Allegro 1000 series appliances are cost-efficient entry-level versions for 1 GBit/s to 10 GBit/s analysis of up to 10,000 servers. These network tools provide a highly accurate analysis of an entire location. Depending on the existing network traffic, this is enough for a complete analysis of all data from the several previous days which can be retrieved in real-time from the in-memory database. All Allegro 1000 appliances can be expanded with SFP+ ports, packet ring buffers and additional in-memory database storage. The SFP+ ports allow an analysis of both short- and long-range fiber connections. The Allegro 1000 series can also be transparently installed inline in Spanning Tree or LACP trunks to analyse port extension errors.

The portable Allegro 1000 and the Allegro 1200 are available as 1 U rack units. Both appliances have the same processing power. The Allegro 1000 is designed as a portable system and therefore has only one expansion slot. The Allegro 1200 on the other hand offers two slots, one for extended network ports and the other for a large internal hard disk. Both appliances can also be equipped with a high-speed NVMe SSD.

The basic versions of the Allegro 1000 and 1200 have 2 x SFP+ for 1G and 10G SFP modules, 2 x 10GBase-T and 3 x 1GBaseT for analysis and 1 x 1GBase-T as a management port. In addition, there are expansion cards for up to 4 x SFP+ ports, 2 x 10GBase-T ports, 4 x 1GBase-T ports, 2 x SFP28, 2 x QSFP28 or 2 x SFP+ with GPS connections for exact time stamps in the nanosecond range. The basic version is equipped with a 16 GB in-memory database. This can be expanded up to 512 GB.

Internal hard disks or NVMe SSD can be installed as ring buffers. With the NVMe SSD, a continuous write speed of up to 10 GBit/s is possible. As with the Allegro 200, external USB3 HDDs or SSDs can also be connected.

Historical data traffic stored in the ring buffer can be extracted in Pcap format and further processed with Wireshark (for example).
