Block chassis sled having one-third width computing and storage nodes for increased processing and storage configuration flexibility within a modular, scalable and/or expandable rack-based information handling system
Modular, expandable rack assembly physically supports components of information handling systems. Base structure of interconnected panels form volumetric space having front section and rear section, with opposing side panels forming front access space and rear access space, respectively, having width that supports insertion of standard full-width IT gear. Guides are located within interior surfaces of opposing side panels at the front section to rear section. Block chassis has frame that provides block height to enable insertion of at least one layer of up to N side-by-side fully functional IT gears within block chassis, which in turn is physically inserted into front section of base structure and held in place by opposing guides of opposing side panels. When N is 3, three side-by-side one-third width IT sleds, each containing IT gear, are inserted in respective one-third width IT bays of block chassis.
1. A rack-based information handling system (IHS), comprising: a modular, expandable rack assembly having opposing sidewalls spaced to receive block chasses capable of housing a plurality of information technology (IT) components from an open front side of the rack assembly, the block chasses insertable into the rack assembly and having one or more rows for insertion of IT sleds; three side-by-side one-third width IT sleds, each sled configured with opposing having side panels connected by a base panel and containing IT gear, the three side-by-side one-third width IT sleds inserted in one of the one or more rows ; and a vertical busbar attached to a rear side of the rack assembly, wherein each of the block chasses comprises a horizontal busbar providing an electrical connection at a rear of each one-third width IT bay and aligned to electrically connect to the vertical busbar to provide electrical power to each of the one-third width IT sleds in response to the block chassis being inserted into the rack assembly.
2. The rack-based IHS of claim 1 , wherein the block chassis comprises guides defining one-third IT bays for insertion of one-third width IT sleds within the one or more rows of IT sleds.
3. The rack-based IHS of claim 1 , wherein the one-third width IT sleds have flat side panels aligned for flush alignment with an adjacent one-third width IT sled for frictional slideable insertion and removal.
4. The rack-based IHS of claim 1 , wherein a right side panel of a selected one-third width IT sled has horizontally aligned contour of an indentation and a protrusion that is mirrored by a corresponding left side panel of a left adjacent one-third width IT sled for guided, slideable insertion and removal of one of the selected and adjacent one-third width IT sleds.
5. The rack-based IHS of claim 1 , wherein the one-third width IT sleds each have a width that is less than or equal to one-third of a standard nineteen (19) inch width rack that, in lateral flushed alignment and slideable with an adjacent one-third width IT sled, combine to represent a 19-inch wide interior space of the block chassis.
6. The rack-based IHS of claim 1 , wherein the three side-by-side one-third width IT sleds contain one or more of computing IT gear, non hot plug storage IT gear, a hot plug storage IT gear, and Just A Bunch Of Disks (JBOD) storage IT gear.
7. The rack-based IHS of claim 1 , wherein the one or more one-third width IT sleds contain IT gear oriented depthways along a motherboard from front to back.
8. The rack-based IHS of claim 1 , wherein a selected row of three one-third width IT sleds comprises a non hot plug storage node placed between and functionally shared by two computing nodes, wherein the computing nodes are configured to continue operating during cold servicing of the non hot plug storage node.
