Hello Eugene, AFAIK you can split each one of the twenty four central QSFP+ 40G interfaces (from interface 1/0/5 included to interface 1/0/28 included) into 4x10G SFP+.
For a short length (say < 5 meters) you can use DAC Breakout cables with QSFP-type connector on one end and four SFP-type connectors at the other end or, if length is a little bit longer (with restrictions), you can use Fiber breakout cables instead.
I don't see any option to solve your requirement of 1G/10G copper interfaces on the JL579A.
One solution would be to connect a secondary 1G/10G Switch to your Aruba 8320 and use interfaces on that additional switch to connect edge devices working at lower speeds...not the best solution, I know...but, OTOH, you need to consider that your Aruba 8320 JL579A fits ToR/Core positions where 1G/10G copper interfaces are probably seen less frequently than higher speed ones like 25G/40G/100G so you can't blame that the Aruba 8320 doesn't support 10G copper or 1G copper on 40G interfaces.
As reference, please have a look at

Subject: JL579A Aruba 8320 32p 40G QSFP+ to 10GB/1GB Transceiver Question
I have a JL579A Aruba 8320 32p 40G QSFP+
I have some network devices that I need to connect to the switch directly that are:
1. 1GB copper
2. 10GB copper
3. 10GB-SR4 (LC) Fiber
The switch itself only has QSFP ports and it looks like in the 8320 datasheet, there are only 40GB QSFP transceivers. I see 1/10GB transceivers are listed but is there anyway to connect them to the switch?
datasheet: https://www.arubanetworks.com/assets/ds/DS_8320Series.pdf
I found a possible solution of using e JH231A (HPE X142 40G QSFP+ MPO SR4 Transceiver and using a breakout cable for a scenario for my 3rd connection.
