VxRAIL architecture - Physical

1.how servers communicate with drives

2. is there any back pane between drives & servers, if yes one common interface or each server has different ? is this back pane redundant ?

3.What if any Nic of any servers fails is it whole appliance down situation or just one server ? same of rest of the components, which component in single node will lead to complete appliance down ?

4. why we need to have all 8 ports connected be it on a single swithc or 2 switch to make appliance up ?

5. both 10G ports active active or active passive ? if active active then why only one vmnic is enabled ?

6. If host-1 goes down which host the vCenter/PSC/VxRAIL Manager along with Prodcution VM's what happens when HOST-1 goes down ? Only management is unavailable or Production VM's will also wont move ?

7. Can vCenter VM/PSC/VxRAIL Manager will vMOtion in event of host 1 down ?

8. How does Erasure coding differ from RAID, and how  33% space is used in EC1 even when it is as good as RAID-5 ?

9. How do you define no. of IOPS on per system ?

10. Marvin & Loudmouth service use,functionality and dependencies ?

11.Why only IPV6 multicast required for Management traffic ?

12. VxRAIL Manager has graceful shutdown option, will this reboot all host or just the VxRAIL appliance cluster ?

If there is any alert (for ex. drive not accessible) Graceful shutdown doesn't allow to shutdown, then what is way out ?

13. When trying to SCP any VM from customer's external host , if fails due to permission issue , why ?

14. Created a folder under Marvin Data store, SCP VM from external host, if worked, but when tried multiple VM SCP in same folder, it failed " no space left" where as total space available is 9TB , data trying to copy is 2 TB, any resolution to this ?

15. Tried copy 2TB VM , it worked, so we can't copy directly to host, we copy on Marvin data store which has 1 drive (3.84)from each host so how does this copy works, block are written sequentially to all host one by one or all data first goes to node 1 drive 1 and if it fills then move to second node drive 1 ?Jeremy.MerrillVxRail Appliance
