Intel® Server Board S2600WF Product Family Technical Product Specification
55
6. System I/O
The server board input/output features are provided via the embedded features and functions of several
onboard components including: the Integrated I/O Module (IIO) of the Intel® Xeon® processor, the Intel®
C620 series chipset (PCH), and the I/O controllers embedded within the Aspeed* AST2500 management
controller. See Figure 12 for an overview of the features and interconnects of each of the major sub-system
components. Server board I/O features include:
• Intel® QuickAssist Technology (Intel® QAT) support (S2600WFQ only)
• PCIe* riser card and add-in card support
• Intel® Ethernet Network Adapter for OCP* support
• Intel® Integrated RAID Module support
• Onboard storage subsystem
• External I/O port support
6.1 Intel® QuickAssist Technology (Intel® QAT) Support
This section provides a high level overview for Intel QAT and its support on the Intel® Server Board S2600WF
product family. For more information about this technology, visit

.
Note: For the Intel Server Board S2600WF product family, only the S2600WFQ SKU supports Intel QAT.
Intel QAT provides security and compression acceleration capabilities used to improve performance and
efficiency across the data center.
Intel QAT supports the following:
• Cryptographic capabilities: 100 Gb/s IPSec & SSL
o Symmetric ciphers: (AES, AES-XTS, 3DES/DES, RC4, Kasumi, Snow3G, ZUC)
o Message digest/hash (MD5, SHA1, SHA2, SHA3)
o Authentication (HMAC, AES-XCBC)
o Authenticated encryption (AES-GCM, AES-CCM)
• Asymmetric (public key) cryptographic capabilities
o Modular exponentiation for Diffie-Hellman (DH)
o RSA key generation, encryption/decryption and digital signature generation/verification.
RSA(2K Keys) up to 100K Ops/sec
o DSA parameter generation and digital signature generation/verification
o Elliptic curve cryptography: ECDSA, ECDH
• Compression/decompression (deflate) up to 100Gb/s
On the Intel Server Board S2600WFQ, there are three Intel QAT engines incorporated into the Intel C628
chipset with a dedicated x16 PCIe* 3.0 link that allows for up to 100 Gbps aggregated bandwidth.
Intel QAT bandwidth can be increased to 150 Gbps with the addition of an optional Intel QAT bridge cable
connected between the onboard mini-SAS HD connectors for SATA Ports 0-3 and 4-7, and two of the
onboard PCIe x4 OCuLink connectors as shown in Figure 28.
