Networking and Split-Site Considerations

Before Installing your Avance servers it is important to understand the networking requirements, additional attention should be made if your are planning to run a split-site configuration.

General Network Requirements

Both of the physical network ports (one on each node) that make up a shared network on an Avance system must be in the same L2 broadcast domain, without any protocol filtering.  Any and all Ethernet packets sent by one Avance node must not be obstructed or rate limited from being received by the other Avance node either by being routed or switched by any L3 network infrastructure.

Avance relies on full IPv4 and IPv6 protocol access, including IPv4 and IPv6 multicast.  Any obstruction of this traffic will prevent a successful install or will compromise the availability of the Avance deployment.  Avance should never generate more than 10 multicasts per node per second on any one network link.

Private Network Requirements

The first onboard Ethernet port on each node must be connected via a private network.  These ports are usually labeled “GbE1”, “NIC1”, etc on the physical server, and the private network that connects the two Avance nodes is called “priv0”.  The private network must have no other network hosts connected.  The simplest private network consists of a single Ethernet cable (crossover or straight through) that connects the first onboard Ethernet port on each server.  If a single Ethernet cable is not used for the private network, see Split-Site Considerations below for additional requirements.

10Gb Sync Network Requirements

Avance may also use 10Gb Ethernet ports as private sync networks.  Network traffic for storage replication between nodes is sent over these networks if they are present.  The requirements are similar to the Private network, as these networks should have no other network hosts connected other than the Avance end points.  If a single Ethernet cable is not used for any of the sync networks, see Split-Site considerations below for additional requirements.

Business Network Requirements

All Ethernet ports, other than 10G Ethernet ports and the Private Network port (first onboard Ethernet port), are treated as Business Networks, which VMs can use to pass traffic.  In order to ensure that Ethernet traffic flows unobstructed to and from VMs from either Avance node:

  • The switch ports connected to Business Networks must not filter ARP packets including gratuitous ARP packets.  Avance will send gratuitous ARP packets on behalf of guest VMs in order to prompt Ethernet switches to update their port forwarding tables to direct VM traffic to the appropriate physical Ethernet port on the appropriate Avance node.
  • The switches connected to Business Networks must not enable any MAC address security features that would disable the movement of a MAC address from one business link to the matching business link on the other node.  Cisco Catalyst switches, for example, support MAC address security features which must be disabled.

If these requirements are not met, or if the switch does not properly update it’s forwarding table when a VM is migrated from one Avance node to the other, the VM may experience a blackout where network traffic is not properly directed to and from the VM.

Split-Site Considerations

If the Private Network or any 10G Sync Networks pass through any networking equipment (i.e. are not connected by just an Ethernet cable), then the requirements outlined in this section must also be met.

Private Network Requirements

  • Switch ports and/or fiber-to-copper converters connected to the Private Network must be set to auto negotiate Ethernet rates and must also support negotiating to both 100Mb/s and 1000Mb/s speeds.  This is a common configuration error made with split-site deployments.
  • Switches and/or fiber-to-copper converters connected to the Private Network must be non-routed and non-blocking with a round-trip latency that does not exceed 10ms.  Calculate latency at 1ms for each 100 miles of fiber, and around 1ms for each non-routed, non-blocking switch or fiber converter.
  • VLANs used to connect the Private network ports must not add any filtering on any of the network equipment between the two VLAN switch ports that are connected to the Avance unit nodes.

No Single Point of Failure

The path taken between Avance nodes in the Private Network must be physically segregated from the path taken by traffic on the Business Networks.  Avance determines liveness of each node by sending heartbeat communication on the Private Network and the first Business Network (example “GbE2”, “NIC2”, etc of each physical server).  If a single physical device or software service fails which causes traffic on both the Private and first Business Network to fail, the Avance nodes may split-brain.  If Avance nodes split-brain, they will each start and run the guest VMs, which will corrupt the VM data (e.g. which copy is correct?) and will have two instances of the same VM communicating on the Business Networks.

Site and System Preparation | HP

Site and System Preparation

Site Prep 1: Prepare Required Equipment and Information

Connection required during system preparation and Avance installation Two physical machines (PMs)

  • Server model/configuration conforming to Avance Compatibility Matrix, for HP Servers.
  • PMs are similar configurations from identical product family/generation
  • At least two disks each (except HP ML370 G5, which requires at least 4)
  • Either an internal DVD drive or USB DVD drive can be used for the installation.

Use keyword “firmware” and release “3.0″ to search the Known Issues database to check for any firmware incompatibilities prior to upgrade or install.

  1. Login to the Avance Customer or Partner Portal.
  2. Click on Search for known issues under technical support.
  3. Select release 3.0 and issue type firmware.

CAT5E, CAT6, or CAT7 network cables for all network ports Monitor and keyboard for system preparation and installation Computer for Avance Management Console

Site Prep 2: Configure Networks

Private Network Connect a network cable between the first embedded network port of each PM, which should be labelled port1.

