Add storage capacity to the ETA 6150 or 8250
Adding additional storage capacity to your ExtraHop packetstore enables you to store more packets and extend the amount of lookback available when running packet queries. You can safely add ExtraHop Extended Storage Units to a packetstore and retain all packets currently stored on the packetstore.

Set up the extended storage unit

- Connect the power cables to the power supply units (PSUs).
Shut down the packetstore

Connect the extended storage unit
The extended storage unit connects to the packetstore through both of the two enclosure management modules (EMMs). Each EMM has four ports for connecting the SAS cables.
In a redundant configuration, the storage units are linked together in a series, with one of the extended storage units connected to both host bus adapter (HBA) ports on the packetstore, as shown in the following figure.
