Notes and Tuning
<> Failover is supported by an additional Celerra 514 Data Mover that operates in
<> standby mode. In the event of a Data Mover failure, this unit takes over the
<> function of the failed unit. The standby Data Mover does not contribute to
<> the performance of the system and is not included in the processor, memory,
<> or other components listed above.
<>
<> Server tuning:
<> param ufs inoBlkHashSize=170669 (inode block hash size)
<> param ufs inoHashTableSize=1218761 (inode hash table size)
<> param ufs updateAccTime=0 (disable access-time updates)
<> param nfs withoutCollector=1 (enable NFS-to-CPU thread affinity)
<> param file prefetch=0 (disable Dart read prefetch)
<> file initialize nodes=980000 dnlc=1056000 (Number of inodes, number of
<> dynamic name lookup cache entries)
<> nfs start openfiles=722462 nfsd=4 (no. of open files and 4 NFS daemons)
<> param kernel outerLoop=8 (8 consecutive iterations of network packets processing)
<> param kernel maxStrToBeProc=16 (no. of network streams to process at once)
<> ians cge0 packetburst=16 (maximum no. of packets to be processed at once)
<> ians cge1 packetburst=16 (maximum no. of packets to be processed at once)
<>
<> Storage array notes:
<> The DMX1000-P used for storage exposes LUNs across multiple Fibre ports.
<> Each LUN is 11499MB in size and resides on a single disk. Four of the
<> fibre ports are connected to the Fibre switch and zoned along with the two
<> ports on the node. The filesystem is built on a stripe that spans across
<> the filesystem LUNs.
<> DMX1000-P was configured with 32GB memory. The memory is backed up with
<> sufficient battery power to safely destage all cached data onto the disk
<> in the event of a power failure.
<>
<> Client tuning:
<> ndd -set /dev/tcp tcp_recv_hiwat 65536
<> ndd -set /dev/tcp tcp_xmit_hiwat 65536
<> ndd -set /dev/tcp tcp_cwnd_max 2097152
<> ndd -set /dev/tcp tcp_max_buf 4194304