See Planning for Split Site Deployment if the PMs are in separate locations. Storage Sync Networks (Optional) Avance supports additional Sync links for increasing data replication performance between PMs. These links must be dedicated 10Gb and connected between PMs in the same manner as the private link. Setting up redundant Sync links is recommended. Business Networks Connect Ethernet cables from the second embedded port in each PM to the business network, which should be labelled port2.

If the network includes a large number of add-on business network (NIC) ports,  defer installation until the basic install is completed. Refer to the section entitled Connecting Business Links  for  more details.

Site Prep 3: Configure Storage

Each physical machine must have at least two physical disks populated in the server’s lowest numbered slots. Exception: HP370-G5 systems require an additional 2 disks placed in slots 8 and 9.

  • Configure the RAID controller to boot off the first logical disk.
  • Each RAID array can have only one logical volume assigned to it.
  • RAID 0, 1, 5, 6, and 10 are the only RAID levels supported.
  • Set up RAID configurations identically on both physical machines before installing Avance software.
  • If the 1st logical disk is RAID 1, 5, 6, or 10, Avance will apply an MBR format.
  • If the 1st Logical disk is RAID 0, Avance requires a 2nd logical disk of any RAID type. Avance will apply an MBR format.
  • Multiple HP RAID controllers of the same type in the same node are not supported.

Site Prep 4: Connect Power

Configure servers with redundant power supplies connected to separate sources. UPS (Optional) Connect one or two uninterrupted power sources (UPS) to the Avance unit: Single UPS Dual UPS Remote Power Control For remote locations, consider a networked UPS or switched Power Distribution Unit (PDU) such as provided by APC. These enable remote power-cycling of PMs through a network.

Site Prep 5: Configure BIOS

Avance automatically configures most required BIOS settings. There are some optional settings which the user may want to consider:

AC Power Recovery Several server vendors allow you to configure whether or not the server will automatically power on and boot after a power cycle. We recommend setting this to ON.
NIC PXE Boot Support Several server vendors allow you to configure whether or not network ports will be used to PXE boot a PM. Avance requires that the first onboard NIC port be enabled for PXE, but not any others. We recommend disabling PXE boot on all NIC ports *except* the first onboard NIC port.

HP DL180 G6 Server BIOS Initialization

  1. Connect a monitor and keyboard to the first physical machine (PM).
  2. Power on the PM.
  3. Hit F10 when prompted to enter the ROM-based Setup Utility.
  4. Set IPMI Configuration -> Set LAN Configuration -> BMC NIC Allocation to Shared
  5. The following settings should be correct if left at the default.
    1. CPU Configuration -> Intel Virtualization Tech Enabled
    2. Set CPU Configuration -> Execute-Disable Bit Capability Enabled
    3. Set CPU Configuration -> Embedded NIC Port 1 PXE Enabled
    4. Set PCI Configuration -> Execute-Disable Bit Capability Enabled
  6. Leave boot order at the default order
    1. Network
    2. CD/DVD
    3. Hard Drive

Creating HP Tools

The installation of Avance on an HP servers, requires an additional step to install some HP tools utlized by the Avance software to manage your servers.

Creating HP Tools Media

  1. Create a folder titled avancetools on your PC.
  2. Go to www.hp.com. Search for the following HP tools (filenames in bold). Download to the avancetools folder. Current file links are also listed.
    1. HP Array Configuration Utility CLI for Linux – HP Business Support Center hpacucli-9.0-24.0.noarch.rpm
    2. HP Lights-Out Online Configuration Utility for Linux – HP Business Support Center hponcfg-4.0.0-0.noarch.rpm
    3. HP SNMP Agents for Red Hat Enterprise Linux 5 (x86) – HP Business Support Center hp-snmp-agents-
    4. Insight Management MIB update kit for HP Systems Insight Manager for Linux/HP-UX – HP Business Support Center, version 8.40 (29 Mar 2010) upd900mib.tar.gz
    5. HP System Health Application and Command Line Utilities for Red Hat Enterprise Linux 5 (x86) – HP Business Support Center hp-health-
    6. SmartStart Scripting Toolkit Linux Edition – HP Business Support Center hp-scripting-toolkit-linux-9.00.tar.gz

Make sure the files you download and install have the filenames listed above. For best results, download the files to the computer you will use to create the tools media.

  • Copy the files from the avancetools folder to a CD/DVD-ROM or USB memory stick. For instructions, see your computer’s online help.
    1. Burn utilities and CD/DVD-ROM hardware must support and use the Disk-At-Once (DAO) method. Stratus recommends burn utilities that default to DAO mode, such as http://www.imgburn.com/.
    2. Use only new CDs/DVD-ROM discs.
    3. Write only to the root directory of the USB stick or CD/DVD-ROM. Do not write to a folder.
    4. The Avance installation program will not recognize some older USB sticks.
  • CD/DVD-ROM only: Verify the new disc.
