ESOS - Enterprise Storage OS

Enterprise Storage OS is a quasi Linux distribution based mostly on the superb SCST venture; its function is to offer SCSI targets by way of a suitable SAN (Fibre Channel, InfiniBand, iSCSI, FCoE). In a nutshell, ESOS® can simply flip a server with the appropriate hardware right into a disk array that sits in your enterprise Storage Space Network (SAN) providing sharable block-level storage volumes.

Typical makes use of for an ESOS® “storage server” embrace VMFS datastores on VMware ESX/ESXi, Windows NTFS volumes, Linux disks, and so forth. A excessive efficiency, purpose-built (appliance like) Linux base constructed from scratch, with no relation to other Linux distributions.

  • ESOS is reminiscence resident — it boots off a USB flash drive, and the whole lot is loaded into RAM. If the USB flash drive fails, ESOS® will ship an alert e mail, and you may simply construct a brand new ESOS® USB flash drive, then exchange the failed drive and sync the configuration.
  • Kernel crash dump seize help. If the ESOS® Linux kernel occurs to panic, the system will reboot right into a crash dump kernel, seize the /proc/vmcore file to the esos_logs file system, and eventually reboot again into the manufacturing ESOS® kernel — all mechanically. ESOS® sends an e mail alert on system start-up and checks for any crash dumps.
  • Two working modes: Production (default) & Debug. With “Production” mode, the efficiency model of SCST (make 2perf) is used. In case you discover you’re having an issue and never getting adequate diagnostic logs, merely reboot into “Debug” mode (full SCST debug build, make 2debug) and get further log knowledge.
  • Enterprise RAID controller CLI configuration tools. Fashionable RAID controller CLI tools are an non-compulsory set up with ESOS® (eg, LSI MegaRAID, Adaptec AACRAID, and so on.) which permits configuration (add/delete/modify) of volumes / logical drives from a operating ESOS® system.
