Inside an Object First Ootbi 2U node
In the Object First Ootbi 2U appliance range, the 18 to 216 TB models use an eleven-drive RAID 6 array of 2, 4, 8, 16 or 24 TB drives with one hot spare; the 432 TB model uses 22 × 24 TB drives in RAID 60 with two hot spares[src]. The operating system lives on two 480 GB M.2 NVMe drives in RAID 1 on a BOSS card, so it never shares disks with backup data[src]. The NVMe cache is 800 GB on the 18 and 36 TB models and 1.6 TB on everything larger[src].
Building a cluster of up to four nodes
Beyond one cluster, Object First adds clusters as separate extents of a Veeam Scale-Out Backup Repository, which is how it quotes capacities beyond 7 PB[src]. Nodes can also be removed: the release notes describe a node-removal process that cleans up repository data as it goes[src].

From Object First's appliance datasheet (1.1_20260116). All listed network interfaces are included; two ports are active at a time and both must be the same type[src]. The OS is Object First's custom hardened Linux on every model, and the storage protocol is S3[src].
What the site needs to be ready
Three IPs for the first node
Two switches for redundancy
Port 443 and time services
iDRAC or keyboard and monitor
2U, depth and clearance
Veeam 12 or later

Get an Ootbi 2U appliance sized and quoted
- We work out usable capacity from your data, change rate, retention and immutability period, then pick the node size.
- We compare one 432 TB node against several smaller ones for ingest, Instant Recovery and growth.
- We check rack depth, power, switch ports and the outbound ports Ootbi needs.
- We quote the appliance, any extra nodes and Object First support together.
Object First Ootbi 2U: common questions
What capacities does the Ootbi 2U appliance come in?
Six: 18, 36, 72, 144, 216 and 432 TB usable per node. The first five are eleven-drive RAID 6 arrays of 2, 4, 8, 16 or 24 TB drives plus one hot spare; the 432 TB model is 22 × 24 TB drives in RAID 60 plus two hot spares, in a deeper chassis.
Why is the 432 TB Ootbi faster than the 216 TB?
Object First does not give a reason, but the 432 TB node has twice the drives, in RAID 60, and Object First rates it at up to 2 GB/s ingest and 45 concurrent Instant Recovery VMs, against 1 GB/s and 20 VMs for every model from 18 to 216 TB. In exchange it draws more power (620 W backing up against 490 W) and is 87.3 cm deep rather than 72.2 cm.
Can different Ootbi capacities be mixed in one cluster?
Yes. Object First says node capacities can be mixed and matched in a cluster of up to four nodes, and that adding a node needs no change to the Veeam repository or namespace. Four 432 TB nodes are the 1.7 PB maximum; four of the smaller models reach 864 TB.
How many IP addresses does an Ootbi need?
Object First says configuration needs three IP addresses, a username, a password and MFA set up: one for each of the two data interfaces and a virtual cluster IP on the same subnet, which Veeam uses as its service point. Each additional node needs two more addresses for its own data interfaces. An iDRAC port for remote console access takes one more if you use it, and should be restricted or disabled once the system is running.
Does Ootbi need internet access?
Object First’s installation guides list outbound HTTPS on port 443 for updates, support and telemetry, plus NTP (UDP 123) and NTS (TCP 4460) for time. Object First’s setup checklist also asks for internet access during initial setup, for a first required update. Telemetry is optional on a CapEx appliance but mandatory on the Consumption model, which stops accepting new backups after a grace period without it. An offline update bundle exists for sites that cannot reach the internet.
Is the usable capacity before or after RAID?
After. The published capacity of each model works out as nine data drives’ worth per eleven-drive RAID 6 group: 9 × 24 TB = 216 TB, and two groups of 9 × 24 TB = 432 TB. The rest of the raw disk goes to parity and hot spares, about a quarter of it on every model.
What is in the box?
For the 2U appliance Object First lists the appliance, power cables, a rail kit, a wrist strap and the installation guide; the smaller models add a front bezel. M5 thumbscrew locks are optional and not included. The 432 TB model weighs 46.3 kg, and Object First suggests a multi-person lift or a rack platform.
