How To: Upgrade the memory on your B Model appliance

Introduction

With increased memory requirements in 7.5.x and beyond, Intel Security has recently started selling memory for the B model appliances. This will make the process easier to get your appliance up to minimum specs. Below, I'll highlight how you can identify your appliance model and determine how much memory you need. Once you've taken proper inventory you will be equipped to provide the information to your Salesperson and purchase the new memory. Here is Intel Security's tamper seal statement: McAfee KnowledgeBase - Email Gateway and Web Gateway Tamper Seal Statement . Before installing the memory it is advisable to open a support case simply to document that you are planning to upgrade the memory, no further action is required.

 

IMPORTANT: You can stop reading if you have a C model appliance (on sale since Nov 2013).

 

Determine appliance model

Run the "mwg-info model" command from the CLI of the appliance. You should get output similar to whats found below:

 

# 4000B

AP;MWG4000;McAfee, Inc.;Appliance A1H;2*Intel(R) Celeron(R) CPU E3400 @ 2.60GHz;3921164kB;2*e1000e, 1*e1000

# 4500B

AP;MWG4500;McAfee, Inc.;Appliance A3;4*Intel(R) Core(TM) i3 CPU 540 @ 3.07GHz;3821516kB;4*igb, 1*e1000e

# 5000B

# 5500B

AP;MWG5500;McAfee, Inc.;Appliance A5;24*Intel(R) Xeon(R) CPU X5660 @ 2.80GHz;12135332kB;2*igb, 2*e1000e

IMPORTANT: Second warning, you can stop reading if you have a C model appliance (on sale since Nov 2013).

Check existing memory

It is a good idea to verify that the memory has not already been upgraded. Run the command "free -g" to determine how much memory is currently installed.

 

Hardware Service Guides

For further reference, please checkout the service guides for your specific appliance. These guides will go into further detail regarding the steps to install the memory.

4000B

The 4000B comes with 4GB of memory (2GB*2 or 1GB*4), the system configuration supports a maximum of 8GB of memory. Intel Security now sells an upgrade kit which will give you 8GB of memory in the system (SKU: WBG-4000-MEM: 4x DIMM,2GB, 667MHZ, DDR2,ECC).

 

4500B

The 4500B comes with 4GB of memory (2GB*2 or 1GB*4), the system configuration supports a maximum of 8GB of memory. Intel Security now sells an upgrade kit which will give you 8GB of memory in the system (SKU: WBG-4500-MEM: 4x DIMM,2GB, 1333MHZ, DDR3,ECC). The 4500B only supports UDIMM memory modules and has a Intel Core i3 processor installed. Use two sticks per memory channel. Here is an example memory configuration:

    • 2GB in DIMM A1
    • 2GB in DIMM A2
    • 2GB in DIMM B1
    • 2GB in DIMM B2

 

  

5000B

The 5000B comes with 6GB of memory (2GB*3 or 1GB*6), the system configuration supports a maximum of 48GB of memory. Only one of the CPU sockets is used, as such only certain memory banks can be used. See diagram below which show what CPU slot corresponds to what memory banks. Intel Security now sells an upgrade kit which will give you 24GB of memory in the system (SKU: WBG-5X00-MEM: 6x DIMM, 4GB, 1600MHZ, DDR3, REG, ECC). Fill all of the slots on the corresponding CPU banks.

 

5500B

The 5500B comes with 12GB of memory (2GB*6 or 4GB*2+2GB*2), the system configuration supports a maximum of 96GB of memory. Intel Security now sells an upgrade kit which will give you 24GB of memory in the system (SKU: WBG-5X00-MEM: 6x DIMM, 4GB, 1600MHZ, DDR3, REG, ECC). Here is an example memory configuration:

    • 4GB in DIMM A1
    • 4GB in DIMM B1
    • 4GB in DIMM C1
    • 4GB in DIMM D1
    • 4GB in DIMM E1
    • 4GB in DIMM F1

 

Purchasing the memory

Reach out to your sales person and give them the SKU which corresponds to your appliance model (WBG-4000-MEM, WBG-4500-MEM, or WBG-5X00-MEM).

Frequently Asked Questions

  • Can I install more than 8GB of memory into my 4000B or 4500B? No. This is due to the type of memory required by the motherboard when a certain CPU is installed. This combination means that UDIMMs are required, and for the 4500B, this also means we cannot use all of the memory banks.
  • Can I keep/reuse the existing memory in my 4500B? No. This appliance configuration only permits 4 out of the 6 memory slots be used when UDIMMs are required (they are required for this system configuration).
  • Can I install more than 24GB of memory into my 5000B or 5500B? No. Yes and other customers have done this. There was not much performance gains from extra memory. As such, McAfee is only selling the vetted recommendation of 24GB for both 5000B and 5500B. Using untested memory modules might lead to strange issues like sporadic reboots, system stalls, kernel panics, slowness, and uncorrectable memory errors.
  • Can I keep/reuse the existing memory in my 5500B appliance when I add extra memory (12+24=36)? Yes, but the memory speed may vary (new modules are 1600 MHZ). No, it is recommended to only use the new memory and discontinue using the old memory sticks.

 

B Model EOL

The EOL for B model appliances is in 2019. 4000B/4500B appliances are EOL in Dec 2019, and the 5000B/5500B appliances are EOL in Mar 2019. More information can be found on the EOL page: Intel Security Product & Technology Support Lifecycle – End of Life (EOL) – End of Support | Intel S...

Hi, I'm running two nodes (virtual appliances) in a HA Cluster with central management on Version 7.4.2.3.0 and would like to upgrade to 7.6.2.6,

this is the mwg-info model Output:

VM;VMWare;VMware, Inc.;VMware Virtual Platform;4*Intel(R) Xeon(R) CPU X5690 @ 3.47GHz;8057384kB;2*e1000

so none of the above mentioned models really fit.. could you please tell me which model recommendation I should use? both nodes have already 8GB RAM each.. (and if this is relevant: each node has around 100requests per second)

Please help!

Thanks very much in advance!!

Hi Renata,

This guide is written to help customers using appliances upgrade their memory (which requires specific memory modules). You're running MWG's in VMWare, so you can just increase the memory in the hypervisor (VMware) unless the physical host needs memory. If the physical host needs memory then you'll need to look up the requirements for that server.

If you're asking how much memory you should have, the installation guide goes into more details about minimum and recommended specs depending on your deployment.
