multi-unit rack assembly, the operating ambient

temperature of the rack environment may be greater than the ambient room temperature. Therefore, consider installing the equipment in an environment compatible with the maximum ambient operating temperature specified by the manufacturer.

• Install the equipment in the rack so that the amount of air flow required

for safe operation of the equipment is not compromised.

• Mount the equipment in the rack so that a hazardous condition is not

achieved due to uneven mechanical loading.

Note: You must be able to access the rear of the Memory Array and the

equipment rack during installation.

The following procedure describes how to:

• Install the sliding rails and mounting brackets onto the chassis if they have not been installed prior to shipping.

• Secure the chassis into the equipment rack. The rack mounting screws and nuts are included in the shipping package.

Rack-Mounting the Chassis

Figure 3.2 Installing the Memory Array into a Rack

To install the Memory Array into a 19" equipment rack:

1. Remove the Memory Array from the shipping packaging and remove all

packing materials. Visually inspect the system for any shipping damage and, if any damage is detected, contact HP Customer Support for replacement parts.

2. Install the toolless mounting rails at the appropriate height in your

equipment rack. Orient the rails so they slide out to the front of the rack.

3. Fully extend the rails until they lock into place. Position the Memory Array

above the rails and slide the buttons at the rear sides of the chassis into the rear slots on the rails.

4. Slip the remaining sets of buttons into the remaining cutouts in the rails.

Push the whole assembly back into the equipment rack and secure the rack mounting brackets to the front of the equipment rack with the thumb screws located on the front mounting brackets, as shown in Figure 3.2.

Installing the Cable Management Arm

Install the optional cable management arm at the rear of the chassis. The arm consists of a mounting bracket and cable holder and keeps the cables from becoming entangled when the system is fully extended from the equipment rack. The cables are routed along the length of the arm and held in place with cable ties. The cable management arm is not installed prior to shipping.

To install the cable management arm:

1. At the rear of the chassis, remove the shoulder screws and shims from the

rear equipment frame mounting bracket and set aside. Orient the cable management arm mounting bracket on the right, as illustrated in the figure below.

Figure 3.3 Installing the Cable Management Arm Mounting Bracket

Align the thumb screws on the cable management arm mounting bracket

with the installation holes on the right rear of the chassis. Securely tighten the thumb screws into the chassis.

3. Using the four (4) shoulder screws and shims that were set aside in step 1,

secure the cable management arm mounting bracket to the rear equipment frame mounting bracket, placing the shim between the shoulder screws and the cable management arm mounting bracket, with the enclosed Hex key. The cable management arm mounting bracket slides the arm forward and enables the chassis to be fully extended from the equipment rack for accessibility.

4. At the rear side of the system, using the two (2) SEM 10-32 x 0.50 screws

included in the shipping package, secure the cable holder to the equipment rack over the rear equipment frame mounting bracket on the right side of the system as illustrated in the figure below.

2. Route the equipment ground cable to the rear of the equipment. Be sure to

leave an appropriate service loop to allow the removal of the equipment on the slide rails. If using the cable management arm, route the equipment ground wire around the arm. See Routing the Cables onto the Cable

Management Arm on page 55.

3. Cut the length of the ground wire at the rear of the equipment as needed

for proper fit. If the length of the cable is cut, strip 13 mm (½ in) of insulation from the cut end of the cable for installation into the grounding lug.

4. Attach the ground cable to the loose grounding lug provided with the

Memory Array. Tighten the screw on the lug to secure the cable to the lug.

5. Using the grounding screw provided with the Memory Array, attach the lug

to the ground point on the rear of the equipment.

Note: Attach the lug with the cable pointing up. Attaching the lug with the

cable pointing down may cause interference between the ground cable and equipment mounted directly below the Memory Array which would prevent the Memory Array from sliding out of the equipment rack for serviceability.

If ground cable not included in accessory kit

When installing a grounding cable, be sure to allow a sufficient service loop to allow the array to be removed from the front of the rack for serviceability.

One end of the grounding cable should be attached to an appropriate ground location on the equipment rack. The other end of the ground cable should be attached to the grounding location on the rear of the Memory Array using a ¼-20 x ½" (max length) size screw.

Connecting the PCIe Cable to a Host Computer or Memory

Gateway

The Memory Array is connected via external PCIe cables (PCIe x8 cables) to one or two host computer(s) or memory gateway(s). Hosts support applications, such as databases, and run operating systems such as Linux or Windows. Memory gateways provide network connectivity to SANs or LANs.

