Back at the end of January, DataCore announced the availability of a new product called SANsymphony-V. This product replaces SANmelody in their product line, and is the first step in the eventual convergence of SANmelody and SANsymphony into a single product with a common user interface.
We’ve been playing with SANsymphony-V in our engineering lab, and our technical team is impressed with both the functionality and the new user interface – but that’s another post for another day. This post is focused on the packaging and pricing of SANsymphony-V, which in many cases can come in significantly below the old SANmelody pricing.
First, we need to recap the old SANmelody pricing model. SANmelody nodes were priced according to the maximum amount of raw capacity that node could manage. The full-featured HA/DR product could be licensed for 0.5 Tb, 1 Tb, 2 Tb, 3 Tb, 4 Tb, 8 Tb, 16 Tb, or 32 Tb. So, for example, if you wanted 4 Tb of mirrored storage (two 4 Tb nodes in an HA pair), you would purchase two 4 Tb licenses. At MSRP, including 1 year of software maintenance, this would have cost you a total of $17,496. But what if you had another 2 Tb of archival data that you wanted available, but didn’t necessarily need it mirrored between your two nodes? Then you would want 4 Tb in one node, and 6 Tb in the other node. However, since there was no 6 Tb license, you’d have to buy an 8 Tb license. Now your total cost is up to $21,246.
SANsymphony-V introduced the concept of separate node licenses and capacity licenses. The node license is based on the maximum amount of raw storage that can exist in the storage pool to which that node belongs. The increments are:
- “VL1” – Up to 5 Tb – includes 1 Tb of capacity per node (more on this in a moment)
- “VL2” – Up to 16 Tb – includes 2 Tb of capacity per node
- “VL3” – Up to 100 Tb – includes 8 Tb of capacity per node
- “VL4” – Up to 256 Tb – includes 40 Tb of capacity per node
- “VL5” – More than 256 Tb – includes 120 Tb of capacity per node
In my example above, with 4 Tb of mirrored storage and 2 Tb of non-mirrored storage, there is a total of 10 Tb of storage in the storage pool: (4 x 2) + 2 = 10. Therefore, each node needs a “VL2” node license, since the total storage in the pool is more than 5 Tb but less than 16 Tb. We also need a total of 10 Tb of capacity licensing. We’ve already got 4 Tb, since 2 Tb of capacity were included with each node license. So we need to buy an additional six 1 Tb capacity licenses. At MSRP, this would cost a total of $14,850 – substantially less than the old SANmelody price.
The cool thing is, once we have our two VL2 nodes and our 10 Tb of total capacity licensing, DataCore doesn’t care how that capacity is allocated between the nodes. We can have 5 Tb of mirrored storage, we can have 4 Tb in one node and 6 Tb in the other, we can have 3 Tb in one node and 7 Tb in the other. We can divide it up any way we want to.
If we now want to add asynchronous replication to a third SAN node that’s off-site (e.g., in our DR site), that SAN node is considered a separate “pool,” so its licensing would be based on how much capacity we need at our DR site. If we only cared about replicating 4 Tb to our DR site, then the DR node would only need a VL1 node license and a total of 4 Tb of capacity licensing (i.e., a VL1 license + three additional 1 Tb capacity licenses, since 1 Tb of capacity is included with the VL1 license).
At this point, no new SANmelody licenses are being sold – although, if you need to, you can still upgrade an existing SANmelody license to handle more storage. If you’re an existing SANmelody customer with current software maintenance, rest assured that you will be entitled to upgrade to SANsymphony-V as a benefit of your software maintenance coverage. However, there will not be a mechanism that allows for an easy in-place upgrade until sometime in Q3. In the meantime, an upgrade from SANmelody to SANsymphony-V would entail a complete rebuild from the ground up. (Which we would be delighted to do for you if you just can’t wait for the new features.)
