Considerations for scalability

You can scale your McAfee ePO infrastructure in multiple ways. Scaling is needed if the environment managed by McAfee ePO is growing beyond the capacity of the current McAfee ePO infrastructure.

To grow your McAfee ePO infrastructure, you can: Move the McAfee ePO SQL database to a larger and more powerful SQL Server, add more Agent Handlers, or increase CPU and memory to improve storage performance on the SQL Server.

With McAfee ePO software, you can scale your network vertically or horizontally.

  • Vertical scalability — Adding and upgrading to bigger, faster hardware to manage larger and larger environments. Scaling vertically is accomplished by upgrading your server hardware, and installing McAfee ePO on multiple servers throughout your network, each with its own database.
  • Horizontal scalability — Increasing the size of the environment that one McAfee ePO server can manage. Scaling horizontally is accomplished by installing additional Agent Handlers, all sharing a single database.

    Make sure the McAfee ePO infrastructure is scaled to handle major peaks in outbreak situations.

Managed systems and servers

The number of systems your McAfee ePO server manages dictates the number and size of the servers needed. It also dictates the recommended server sizing needed to manage these systems.

Option < 1,500 systems 1,500–10,000 systems 10,000–25,000 systems 25,000–75,000 systems > 75,000 systems
Virtual McAfee ePO server Yes Yes Yes Yes Yes
Virtual SQL database server Yes Yes Yes Conditional* Conditional*
McAfee ePO server and SQL database on the same server Conditional* Conditional* Conditional* Conditional* Not recommended
Add distributed repositories Not required Conditional* Conditional* Yes Yes
Add Agent Handlers (virtual) Not required Conditional* Conditional* Yes Yes

*For more information, see Combining servers.

Tip: We recommend one Agent Handler for every 50,000 systems.

There is no hard limit on the number of systems McAfee ePO can manage. The primary limitation is the SQL database performance, specifically disk performance (IOPS – I/Os per second). You can scale the SQL database, add distributed repositories, and add Agent Handlers to manage more systems as needed.

Important sizing considerations

  • Environment — Estimates based on a McAfee ePO server running the Endpoint Security products.
  • Operating systems — You must use a 64-bit operating system for the McAfee ePO server and SQL Server.
  • CPU cores — Server class, minimum 2.2 GHz.
  • RAM — Add 16 GB of RAM to SQL Server for every 25,000 nodes.
  • Storage capacity — Estimated event retention period of 6 months.
  • Storage performance — Storage estimated event retention period of 6 months.

Recommended hardware based on number of managed systems

Node count McAfee ePO server
CPU cores RAM (GB) Storage (GB)
< 10,000 4 8 300
10,000–25,000 4 8–16 500
25,000–75,000 8 16–32 500
75,000–150,000 12 16–64 500
150,000 + 16 16–64 500

Node count Agent Handler

< 10,000 You can use a single server or multiple VMs.
10,000–25,000 0–1 4 8 150
25,000–75,000 0–1 4 8 150
75,000–150,000 1–3 4 8 150
150,000 + 3+ 4 8 150

Node count SQL Server
CPU cores RAM (GB) Storage (TB) Performance (IOPS)
< 10,000 4 8–16 0.5–1.0
10,000–25,000 4 8–16 0.5–1.5
25,000–75,000 8 16–32 1.0–2.0 >10,000
75,000–150,000 16 32–128 2.0–3.0 >30,000
150,000 + 32+ 128–256 3.0 >90,000

By default, IOPS is calculated with 4-KB sectors. Microsoft recommends that SQL storage solutions are allocated with a 64-KB sector size.
