我想问一下Nutanix是否支持更换不同容量的SSD/HDD。
我问这个问题的原因是,我想在数据增长而不增加计算容量时保持一定的Hot Data比率。
我担心的是,如果我只添加NX-6035C就可以增加我的数据,但SSD可能不足以维持所需的Hot data的比例。
谢谢。

\n1 - SSD Tier size concerns when adding cold nodes
\nRarely does the size of an applications working set just \"go up\" arbitrarily, and even when it does, it usually translates into additional CPU and memory being needed to address more and more resources.
\n
\nWe haven't seen many if any issues when adding cold nodes strictly for the sake of capacity, as that is their purpose, simply adding more cold storage.
\n
\nIf you're application is growing, you'd very likely need to buy more \"regular\" nodes anyways, which would increase the size of all resources.
\n
\n
\nThat said, there could be some corner cases in which you do have physical GB capacity going up, and working set size (hot data) going up, and not need anymore compute.
\n
\nTo this end, a future release is going to let you add ANY node as a \"cold\" node, such that you could have an \"all flash\" storage only node, to JUST increase the size of the SSD tier.
\n
\n2 - Replace Drive in a node with a different capacity
\nWhile we dont advertise it, we have done this plenty of times as the situation arises. Ideally, we get the sizing correct upfront, so this isn't needed, but we've done this \"tactically\" with customers. This isn't something I'd plan on having to do on a regular basis if I were you.","className":"post__content__best_answer"}">
