Some embodiments provide a method of providing distributed storage services to a host computer from a network interface card (NIC) of the host computer. At the NIC, the method accesses a set of one or more external storages operating outside of the host computer through a shared port of the NIC that is not only used to access the set of external storages but also for forwarding packets not related to an external storage. In some embodiments, the method accesses the external storage set by using a network fabric storage driver that employs a network fabric storage protocol to access the external storage set. The method presents the external storage as a local storage of the host computer to a set of programs executing on the host computer. In some embodiments, the method presents the local storage by using a storage emulation layer on the NIC to create a local storage construct that presents the set of external storages as a local storage of the host computer.

Systems and techniques are described for analyzing input output I/O traces. One of the techniques includes receiving an I/O trace, the I/O trace identifying a temporal sequence of previously submitted I/O requests; partitioning the I/O trace into a plurality of partitions based on a load pattern of the I/O requests in the I/O trace and a data access pattern of the I/O requests in the I/O trace; and generating a signature for each partition, wherein the signature for each of the partitions identifies characteristics of the I/O requests in the partition, and wherein the characteristics of the I/O requests in the partition include the load pattern of the I/O requests in the partition and the data access pattern of the I/O requests in the partition.
