The Kernel and Driver development team owns Linux and VMware initiator stack behavior along with Fibre Channel and NIC drivers on the Pure storage array, working across storage area network protocols such as Fibre Channel and Ethernet. This role leads a group of engineers doing kernel and driver development, debugging initiator and protocol issues, maintaining Purity's FCP target driver and NIC drivers, upstreaming fixes to Linux, and optimizing FlashArray attachment performance.
What you will do
- Working for a team that deals primarily in various storage area network protocols such as Fiber Channel and Ethernet.
- On the initiator side, the team will be responsible for Linux initiator behavior attached to Flasharray. Focus is on NVME (ROCE, FC, TCP/IP) but also includes FC-SCSI (FCP) and iSCSI interfaces. This includes software development/fixes for Linux initiator stack, debugging initiator problems, and creating compatibility documents for Purity. For VMWare, focus is on debugging issues with VMWare as an initiator, and creating compatibility documentation.
- For FibreChannel and NIC Drivers, focus is responsibility for FC-SCSI driver stack for storage side and responsibility for NIC drivers on networking side. This includes responsibility for related code, utilities, enhancements supporting RAS, as well as debugging failures found internally and in the field.
- Maintain Linux kernels for internal testing
- Documenting supported configurations for customers
- Responsibility for evaluating Linux initiator behavior and optimizing for Pure Storage Flasharray. This includes correctness as well as optimizing for performances.
