It really depends...it's always about what you are trying to achieve and what design approaches your systems let you to deploy: as example consider the case where you have a VMware ESXi host with - say - just two ports (of the same NIC or of different NICs)...now you can (a) connect those two ports on the VSF (one port into VSF Member 1, the other one into VSF Member 2) and doing absolutely nothing VSF side or you can (b) play with Non Protocol aggregation (static, in HP jargon is Port Truning of type "trunk" and not "lacp") and, correspondingly, doing the same on the terminating ports on your VSF (trunk 1/A1,2/A1 trk100 trunk) or, finally, you can (c) play with LACP aggregation (also called dynamic) and, correspondingly, configuring terminating ports on your VSF to be of type lacp (trunk 1/A1,2/A1 trk100 lacp). The fact you're going to select (a), (b) or (c) really depends on what was configured Servers side and the amount of automatic resiliency you want into those links.
Consider that (a) - neither (b) or (c) (at least until you build a solution based on other virtualization technologies) - can be used against to separated switches, so where VSF is not a viable option.
This preamble to say that conditions varies.
Back on track...I will suggest to consider LACP Port Trunking VSF Side IF your Server Team can configure Ports Teaming/Bonding of type 4 (LACP IEEE 802.3ad) on your Servers...that way your servers will be dual homed (dual legged into) VSF Members...and the Link Aggregation Control Protocol will enhance resiliency (against port, cable, module, chassis, server NIC, server port) failures and will also improve the throughput (remember that usage of links in a Link Aggregation Group = Port Trunking is governed by the type - src/dst - of egressing traffic).
I have dozens of servers' aggregated connections plus uplinks/downlinks to other switches made through LACP Port Trunks (working with 2|3|4x1G or 2|4x10G ports) terminating on a VSF and no a single issue in years of flawless working (on the contrary...only benefits).
