Nexenta / FreeNAS / Linux & ZFS Formular

sysGen offers a variety of high-quality enterprise storage appliances. Appliances can be integrated into an existing SAN without much effort as optimally configured storage servers.

sysGen Storage Appliances aim to provide small, medium and large enterprises, administrations and research institutions with a complete SAN solution that is easy and secure to install (also as a high availability solution), which corresponds to the range of functions and quality of extremely expensive appliances without completely restricting flexibility.

ARC Cache is the primary ZFS cache. Typically, 1GB of memory is reserved for the operating system, the remaining memory is used for ARC. With L2ARC the cache memory can be extended with SSDs.

L2ARC is a secondary read cache that extends the ARC cache. As soon as the ARC cache reaches its capacity limit, ZFS uses the secondary cache to improve the read performance. L2ARC is comparable to the CPU level 2 cache.

ZIL meets POSIX requirements for synchronous writes. Such drives are not absolutely necessary, but can significantly speed up the processing of writes in certain system situations. If no drives are configured, ZIL is moved to the slow main memory pool. sysGen recommends the use of two hard disks under RAID-1 (mirror). The size of the ZIL should not be more than half the size of the physical storage.

These drives are used for the main storage pool. ZFS configuration options:
MIRROR - Mirrors of a group of drives, multiple mirrors can be stripped, similar to a RAID-10.
RAID-Z - single parity with RAID-5 (one disk failure per vdev).
RAID-Z2 - double parity with RAID-6-(2 drive failures per vdev)
RAID-Z3 - triple parity (3 drive failures per vdev)
