This section presents sizing examples for three indexers:
This example is a single node solution with 200 GB per day ingest, 30-day Hot/Warm retention, with 120-day or 365-day cold retention.
Calculate the storage required in this configuration as follows:
The disk write is:
The 30-day Hot/Warm configuration using 960 GB SSD disks requires:
Adding two disks to achieve RAID 6 yields six disks required. Since this configuration uses SSD disks, the IOPS exceed the minimum requirement.
The 120-day retention using 1.8 TB 10 K RPM SAS disks in a RAID 6 configuration is calculated as follows:
Adding two disks to allow for RAID 6 yields 9 disks required. The IOPS for this configuration is around 1050, which exceed the minimum requirement of 800 IOPS:
The 365-day retention Cold storage using 2.4 TB 10 K SAS disks in a RAID 6 configuration yields the following:
Adding two disks to allow for RAID 6 yields 18 2.4 TB 10 K RPM disks, exceeding the minimum of 800 IOPS:
This example is a single node indexer with 250 GB per day ingest, 30-day Hot/Warm retention, with 120-day or 365-day Cold retention.
Calculate the storage required for this configuration as follows:
The disk write rate is:
The 30-day retention Hot/Warm configuration using 960 GB SSD disks requires:
Adding two disks to achieve RAID 6 yields six disks required. Since this configuration uses SSD disks, the IOPS exceed the minimum requirement.
The 120-day retention using 1.8 TB 10 K RPM SAS disks in a RAID 6 configuration is calculated as follows:
Adding two disks to achieve RAID 6 yields 11 disks required. The IOPS for this configuration is around 1350, which exceeds the minimum requirement of 800 IOPS:
The 365-day retention Cold storage using 2.4 TB 10 K SAS disks in a RAID 6 configuration yields the following:
Adding two disks to allow for RAID 6 yields 22 2.4 TB 10 K RPM disks, exceeding the minimum of 800 IOPS:
This example is a single-node solution with 300 GB per day ingest, 30-day Hot/Warm retention, with 120-day or 365-day Cold retention.
Calculate the storage required for this configuration as follows:
365-day retention Cold
The disk write rate is:
The 30-day Hot/Warm configuration using 1.92 GB SSD disks requires:
Adding two disks to achieve RAID 6 yields a five disks required. Since this configuration uses SSD disks, the IOPS exceeds the minimum requirement.
The 120-day retention using 1.2 TB 10 K RPM SAS disks in a RAID 6 configuration is calculated as follows:
Disk file systems have a small overhead, so increase the total to 16 disks.
Adding two disks to allow for RAID 6 yields 18 disks required, each 1.2 TB 10 K RPM.
The IOPS for this configuration is around 2700, which exceeds the minimum requirement of 800 IOPS:
The 365-day retention Cold storage using 2.4 TB 10 K SAS disks in a RAID 6 configuration, which are calculated as follows:
Adding two disks to allow for RAID 6 yields 25 2.4 TB 10 K RPM disks, exceeding the minimum of 800 IOPS:
Due to disk slot restrictions, this solution does not meet the full 365-Day retention, and uses 23 2.4TB disks.
The R740XD requires a mid-plane disk area to allow for more than 24 disks.
