It&#x27;s always great to see storage hardware being opened up, thanks Backblaze.<p>I have a question after reading the Vault overview here:<p><a href="https:&#x2F;&#x2F;www.backblaze.com&#x2F;blog&#x2F;vault-cloud-storage-architecture&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.backblaze.com&#x2F;blog&#x2F;vault-cloud-storage-architect...</a><p>I&#x27;m curious what the bandwidth demand is when an entire host fails and you have to drop a new replacement host in, since you would have 60 Tomes in the Vault that need to be rebuilt at once. You have at least two other parity copies when a host dies (assuming no other drives in the affected host&#x27;s Tomes are dead on other hosts in the Vault set), so I&#x27;m guessing you can afford to wait the handful of days it would take to rebuild the host. I&#x27;m still curious to know what rebuild speed you plan for, since I&#x27;m guessing you&#x27;d be looking at 40Gbps NICs eventually. I was surprised to see only 2x10Gbps.