The Memory Array can be connected as a direct-attached storage system which is either dedicated to a single host or shared between two hosts. Where the Memory Array is shared across two hosts, the PCIe connections are logically PCIe x4, but use PCIe x8 cables and interfaces.

A single host may connect to multiple memory arrays, enabling capacity and performance to scale as needed. The host requires a PCIe Host Interface Board (HIB) for each memory array that is to be connected.

Host Computer

The steps for connecting the Memory Array to a host computer are:

1. Install the necessary PCIe HIB card into an available PCIe slot in the host

computer, ensuring that it is securely seated.

2. Orient the unconnected end of the PCIe cable(s) to align with the PCIe

connector on the back of the host computer. The PCIe cable is keyed and only goes in one way.

3. Securely plug the cable(s) into the PCIe connector, as illustrated in the

figure below.

Routing the Cables onto the Cable Management Arm

After installing the Memory Array in an equipment rack and attaching the necessary cables at the rear of the system, route the cables along the cable management arm to prevent them from becoming entangled when the system is fully extended from the equipment rack. Route the cables along the length of the arm and hold in place with cable ties.

To route the cables along the cable management arm:

1. Extend the cable management arm by removing the screws from the

equipment rack, holding the chassis brackets, and pulling out the Memory Array from the equipment rack. Do not remove the system from the rack.

2. At the rear of the chassis, route the installed ground wire, serial cable, and

power cables along the length of the cable management arm and secure them with cable ties. Slip the cable ties around the slits in the arm and secure the ties around the routed cables.

3. Route the PCIe cable along the cable management arm and above the

hinge in the middle of the arm. Routing the PCIe cable above the hinge ensures that when the system is in place in the equipment rack, the cable radius stays above the minimum radius for PCIe cables.

Note: The minimum radius bend for a PCIe cable is 1.9".

4. Push the Memory Array back into the equipment rack and secure it to the

equipment frame using the screws that were removed earlier.

Changing the Default IP Address, Netmask, and Gateway

The Memory Array supports assigning IP addresses either statically or through DHCP. The IP address, netmask, and gateway are initially set to default values, see Table 4.1. Change these values to valid addresses within your network to access the system CLI.

By default, DHCP is disabled. For convenience, the Ethernet port supports automatic medium-dependent interface crossover (Auto-MDIX). With this, you can connect the Ethernet port on the system to a computer's Ethernet port, such as a laptop, for provisioning before connecting to a network switch.

You can switch between using DHCP and static addressing. When switching from DHCP to static addressing, the Memory Array uses the default address values if new values have not been pre-provisioned in the CLI. Alternatively, an IP address can be assigned while DHCP is enabled and that IP address is used automatically when switching from DHCP to static IP address assignment (i.e., DHCP is disabled).

HP-AM456-9002A Rev 01

Note: It is recommended to manually configure the IP address of the Memory

Array to use a static IP address in the DHCP configuration file. If the IP address is automatically assigned there is a risk of the system being assigned a different IP address upon reboot.

Configuring Domain Name System (DNS)

There are two available methods for configuring DNS on the Memory Array:

1. Automatic DNS configuration

2. Manual DNS configuration

The Memory Array also allows pre-provisioning the DNS information to use when you change your system from automatic DNS configuration to manual. If the DNS configuration is currently in automatic mode, then the current automatically provisioned DNS name and search information is considered to be the provisioned settings used when the mode is set to manual.

By default, DNS configuration is performed automatically when Dynamic Host Configuration Protocol (DHCP) is enabled and connected to a DHCP server that supports specifying the DNS name. If DHCP is disabled, then the DNS mode is automatically changed to manual.

Note: Pre-provision the DNS configuration information before disabling DHCP.

Disabling DHCP forces the DNS mode to change to manual and use the default values, making the system unreachable.

Configuring the DNS Name

When in automatic DNS mode and you set the IP address of the DNS name server, you are pre-provisioning the value. It is not used until you change the DNS mode to manual. You can configure the DNS name server’s IP address at any time.

To specify the IP address of the DNS name server of the Memory Array:

1. Log into the CLI via a serial connection or the Ethernet interface (see

Connecting to the CLI on page 59).

