This means that each drive has two SAS paths via two separate backplane modules. It also means that Apocalypse requires dual-ported SAS drives in order to take advantage of the redundant paths. There are a total of four SAS connectors on the back. The bottom two are redundant connections to the front SAS backplane and the top two are redundant connections to the rear SAS backplane. ## Population The Apocalypse array contains the following disk groups: * 11 2-terabyte 7.2k rpm Seagate ST2000NM0023 drives (forms the second Apocalypse vdev) * 11 1-terabyte 7.2k rpm Seagate ST1000NM0001 drives (forms the first Apocalypse vdev) * 4 6-terabyte 7.2k rpm HGST HUS726060AL4210 drives * 6 900-gigabyte 10k rpm Western Digital WD9001HKHG-02VUC drives 3 200-gigabyte HGST HUSMM1620ASS200 solid state drives (currently unused) ## Harddrive WWIDs Below are the WWIDs for each of the HDDs installed in Apocalypse. If a drive fails, the below table can be used to identify the location of the failed drive and replace it. ### Front | | | | | | ---------------- | ---------------- | ---------------- | ---------------- | | 5000C50055DF0F1C | 5000C50055DF9D44 | 5000C50042012E70 | 5000C500558C5A0C | | 5000C500420343AC | 5000C50042012F1C | 5000C500558C64B8 | 5000C500420A3408 | | 5000C500420A3284 | 5000C500420A0920 | 5000C500420139FC | 50000C0F0119C010 | | 50000C0F0115E6F0 | 50000C0F01B6D988 | 0PY13ZGA | 50000C0F0119C014 | | 50000C0F01BE7CDC | 50000C0F01B6D20C | 0PY13LZA | 0PY13M1A | | 5000cca24260ef7c | 5000cca242623e88 | 5000cca2425ff9d0 | 5000cca242623d40 | ### Back | | | | | | -------------- | ----- | ----- | ---------------- | | Power Supplies | Blank | Blank | Blank | | Power Supplies | Blank | Blank | Blank | | Power Supplies | Blank | Blank | Blank | | Blank | Blank | Blank | Blank | | Blank | Blank | Blank | 5000C50056032227 | | Blank | Blank | Blank | Blank | --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://documentation.tjhsst.edu/obsolete/apocalypse.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
