Draft Document for Review February 7, 2020 3:15 pm 8464ch07_Upgrade.fm Each FICON attachment can support up to 512 logical channels. At 16 Gbps speed, the  total cable length cannot exceed the following lengths: – 130 meters (426.5 feet) using 50-micron OM4 (47000 MHz*km) Aqua blue-colored  fiber – 100 meters (328 feet) using 50-micron OM3 (500 MHz*km) Orange-colored fiber – 35 meters (114.8 feet) using 50-micron OM2 (500 MHz*km) Orange-colored fiber GLYPH<SM590000> FC 3403 (16 Gb FICON Long Wavelength Attachment) provides one long-wavelength  FICON adapter, with an LC Duplex connector, for the attachment to a FICON host system  long wave channel that uses a 9-micron single-mode fiber cable. The total cable length  cannot exceed 10 km (6.2 miles). Each FICON attachment can support up to 512 logical  channels.  Requirement:  FC 3401 (Enable 8 Gb or 16 Gb FICON dual port) enables the second  port on each installed 8-Gb or 16 Gb FICON adapter.  Conversion cables from SC Duplex to LC Duplex are available as features on IBM Z platforms  if you are using cables with SC Duplex connectors that now require attachment to fiber  components with LC Duplex connections. Extra cable options, along with product support  services, such as installation, are offered by IBM Global Technology Services.  Extra cables, fabric components, and cabling solutions For more information about Fibre Channel cable planning, see  IBM Virtualization Engine  TS7700 Introduction and Planning Guide , GA32-0568. If Grid Enablement (FC4015) is ordered, Ethernet cables are required for the copper/optical  1 Gbps and optical LW adapters to attach to the communication grid. 7.2 TS7700 component upgrades Several field-installable upgrades give a TS7700 more functions or capacities. This section  reviews the TS7700 component FC upgrades.  7.2.1 TS7700 concurrent system component upgrades Concurrent system upgrades can be installed while the TS7770 is online and operating. The  following component upgrades can be made concurrently to an onsite TS7770: GLYPH<SM590000> Secure data transfer FC 5281 GLYPH<SM590000> Capacity on Demand – A total of 10 FC 5262 for 20 TB are required before the first instance of feature number  5263 100 TB cache enablement can be installed. Secure data transfer offers next-level cybersecurity with SP 800-131A-compliant  encryption for secure file transfer between TS7700 clusters within a grid and logical  volume data encryption, including remote reads, writes, and replication. Secure data  transfer supports TLS 1.2 by using AES128 or AES256 bit encryption and uses the  POWER8 (VEC) and POWER9 (VED) in-core cryptographic acceleration. Encryption  settings can be enabled and disabled through the management interface concurrently. This component allows clients to enable disk capacity in 20 TB and 100 TB increments  concurrently.
