GLYPH<SM590000> Each DS8886F and DS8886 CPC can have 8 - 24 processor cores, and 64 - 1,024 GB of  processor memory, for 128 GB - 2048 GB of total system memory. GLYPH<SM590000> Each DS8884F and DS8884 CPC has 6 - 12 processor cores and can have 32 - 128 GB  of processor memory, for 64 GB - 256 GB of total system memory. 28  IBM DS8880 Architecture and Implementation Note:  The IBM DS8882F Rack Mounted system has several hardware components that  slightly differ from those presented here, and is covered in detail in the IBM Redbooks  publication  Introducing the IBM DS8882F Rack Mounted Storage System , REDP-5505. This section presents the current DS8880 configurations and models. The DS8880 storage  systems are associated with machine type 283x for Hybrid family, or 533x for All-flash family  models. The last digit of the machine type corresponds to the length of warranty option  chosen, where  x  equals the number of years. DS8880 offers a one-year, two-year, three-year,  or four-year warranty period. Expansion frames must have the same machine type as the  base frame. The main variations between models are the combinations of CPCs, I/O  enclosures, storage enclosures, disks, and direct current uninterruptible power sources  (DC-UPSs). Note:  The DS8884, DS8884F, DS8886, DS8886F, and DS8888F hardware platforms are  specific to each configuration. Upgrades are not supported from one hardware platform to  another. Upgrades from the smallest to the largest configuration in terms of system memory,  processors, storage capacity, and host attachment can be performed concurrently.  Similar to earlier generations of the IBM DS8000 series, the DS8880 consists of one base  frame, and optional expansion frames. The CPCs reside in the base frame, and can be  upgraded with additional processor cores and system memory to accommodate growing  performance, or when additional storage capacity or host connectivity is required. Both CPCs in a DS8880 system share the system workload. The CPCs are redundant, and  either CPC can fail over to the other CPC if a failure occurs, or for scheduled maintenance or  upgrade tasks. The CPCs are identified as CPC 0 and CPC 1. A logical partition in each CPC  runs the AIX V7. x  operating system and storage-specific LIC. This logical partition is called  the  storage node . The storage servers are identified as  Node 0  and  Node 1  or  server0  and server1. 2.2 DS8880 configurations and models