2. Navigate to the

context chassis controller ethernet 0

3. At the

Verifying the Ethernet Connection

The Ethernet interface can also be used to connect to the CLI of the Memory Array. This section explains how to verify that the Ethernet connection is operating properly.

To verify the Ethernet connection:

1. Log in to the host computer, as root on a Linux host or as an

administrator on a Windows host.

2. To retrieve the IP address of the Memory Array, do one of the following:

a. Log into the CLI via the serial port connection (see Logging into the CLI

via the Serial Interface on page 59) and type the following command at

the command prompt:

show chassis controller ethernet 0

This command returns the system’s IP address and other Ethernet settings.

b. Connect to your DHCP server and retrieve the IP address it assigned to

your Memory Array.

3. Open a terminal or command line window and, at the command prompt,

type:

$ ping {<memory-array_ip_address> | <memory-array_name>}

Where:

memory-array_ip_address The IP address assigned to the

Memory Array.

memory-array_name The name of the Memory Array if

using DHCP and the memory array is registered in the DNS.

If the host computer can connect to the Memory Array, then it will return a successful ping message. If it cannot connect, then a failed ping message is returned.

You can also connect to the system via the Ethernet port using Telnet or SSH as described in Connecting to the CLI on page 76. If you are using DHCP and DNS, you can use the system’s name instead of the IP address to connect through the network.

Displaying and Setting System Log (Syslog) Options

The Memory Array logs system messages that can be sent to a host running a syslog server for long term storage. If numerous messages are generated, then the log buffer may fill up and, since it is a circular buffer, overwrite older messages. The message level mapping between the message level definitions and your host’s syslog message level definitions are listed in Table 4.3. View the man page for syslog.conf on the host for more information.

Table 4.3 Syslog Definition Mappings

Memory Array Syslog

DEBUG debug

INFO info

WARNING warn

ERROR emerg

FATAL emerg

When syslog messages are received on the host, they are written to whatever logging device is configured. Frequently, this means that warn messages are written to a file, such as /var/log/messages or /var/adm/messages, and emerg level messages are written to all root consoles. On the Memory Array, messages that are set to the WARNING, ERROR, or FATAL level are sent to the host.

Displaying the Configured IP Address of the Syslog Host

Rebooting the Memory Array

When you reboot the Memory Array, you must specify which processors to restart. The two processors are:

1. System—Contains the software that manages the VIMM topology.

WARNING! Restarting the system processor interrupts traffic and

causes loss of some older system logs and diagnostic data. To preserve this diagnostic data it is recommended that the vincident and/or save

log commands be used prior to reboot.

Using a syslog server also ensures logs are stored prior to any reboot. See

Displaying and Setting System Log (Syslog) Options on page 71.

2. OAM—Controls the administration function, such as user logins, system

administration, and the CLI software.

Rebooting the System

Set the system reboot to run immediately or to be delayed in minutes, up to 1 day.

1. Log into the Memory Array.

2. At the root prompt, type:

reboot system {all | oam} [delay <n>]

Where:

all Reboots both the

System

and

OAM

processors.

oam Reboots only the OAM processor delay <n> Sets the time delay in minutes for rebooting the

system. Valid values are in the range of 1 to 1440.

If you do not specify the time delay, you are also prompted whether you want to reboot the system immediately. Answer y to reboot immediately. If you answer n, the immediate reboot request is cancelled.

You are prompted to confirm scheduling the reboot. If you confirm the reboot it will be scheduled. While the system is rebooting, you will lose your CLI connection and have to log back into the interface.

Canceling a Scheduled Reboot

1. Log into the Memory Array.

Upgrading the System Software

To upgrade the software on the Memory Array, perform the following steps:

1. Copy the upgrade image to a location on a host that is accessible to the

Memory Array target system using FTP, HTTP, NFS, SCP, SFTP, or TFTP.

2. Set the upgrade path to the above location. The upgrade image will

download to the upgrade partition of the Memory Array.

3. Set the upgrade partition to activate upon bootup.

4. Schedule the system reboot.

5. Reboot the host server.

6. Update the system software factory image.

Note:

• If you are upgrading from a previous release to the most current release, see the user documentation associated with the previous release for detailed upgrade instructions.

• If you are upgrading from a release prior to R2.2.0, before rebooting, you must use the following command to make the upgrade partition active upon reboot:

set system sw-upgrade active upgrade

The file name of the upgrade image is different depending on the PCIe interface you are using to connect to the Memory Array. The table below lists the image names.
