(Consufused) Synergy 12000 with Virtual Connect SE 100Gb F32 Module

[BauNguyen]

Hi All,

I'm planning for a new Synergu 12000 system. with VC SE 100Gb F32 module.

I want to have 2 VCs in 12000 chassis for Ethernet and FC storage connections: 4 x 10G Ethernet & 4 x 16G FC Storage on each VC SE 100Gb F32 module.. So, I choose the part for that like this:

Chassis with VC SE 100Gb F32

Qty    Chassis
1        HPE Synergy 12000 Configure-to-order Frame with 10x Fans
2        HPE Virtual Connect SE 100Gb F32 Module for Synergy
8        HPE BladeSystem c-Class 10Gb SFP+ SR Transceiver
8        HPE QSFP28 to SFP28 Adapter
2        HPE Synergy 4-port Frame Link Module
1         HPE 6x 2650W Performance Hot Plug Titanium Plus FIO Power Supply Kit
2        HPE Synergy Composer2 Management Appliance
8        HPE 16Gb SFP+ Short Wave 1-pack Commercial Transceiver
6        HPE C19 - C20 WW 250V 16Amp 2.5m Jumper Cord
2        HPE 100Gb QSFP28 to QSFP28 3m Direct Attach Copper Cable
1         HPE BladeSystem c-Class 10GbE SFP+ to SFP+ 3m Direct Attach Copper Cable

Blade 480c

Qty    Blade
1        HPE Synergy 480 Gen10 Configure-to-order Compute Module
1        Intel Xeon-Gold 6230 (2.1GHz/20-core/125W) FIO Processor Kit for HPE Synergy 480/660 Gen10.
1        Intel Xeon-Gold 6230 (2.1GHz/20-core/125W) Processor Kit for HPE Synergy 480/660 Gen10
10      HPE Synergy 32GB (1x32GB) Dual Rank x4 DDR4-2933 CAS-21-21-21 Registered Smart Memory Kit
2        HPE 480GB SATA 6G Mixed Use SFF SC SE5031 SSD
1        HPE 96W Smart Storage Lithium-ion Battery with 260mm Cable Kit
1        HPE Smart Array P204i-c SR Gen10 (4 Internal Lanes/1GB Cache) 12G SAS Modular Controller
2        HPE Synergy 4820C 10/20/25Gb Converged Network Adapter

But I've confused about the QSFP28 to SFP28 Adapter to plug in VC SE 100 F32 module, is it correct, and do I have to add anything (like cable, DAC, breakout adapter,..) ?, and I choose 2 CNA 4820C in Blade 480c for Ethernet and FC Storage (one in each other) is correct or not.

Can somebody help me.

Thank you all for reading,

Hi BauNguyen,

Glad to know that you are planning for the new Synergy equipment.

Here are the details that should help:

QSFP28 is a hot-pluggable transceiver module designed for 100G data rate. QSFP28 integrates 4 transmit and 4 receiver channels. “28” means each lane carries up to 28G data rate. QSFP28 can do 4x25G breakout connection, 2x50G breakout, or 1x100G depending on the transceiver used.

SFP28 stands for Small Form-Factor Pluggable 28. It is the third generation of the SFP interconnect systems designed for 25G performance per the IEEE 802.3by specification (25GBASE-CR). The SFP28 is an enhanced version of SFP+, but is designed for 25G signal transmission.

The Virtual Connect SE 100Gb F32 Module for Synergy supports the following connectivity options to upstream switches >
- 100Gb to 100Gb link
- 100Gb to 4x 25Gb split links
these needs the QSFP25 as links are either 100Gb or 25Gb
This VC interconnect is also backward compatible with 40Gb switches. Supported options are >
- 40Gb to 40Gb link
- 40Gb to 4x 10Gb split links
these needs SFP+ as links are either 40Gb or 10Gb

Now, depending on the connectivity type (ethernet or FC), you will need to choose the SFP or DAC options.
Note : If you use splitter type connectivity, all 4x ports for the Q port must be of the same type. We cannot mix ethernet & FC on the subports of a Q port.
Hence, you will need to use 1x or more Q port for ethernet & 1x or more Q port for FC depending on the expected i/o, and connectivity type available at your upstream switches.

Refer to this link for the various types of supported SFPs + DACs available:
https://h20195.www2.hpe.com/v2/getdocument.aspx?docname=a00067745enw

Also, you do not need to get 2x of CNA 4820C for each server, as these are 'converged network adapters'. These basically combines the functionality of a host bus adapter (HBA) with a network interface controller (NIC) in a single device. At the OS level the functions are separated and network + HBA ports are detected separately.

Thanks for your interest in the Synergy solution.
