5/31/2023 0 Comments Software raid monitorNow, if I’m misunderstanding and you actually want two independent RAID 0 arrays, what I’m about to say, still applies in all circumstances. If you want maximum redundancy and performance you’ll need RAID 10 which comes at the largest cost because you can only use half the storage space available on the physical disks. ![]() They are both different than RAID 5 which is striping w/ parity. The two modes are different but essentially the same. What you describe….Two RAID 0 arrays where one backs up the other is called RAID 0+1 or RAID 10. Maybe there’s a little misunderstanding of RAID. What am I overlooking here? Is there something better to do with the 4 SSDs in terms of external storage? ![]() It somehow seems fishier to me, but the overall usable capacity would be larger. I guess I could also put the four SSDs into a RAID 5 array of about 12TB, where one drive could get damaged, but the array rebuild with a new one. I'd need to backup the mac to a third external drive, to be able to restore the system and thus software RAID setup and configuration? On the other hand, if the internal storage of my mac gets somehow corrupted or wiped, the software raid also goes out the window and the data is lost. I don't want a NAS for various reasons!Īs I understand it, if at one point the enclosure goes somehow bad and doesn't damage the drives in the process, the latter could still be transplanted into another enclosure, and used without needing to rebuild the array, right? The arrays would be managed with software, either Disk Utility, SoftRAID, or something else. OWC Thunderbay Mini), and buy two more 4TB SSDs to make two RAID 0 arrays of 8TB each: one would be for storage and the other for backing up the first. My plan is to get an external Thunderbolt enclosure with a minimum of 4 bays and no hardware RAID (e.g. Color-coded icons depict switch and interconnection status.įor in-depth storage monitoring, download OpManager - the comprehensive storage monitoring tool.I currently have two 2.5" 4TB SSDs.Link details table shows link name, source, and destination.Topological map shows arrays and their connections to switches and host servers.You can visually see the utilization of components like LUN volumes and take preventive measures as they reach their peak capacities Visualization Storage array capacity - Total / Configured / Used / Free.The parameters collected include the following , Performance statistics are computed at periodic intervals and reports generated to provide trend analysis for the storage array components like You can generate the reports for various time periods such as today, yesterday, last N days, last week, this month, last month, and between two selected days Performance Reports Escalates unattended alarms to higher ups based on pre-defined rulesĪvailability reports on RAID controllers and its ports show the availability trends, downtime history, MTTR, MTBF, etc.Reports alarms to administrators through email or SMS messages based on customizable rules.Management functions such as assign owner, annotate, clear, and delete.Captures Storage Array & Component Status Change Notifications.SNMP traps from the arrays are also captured and appropriate alarm is generated. Early indications are provided on hardware/software problems and alarms are generated on drive failures, sensor faults such as Fan Failure, Battery Failure, Power supply failure. ![]() OpManager periodically polls the devices to check the health, availabiity, and utilization of storage RAIDs. Device level problem report filing and maintenance.Comprehensive physical and logical asset details in RAIDs.Administrators can key in details such as device location, vendor details, and technical support info.A complete and comprehensive list of vendor specific supported features are provided in inventory page details and supported performance monitors. The above table lists the features supported by OpManager for storage devices.
