| 5 | A [wiki:GENIGlossary#Aggregate GENI aggregate] provides resources to GENI experimenters. There are different types of aggregates. Some aggregates such as [wiki:GENIRacksHome GENI Racks] provide compute and network resources available, some such as [wiki:GeniAggregate/I2AL2S AL2S], [wiki: GeniAggregate/I2ION ION] and [wiki:GeniAggregate/MAX MAX] provide wired network resources and others such as [wiki:GeniAggregate/NYUWiMAX NYU WiMAX] and [wiki:GeniAggregate/OrbitWirelessTestbed Orbit] provide wireless resources. For a list of all GENI aggregates, see [wiki:GeniAggregate#ListofGENIaggregates list of aggregates]. |

| 7 | == Picking aggregates == |
| 8 | |
| 9 | You may want to take the following into consideration while picking aggregates for your experiment: |
| 10 | * ''Aggregate type.'' The most widely deployed GENI resources are [wiki:GENIRacksHome#InstaGENIRacks InstaGENI] and [http://groups.geni.net/geni/wiki/GENIRacksHome#ExoGENIRacks ExoGENI] racks that provide compute and networking resources. Look [wiki:#RackDifferences here] for major differences between these two rack types. |
| 11 | * ''Aggregate location.'' The geographical coordinates of aggregates can be found in their advertisement [wiki:GENIGlossary#RSpec RSpecs]. |
| 12 | * ''Support for stitching.'' Aggregates that support [wiki:GeniNetworkStitching GENI stitching] are listed at [wiki:GeniNetworkStitchingSites GENI network stitching sites]. |
| 13 | * ''Virtual machine vs. raw-PC''. Most racks provide virtual machines and raw-PCs. As far as possible you should use virtual machines as they are many more of them and your resource reservation is more likely to succeed. |
| 14 | * ''Resource availability.'' Some aggregates are more heavily loaded than others. For current usage information on InstaGENI racks, see [wiki:ExpGraphs]. |
| 15 | |
| 16 | == Resource expiration == |
| 17 | GENI [wiki:GENIGlossary#Slice slices] and the resources allocated to your slice (called [wiki:GENIGlossary#Sliver slivers]) have expiration times associated with them. You can extend this expiration using experimenter tools such as Omni, the GENI Portal or the GENI Desktop. Note that: |
| 18 | * Sliver expiration times cannot go beyond the slice expiration times. So be sure to extend the slice expiration time before you extend the sliver expiration time. Some tools such as the GENI Portal allow you to extend slice and sliver expiration at the same time. |
| 19 | * Different aggregates have different initial expiration times and allow you to extend resources by different amounts of time. See the table at [wiki:GENIResources#ExpirationbyAggregatetype] for initial and max expiration times allowed by different aggregates. |
| 20 | |
| 21 | == Aggregate categories == |
| 22 | GENI aggregates are categorized as follows. You can select aggregate by category in tools such as the GENI Portal. |
| 23 | * ''GENI Production.'' Resources tested and operated using GENI processes and procedures, under the GENI Aggregate Provider Agreement. Maintenance outages are typically scheduled and announced on the experimenter-ops mailing list. GENI Production aggregates are listed in the [wiki:GENIProduction GENI Production Resources] page. |
| 24 | * ''GENI Experimental.'' Resources used for early deployment of new features and may not have completed testing. Outages are likely to be more frequent and may not be scheduled or announced. |
| 25 | * ''Other Federated.'' Resources made available by agreement with GENI partner organizations, including international partners. They are operated under their own policies and procedures. |
