Configuring Veeam with HPE StoreOnce

So you are implementing Veeam and need a dedupe appliance for repository but not sure which one to select. I was in the same position an year back. There was an inclination from higher up for HPE StoreOnce. But there wasn’t enough data out there (or maybe I couldn’t find it) on the expected dedupe ratios with Veeam backup.

Finally after multiple back and forth with HPE and a written guarantee on a minimum expected dedupe ratio, we bought HPE StoreOnce 5100. Here is my experience.


  • 2 x 16Gb FC HBA’s
  • 4 x 10Gb Ethernet (2 x dual port card)
  • Capacity: 106TB

FC connection between StoreOnce and a bare metal Windows server with Veeam gateway role.

StoreOnce Setup

Assuming the initial configuration has been completed for StoreOnce, perform the following steps to create a StoreOnce catalyst as a Veeam repository.

HPE StoreOnce Catalyst deduplication is not global to the appliance but rather local to individual catalyst stores. This can have a significant impact how you design catalyst stores for use as repositories. 

  • Create a StoreOnce Catalyst client. The name needs to be named “Veeam“. Create a password. You will use this within Veeam to add the repository

  • Next go to Stores within Catalyst to create a store. You will add this as a repository within Veeam.

  • Next add the client you created in the first step to the store, enabling “Access

  • Next step would be to add this Catalyst store to Veeam, assuming all fabric zoning has already been configured to the gateway server.


Veeam Configuration

  • Add the gateway server to Veeam as a backup proxy.
  • Add new backup repository in Veeam.

  • Select Deduplicating storage appliance
  • Select HPE StoreOnce

  • Select checkbox Use Fibre Channel connectivity. This adds in COFC- to the server name. This is required if connecting through FC. Add in the FQDN of the StoreOnce after COFC- e.g.

  • In credentials, add the Veeam client that was created in StoreOnce earlier
  • In the Gateway Server, select the gateway server
  • If everything is configured correctly, select you will select the Catalyst store

  • For the concurrent tasks, this will depend on the number of connections between the gateway server and StoreOnce

  • Review the settings and finish the wizard. Congratulations you have just added in a StoreOnce Catalyst store to your Veeam



This is what we are seeing one year after implementation

General repository (predominantly Windows server backups) – 16:1

Microsoft Exchange backups – 23:1

File Services backup – 23:1

Hope this is helpful to someone.

Partitioning a HPE MSL4048 Tape Library

The HPE MSL4048 tape libraries can be partitioned into logical libraries to match the number of tape drives installed.

You can have 2 full height tape drives in MSL4048 or 4 half-height tape drives.

In this example, we are partitioning the physical library into two logical tape libraries using two half-height tape drives. The physical library is connected to the hosts (servers) through FC switches.

  • Ensure the tape drives are connected to slots 1 & 3 in the library. If moving the tape drives to different slots, ensure you change the FC zoning as the WWPN is for the slot and not the tape drive (makes sense – ability to replace drives without requiring any additional change)


  • Login to HPE Command View (IP address of the tape library) using a web browser. Remember to login as an AdministratorScreen Shot 2017-05-13 at 11.58.10


  • Go to Configuration –> System


  • Change Select Mode to “Two Logical Libraries” and select “Apply” This option will only be available if the tape drives are in correct slots.

  • Ensure all other settings are correct to match your environment. Once complete, drive 1 will be allocated the left enclosure and drive 2 takes up right enclosure.


  • If mail slot is enabled, logical library 1 (tape drive 1) will lose 3 slots to mail slot reducing its slot count to 21 while logical library 2 (tape drive 2) will have 24 slots.

  • Now configure FC zoning to map servers to their own logical tape libraries.
