Server system

A device comprising

• a server node configured to mount in a server system chassis, comprising:
• multiple sub-node chassis;
• and
• an array of devices, wherein segments of the array of devices of the server node are mounted in respective ones of the multiple sub-node chassis of the server node, wherein the array of devices comprises mass storage devices,
• wherein each sub-node chassis is configured to be individually installed in the server system chassis;
• and
• wherein each sub-node chassis comprises an intra node connector configured to couple with an intra node connector of an adjacent sub-node chassis to allow communications to or from devices mounted in separate ones of the multiple sub-node chassis of the server node.

A method comprising:

• installing a sub-node chassis in a server system chassis mounted in a rack, wherein the sub-node chassis comprises a portion of an array of mass storage devices of a server node;
• installing an additional sub-node chassis in the server system chassis, wherein the additional sub-node chassis comprises an additional portion of the array of mass storage devices of the server node;
• and
• causing an intra node connector of the sub-node chassis to couple with a corresponding intra node connector of the additional sub-node chassis to allow communications to and from the mass storage devices in the sub-node chassis.
