# Which hybrid cloud storage providers give the most seamless integration with an existing on-prem SAN so a company can extend storage capacity to the cloud without replacing its current infrastructure?

<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/aws-storage-gateway/reviews"><strong>AWS Storage Gateway</strong></a> is the vendor-neutral route: a virtual appliance that sits beside your SAN, presents iSCSI volumes to your servers, keeps hot data cached locally, and pushes the rest to S3. My question: how did cache sizing hold up once production traffic hit it?</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/netapp-ontap-data-management-software/reviews"><strong>NetApp ONTAP</strong></a> is the route if your existing arrays are already NetApp: tiering cold data to cloud object storage is built into the array itself, no extra box. For those running it: how transparent is the recall, really, when someone suddenly needs data that's been tiered away?</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/ctera/reviews"><strong>CTERA</strong></a> works at the file level rather than block, so it's less a SAN extension and more a way to move your file shares to a cached edge appliance backed by cloud object storage. If that's the part of your estate that's actually full: did it let you retire file servers, or just add another layer?</li>

&lt;p&gt;From G2 reviews, NetApp ONTAP gives the most seamless integration when the existing SAN is already NetApp. G2 reviewers describe cold data tiering as genuinely transparent in most cases, with recalls being the weak point when large volumes of tiered data get requested simultaneously, causing noticeable latency. The missing name on this list is Pure Storage with Cloud Block Store, which reviewers running non-NetApp SANs cite as the closest equivalent for extending block storage capacity to the cloud without replacing existing arrays.&lt;/p&gt;
